Lexar SL500 Portable SSD Review: Silicon Motion SM2320 and YMTC NAND in a Potent Package

23 avril 2024 à 12:00

Lexar has a long history of serving the flash-based consumer storage market in the form of SSDs, memory cards, and USB flash drives. After having started out as a Micron brand, the company was acquired by Longsys which has diversified its product lineup with regular introduction of new products. Recently, the company announced a number of portable SSDs targeting different market segments. The Lexar SL500 Portable SSD is one of the moderately priced 20 Gbps PSSDs in that set.

The SL500 is able to achieve its price point thanks to the use of a native USB flash controller - the Silicon Motion SM2320. The unique aspect is the use of YMTC 3D TLC NAND (compared to the usual Micron or BiCS NAND that we have seen in previous SM2320-based PSSDs). Read on for a detailed look at the SL500, including an analysis of its internals and evaluation of its performance consistency, power consumption, and thermal profile.

The Eurocom 780W AC Power Adapter Review: Big Power For Big Laptops

22 avril 2024 à 13:00

While desktop PC power supplies receive the bulk of enthusiasts’ attention for good reasons – not the least of which being the vast selection of options that comes from being a standardized part – power supplies as a whole aren’t just a concern for big PCs. With the majority of PC sales having flipped to notebook sales some years ago, notebook power supplies already lead the market in volume. And while most laptops don’t need the kind of massively powered PSUs that dominate the desktop space, even that is slowly changing as desktop replacement-class laptops increasingly grow in performance and power consumption.

Perhaps the poster-child for the high-performance, high-powered laptop is Eurocom, who has a long history of developing heavy-duty DTR laptops that are all but portable desktop systems. Following recent trends in GPU power consumption and in GPU popularity for both gaming and AI workloads, the company has been selling a range of “mobile supercomputers”, which are practically large, tailor-made laptops that rival even the best of desktop computers – and have the power requirements to match.

In order to power their own high-end laptops, Eurocom has developed a rather unusual 780W AC adapter for high-performance laptops. Intended to power the most powerful of powerful laptops, their latest power adapter can supply over three-quarters of a kilowatt of DC power; a desktop-like wattage for a desktop-like device. It’s a laptop power adapter that’s unique in its scale, and with some room to scale up even further.

Eurocom has offered this adapter for a few years now. But it’s taken on a new life as more laptops have been released that use such a large adapter (or two smaller 300W-ish power adapters). And, critically, Eurocom has made additional DC cable/connector sets for other manufactuers’ laptops, significantly increasing the number of systems it’s compatible with. Currently, Eurocom offers DC cables for the following laptops:

  • Alienware M17x M18x; 1x DC Cable ; w/ barrel AW connector; 193cm/6.4ft 
  • Alienware AREA 51m; 1x DC Cable + Splitter Box w/ 2x barrel AW connectors; 152cm/5ft

  • MSI laptops & MSI Trident AS Gaming Desktops; 1x DC Cable; w/ 4-pin round connector; 182cm / 6ft 

The Eurocom 780W AC Adapter

Externally, the Eurocom 780W AC adapter looks like a hybrid between a PC PSU and a laptop adapter. It is shaped like an oversized laptop AC adapter but has a metallic body and cooling vents/fans. Eurocom advertises that it weighs “only 1.34kg”, which is the weight of an entire 14-inch laptop by comparison, but is relatively lightweight for a PSU with that kind of power output. The company logo is debossed across the top side of the adapter, with four round anti-slip pads found at its bottom. Care needs to be taken while moving it around because the metallic edges and weight can spell trouble for wooden surfaces.

Eurocom installed a small information display on the AC adapter, which shows the current, voltage, and power output, as well as the temperature of the adapter. It is not perfectly accurate – we can see it was reading a 12W load without a DC cable attached to the adapter – but it works as a basic reference. Next to it, there is a heavy-duty metallic connector for the DC cable. On the other side we can find a typical three-prong C14 AC cable receptacle, as well as an on/off switch, which is not something commonly found on laptop AC adapters.

 

Opening up the chassis, we can see that the Eurocom 780W AC adapter is not unlike common PC PSUs – just less complex due to the need to only generate a single 20V rail. The basic layout is identical, with an AC filter at the input consisting of four Y capacitors, two X capacitors, and two substantial filtering inductors, that leads to a rectifying bridge. The GBJ1508 bridge is made by HY Electronic Cayman Ltd, a Taiwanese company we're encountering for the first time.

 

Then we have an APFC circuitry with a massive Aishi 450V/560μF capacitor and a large filtering coil being its passive components, with a Toshiba K31N60W regulator on the same heatsink as the two MOSFETs that form a typical half-bridge configuration. Following that we have a small transformer and two Infineon 045N10N MOSFETs to generate the 20V power output. Cooling is provided by two Protechnic Electric MGT3812XB-W20 38 mm fans, which are small but high quality products with a double-ball bearing engine.

Test Results (~25°C Ambient)

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, and various other bits and parts. 

The average efficiency of the Eurocom 780W AC adapter is very high, at 91.6% when the PSU is powered from an 230V AC source and drops down to 90.9% when powered from an 115V AC source. There is no 80Plus or similar efficiency certification covering this PSU, but there is legislation such as the Ecodesign 2019/1782 directive, and, even though the manufacturer does not fully publish its performance specs as the directive requires, the Eurocom 780W adapter seems to easily meet them. We must mention that this kind of PSU has an advantage over classic PC PSUs because it only generates a single voltage line, and conversion losses are lower, so it should not be directly compared to any multi-voltage output PSU.

The two small fans of the Eurocom 780W AC adapter seem hardwired to the power output of the unit, largely ignoring the temperature of the adapter and adjusting their speed only according to the load. Up to 40% load, which should cover the power needs of most gaming laptops anyway, the adapter is practically entirely silent. The speed of the fan gradually increases when the load is greater than 330 Watts, reaching terrifying noise figures at maximum load. Given the nature of the adapter, it is highly unlikely that it will operate at such high a load for prolonged periods of time, as even the laptops that require 2x330 Watt adapters will not continuously sustain such a high load.

Power Supply Quality 

The electrical performance of the Eurocom 780W AC adapter is surprisingly good compared to its datasheet specifications. Eurocom claims a maximum voltage ripple of 200 mV but we recorded a maximum of 116 mV, which is alright for a 20 V rail and better than we expected due to the mediocre secondary side filtering. Voltage regulation is very good, at just 1.2% across the nominal load range.

Main Output
Load (Watts) 158.03 394.68 586.46 780.78
Load (Percent) 20% Load 50% Load 75% Load 100% Load
  Amperes Volts Amperes Volts Amperes Volts Amperes Volts
20 V 7.8 20.26 19.5 20.24 29.25 20.05 39 20.02

Voltage Ripple (mV)
20% Load 50% Load 75% Load 100% Load
20V 1.2% 44 66 82 116

During our routine evaluation, we examine the fundamental protection features of all power supply units we review, including Over Current Protection (OCP), Over Voltage Protection (OVP), Over Power Protection (OPP), and Short Circuit Protection (SCP). The Eurocom 780W AC adapter behaves quite oddly here, as it has a rated output of 39 A and a maximum output of 45 A for 25 ms. However, we were able to draw 50 A from the unit, which is nearly 1000 Watts, for several minutes without triggering the OCP/OPP protection. The PSU did not show any serious signs of stress or overheating over that time, nor poor electrical performance. The OPP protection triggers immediately once the load is greater than 50.3 A – and also immediately resets and restarts the PSU when the load drops below 50.2A. It would seem that this platform was initially designed to be significantly more powerful and the OEM “forgot” to adjust the OCP/OPP trigger points.

Conclusion

The Eurocom 780W AC adapter melds raw power with innovation, presenting a piece that's as formidable as it is intriguing. With its substantial weight and metallic edges, it demands respect and caution, especially on delicate surfaces. However, its weight is justified by the impressive power output it delivers, making it a powerhouse that somewhat overshadows its bulky, heavy-set design. The inclusion of a display for monitoring performance is a smart touch, though its accuracy leaves room for improvement.

On the inside, Eurocom doesn't skimp on quality. The adapter's internals are a testament to careful selection and engineering, closely mirroring the complexity and efficiency of high-end PC PSUs. Its cooling system, though compact, functions well and provides good performance without compromising on noise levels — at least under most loads. That said, the adapter's noise profile at maximum load might not be everyone's cup of tea, hinting at a balance yet to be perfected between power and tranquility.

Overall, Eurocom's 780W AC adapter boasts commendable efficiency and electrical performance. But as a premium-priced product – a complete unit and cable will set you back at least $429 – it could benefit from a touch more finesse, particularly in terms of user safety and operational noise at high loads. Otherwise, I'm personally a bit surprised that Eurocom isn't offering a open-ended cable for DIY enthusiasts, which could broaden its appeal and utility. Such an addition would not only cater to a wider audience but also underscore Eurocom's commitment to versatility and innovation.

In sum, while the adapter stands out for its power and performance, there's also a clear avenue for Eurocom to enhance its appeal through minor, yet impactful, improvements.

JEDEC Extends DDR5 Memory Specification to 8800 MT/s, Adds Anti-Rowhammer Features

22 avril 2024 à 12:00

When JEDEC released its DDR5 specification (JESD79) back in 2020, the standard setting organization defined precise specs for modules with speed bins of up to 6400 MT/s, while leaving the spec open to further expansions with faster memory as technology progressed. Now, a bit more than three-and-a-half years later, and the standards body and its members are gearing up to release a faster generation of DDR5 memory, which is being laid out in the newly updated JESD79-JC5 specification. The latest iteration of the DDR5 spec defines official DDR timing specifications up to 8800 MT/s, as well as adding some new features when it comes to security.

Diving in, the new specification outlines settings for memory chips (on all types of memory modules) with data transfer rates up to 8800 MT/s (AKA DDR5-8800). This suggests that all members of the JESD79 committee that sets the specs for DDR5 — including memory chip makers and memory controller designers — agree that DDR5-8800 is a viable extension of the DDR5 specification both from performance and cost point of view. Meanwhile, the addition of higher speed bins is perhaps enabled by another JEDEC feature introduced in this latest specification, which is the Self-Refresh Exit Clock Sync for I/O training optimization.

DDR5-8400 A 8400 60 60 60 14.29 67.2
DDR5-8800 A 8800 62 62 62 14.09 70.4

When it comes to the JEDEC standard for DDR5-8800, it sets relatively loose timings of CL62 62-62 for A-grade devices and CL78 77-77 for lower-end C-grade ICs. Unfortunately, the laws of physics driving DRAM cells have not improved much over the last couple of years (or decades, for that matter), so memory chips still must operate with similar absolute latencies, driving up the relative CAS latency. In this case 14ns remains the gold standard, with CAS latencies at the new speeds being set to hold absolute latencies around that mark. But in exchange for systems willing to wait a bit longer (in terms of cycles) for a result, the new spec improves the standard's peak memory bandwidth by 37.5%.

This of course is just the timings set in the JEDEC specification, which is primarily of concern for server vendors. So we'll have to see just how much harder consumer memory manufacturers can push things for their XMP/EXPO-profiled memory. Extreme overclockers are already hitting speeds as high as 11,240 MT/s with current-generation DRAM chips and CPUs, so there may be some more headroom to play with in the next generation.

Meanwhile, on the security front, the updated spec makes a couple of changes that have been put in place seemingly to address rowhammer-style exploits. The big item here is Per-Row Activation Counting (PRAC), which true to its name, enables DDR5 to keep a count of how often a row has been activated. Using this information, memory controllers can then determine if a memory row has been excessively activated and is at risk of causing a neighboring row's bits to flip, at which point they can back off to let the neighboring row properly refresh and the data re-stabilize.

Notably here, the JEDEC press release doesn't use the rowhammer name at any point (unfortunately, we haven't been able to see the specification itself). But based on the description alone, this is clearly intended to thwart rowhammer attacks, since these normally operate by forcing a bit flip between refreshes through a large number of activations.

Digging a bit deeper, PRAC seems to be based on a recent Intel patent, Perfect Row Hammer Tracking with Multiple Count Increments (US20220121398A1), which describes a very similar mechanism under the name "Perfect row hammer tracking" (PRHT). Notably, the Intel paper calls out that this technique has a performance cost associated with it because it increases the overall row cycle time. Ultimately, as the vulnerability underpinning rowhammer is a matter of physics (cell density) rather than logic, it's not too surprising to see that any mitigation of it comes with a cost.

The updated DDR5 specification also deprecates support for Partial Array Self Refresh (PASR) within the standard, citing security concerns. PASR is primarily aimed at power efficiency for mobile memory to begin with, and as a refresh-related technology, presumably overlaps some with rowhammer – be it a means to attack memory, or an obstruction to defending against rowhammer. Either way, with mobile devices increasingly moving to low-power optimized LPDDR technologies anyhow, the depreciation of PASR does not immediately look like a major concern for consumer devices.

SK Hynix and TSMC Team Up for HBM4 Development

19 avril 2024 à 15:00

SK hynix and TSMC announced early on Friday that they had signed a memorandum of understanding to collaborate on developing the next-generation HBM4 memory and advanced packaging technology. The initiative is designed to speed up the adoption of HBM4 memory and solidify SK hynix's and TSMC's leading positions in high-bandwidth memory and advanced processor applications.

The primary focus of SK hynix's and TSMC's initial efforts will be to enhance the performance of the HBM4 stack's base die, which (if we put it very simply) acts like an ultra-wide interface between memory devices and host processors. With HBM4, SK hynix plans to use one of TSMC's advanced logic process technologies to build base dies to pack additional features and I/O pins within the confines of existing spatial constraints. 

This collaborative approach also enables SK hynix to customize HBM solutions to satisfy diverse customer performance and energy efficiency requirements. SK hynix has been touting custom HBM solutions for a while, and teaming up with TSMC will undoubtedly help with this.

"TSMC and SK hynix have already established a strong partnership over the years. We've worked together in integrating the most advanced logic and state-of-the art HBM in providing the world's leading AI solutions," said Dr. Kevin Zhang, Senior Vice President of TSMC's Business Development and Overseas Operations Office, and Deputy Co-Chief Operating Officer. "Looking ahead to the next-generation HBM4, we're confident that we will continue to work closely in delivering the best-integrated solutions to unlock new AI innovations for our common customers."

Furthermore, the collaboration extends to optimizing the integration of SK hynix's HBM with TSMC's CoWoS advanced packaging technology. CoWoS is among the most popular specialized 2.5D packaging process technologies for integrating logic chips and stacked HBM into a unified module.

For now, it is expected that HBM4 memory will be integrated with logic processors using direct bonding. However, some of TSMC's customers might prefer to use an ultra-advanced version of CoWoS to integrate HBM4 with their processors.

"We expect a strong partnership with TSMC to help accelerate our efforts for open collaboration with our customers and develop the industry's best-performing HBM4," said Justin Kim, President and the Head of AI Infra at SK hynix. "With this cooperation in place, we will strengthen our market leadership as the total AI memory provider further by beefing up competitiveness in the space of the custom memory platform."

AMD Announces Ryzen Pro 8000 and Ryzen Pro 8040 Series CPUs: Commercial Desktop Gets AI

19 avril 2024 à 14:00

AMD is looking to drive the AI PC market with options across multiple product lines, which aren't limited to consumer processors. While primarily designed for the commercial sector, AMD has announced the Ryzen Pro 8000 'Phoenix' series of APUs for desktops, which AMD claims is the first professional-grade CPU to include an NPU designed to provide on-chip AI neural processing capabilities. AMD has also announced the Ryzen Pro 8040 'Hawk Point' series of mobile processors designed for commercial laptops and notebooks.

AMD's Ryzen Pro 8000 and Ryzen Pro 8040 series processors come with support from AMD's Pro Manageability and AMD Pro Business Ready suites and are built with AMD's current generation Zen 4 cores. The Ryzen Pro 8000 and Ryzen Pro 8040 series processors are similar to their consumer-level counterparts. However, they have additional security features such as AMD Memory Guard, AMD Secure Processor, and Microsoft Pluton.

Touching on the differentiating factors between the non-Pro-consumer chips and the Ryzen Pro series, there is plenty for the commercial and enterprise market regarding security. In what is a first, the Ryzen Pro 8000 series is the first desktop platform to integrate Microsoft Pluton security features designed to protect when connecting to the cloud. Other features include AMD Memory Guard, which encrypts login credentials, keys, and text files stored in the DRAM. AMD Pro Security ties the AMD Zen 4 shadow stack and other layers in directly with the software stack, which, in this case, is Microsoft Windows 11 OS security. 

Another notable feature that AMD is hammering home is the on-chip AI capabilities of the included Ryzen AI neural processor unit (NPU), which allows enterprises to run AI workloads locally to mitigate privacy concerns by transferring data to and from the cloud. Although the current generation of NPUs embedded into processors are limited in what they can do, Ryzen AI is a driving factor within the AI PC, as manufacturers and SDVs are looking to utilize AI-accelerated features built into software, such as Microsoft with their AI-powered Copilot tool.

Although there are requirements that now must be met to ensure a PC is considered an 'AI PC,' Microsoft announced that their AI PC requirement is 45 TOPS of performance from the NPU alone, which none of the current generation of chips from AMD and Intel currently meet. In the desktop space, AMD currently has the lead as Intel has presently no offerings with an NPU, although, in the mobile space, AMD with their Ryzen 8040 (Hawk Point) and Intel with their Meteor Lake processors provide plenty of choice for users.

Looking at the AMD Ryzen Pro 8000 series, AMD has announced eight new processors that include the same specifications as the non-Pro Ryzen 8000G APU counterparts. Two primary types of Ryzen Pro 8000 processors are set to be available: four with a configurable TDP of between 45 and 65 W and four with a flat TDP of 35 W for lower-powered environments. Leading the line-up is the Ryzen 7 Pro 8700G, which is identical in core specifications to the Ryzen 7 8700G APU, and has an 8C/16T (Zen 4) configuration with a base frequency of 4.2 GHz and a boost frequency of up to 5.1 GHz.

Even the Ryzen 7 Pro 8700GE, which is the 35 W version, has a 5.1 GHz boost frequency, although it has a slower base clock of 3.65 GHz. Both models have 16 MB of L3 cache, including AMD's integrated Radeon 780M (12 CUs) mobile graphics. All of the eight Ryzen Pro 8000 series models range from 4C/8T offerings with 8 MB of L3 cache and 4.9 GHz boost clocks, 6C/12T models with 5.0 GHz boost clocks and 16 MB of L3 cache, and those as mentioned above 8700/8700GE with 8C/16T.

While we take all performance figures given by manufacturers and vendors with a pinch of salt, AMD claims their Ryzen Pro 8000 series offers up to 19% better performance than Intel's 14th-gen Core series processors. AMD's match-up is the Ryzen 7 Pro 8700G vs. the Intel Core i7-14700, with AMD claiming a 47% victory in the Passmark 11 benchmark and 3X the graphics performance in 3D Mark Time Spy. This isn't entirely surprising because the Ryzen 7 Pro 8700G benefits from integrated RDNA3 graphics and AMD's Zen 4 cores.

*Ryzen 5 Pro 8540U is the only chip without AMD's Ryzen AI NPU

Moving onto AMD's latest Ryzen Pro 8040 processors for the mobile market, AMD has refreshed their Hawk Point family for the enterprise market. AMD has eight new processors, which are segmented into two families, the HS series and the U series. The HS series has five new chips, which range from 6C/12T up to 8C/16T, all with varying levels of clock speed and TDPs. At the top of the line-up is the Ryzen 9 Pro 8945HS, which is a direct replacement for the Ryzen 9 Pro 7940HS, and as such, it comes with the same 4.0 GHz base clock and 5.2 GHz boost clocks.

Pivitong to TDP, AMD offers the Ryzen 9 Pro 8945HS, Ryzen 7 Pro 8845HS, and Ryzen 5 Pro 8645HS with a configurable TDP of between 35 and 54 W. In contrast, the Ryzen 7 Pro 8840HS and the Ryzen 5 Pro 8640HS are designed for lower-powered laptops with a cTDP of 20-28 W. Regarding cache, all of the announced Ryzen Pro 8040 series models come with 16 MB of L3 Cache. At the same time, specifications such as the integrated graphics and clock speeds all correspond to the consumer line-up, the Ryzen 8040 series.

AMD's in-house performance figures show the Ryzen 7 Pro 8840U at 15 W performing better than Intel's Core Ultra 7 165H at 28 W. Still, as we always do with performance figures provided by vendors, take these with a pinch of salt. AMD claims a 30% combined increase in performance across the board in workloads, including Geekbench v6, Blender, PCMark 10, PCMark Night Raid, and UL Procyon. While there are plenty of different areas where performance gains and losses can be achieved, AMD does claim that their Ryzen 9 Pro 8945HS at 45 W vs. the Intel Core Ultra 9 185H at 45 W is 50% better in Topaz Labs Video AI Gaia 4X software; they did both use discrete graphics in this test according to AMD's slide deck.

The other notable thing is that all of the Ryzen Pro 8040 series processors, except the bottom SKU, the Ryzen 5 Pro 8540U, come with AMD's Ryzen AI NPU integrated into the silicon. While the AI PC ecosystem is still growing, AMD and over 150+ ISVs look to continue the trend that AI will power more software features in the future than we've seen so far. We are still in the infancy stage of the ecosystem despite much of the marketing targeting the AI functionality, but as we see higher-performing NPUs coming in the next generation of chips, at least ones that can match Microsoft 45 NPU TOPS requirement to run Copilot locally, much of the benefit of the NPU is currently down to how much power can be saved.

The introduction of the Ryzen Pro 8000/8040 series completes AMD's commercial client platform, along with the readily available Ryzen Threadripper Pro 7000-WX series for commercial and professional workstations. What sets these AMD Ryzen Pro series processors apart from the consumer (non-Pro) variants is support for the AMD Pro Manageability toolkit, which includes features such as cloud-based remote manageability to enable off-site IT technicians the ability to access devices remotely, as well WPA3 SAE encryption, which provides client-to-cloud protection for enterprises over shared networks.

AMD has not announced when the Ryzen Pro 8000 series APUs or the Ryzen Pro 8040 mobile chips will be available for purchase. However, we expect a wide array of OEMs, such as HP and Lenovo, to be already in the process of readying solutions that should hit the market soon.

TSMC Posts Q1'24 Results: 3nm Revenue Share Drops Steeply, but HPC Share Rises

19 avril 2024 à 12:00

Taiwan Semiconductor Manufacturing Co. this week released its financial results for Q1 2024. Due to a rebound in demand for semiconductors, the company garned $18.87 billion in revenue for the quarter, which is up 12.9% year-over-year, but a decline of 3.8% quarter-over-quarter. The company says that in increase in demand for HPC processors (which includes processors for AI, PCs, and servers) drove its revenue rebound in Q1, but surprisingly, revenue share of TSMC's flagship N3 (3nm-class) process technology declined steeply quarter-over-quarter.

"Our business in the first quarter was impacted by smartphone seasonality, partially offset by continued HPC-related demand," said Wendell Huang, senior VP and chief financial officer of TSMC. "Moving into second quarter 2024, we expect our business to be supported by strong demand for our industry-leading 3nm and 5nm technologies, partially offset by continued smartphone seasonality."

In the first quarter of 2024, N3 wafer sales accounted for 9% of the foundry's revenue, down from 15% in Q4 2023, and up from 6% in Q3 2023. In terms of dollars, TSMC's 3nm production brought in around $1.698 billion, which is lower than $2.943 billion in the previous quarter. Meanwhile, TSMC's other advanced process technologies increased their revenue share: N5 (5 nm-class) accounted for 37% (up from 35%), and N7 (7 nm-class) commanded 19% (up from 17%). Though both remained relatively flat in terms of revenue, at $6.981 billion and $3.585 billion, respectively.

Generally, advanced technology nodes (N7, N5, N3) generated 65% of TSMC's revenue (down 2% from Q4 2023), while the broader category of FinFET-based process technologies contributed 74% to the company's total wafer revenue (down 1% from the previous quarter).

TSMC itself attributes the steep decline of N3's contribution to seasonally lower demand for smartphones in the first quarter as compared to the fourth quarter, which may indeed be the case as demand for iPhones typically slowdowns in Q1. Along those lines, there have also been reports about a drop in demand for the latest iPhones in China.

But even if A17 Pro production volumes are down, Apple remains TSMC's lead customer for N3B, as the fab also produces their M3, M3 Pro, and M3 Max processors on the same node. These SoCs are larger in terms of die sizes and resulting costs, so their contribution to TSMC's revenue should be quite substantial.

"Moving on to revenue contribution by platform. HPC increased 3% quarter-over-quarter to account for 46% of our first quarter revenue," said Huang. "Smartphone decreased 16% to account for 38%. IoT increased 5% to account for 6%. Automotive remained flat and accounted for 6%, and DCE increased 33% to account for 2%."

Meanwhile, as demand for AI and HPC processors will continue to increase in the coming years, TSMC expects its HPC platform to keep increasing its share in its revenue going forward.

"We expect several AI processors to be the strongest driver of our HPC platform growth and the largest contributor in terms of our overall incremental revenue growth in the next several years," said C.C. Wei, chief executive of TSMC.

ASML Patterns First Wafer Using High-NA EUV Tool, Ships Second High-NA Scanner

18 avril 2024 à 13:00

This week ASML is making two very important announcements related to their progress with high numerical aperature extreme ultraviolet lithography (High-NA EUV). First up, the company's High-NA EUV prototype system at its fab in Veldhoven, the Netherlands, has printed the first 10nm patterns, which is a major milestone for ASML and their next-gen tools. Second, the company has also revealed that it's second High-NA EUV system is now out the door as well, and has been shipped to an unnamed customer.

"Our High-NA EUV system in Veldhoven printed the first-ever 10 nanometer dense lines," a statement by ASML reads. "Imaging was done after optics, sensors and stages completed coarse calibration. Next up: bringing the system to full performance. And achieving the same results in the field."

Alongside the system shipped to Intel at the end of 2023, ASML has retained their own Twinscan EXE:5000 scanner at their Veldhoven, Netherlands, facility, which is what the company is using for further research and development into High-NA EUV. Using that machine, the company has been able to print dense lines spaced 10 nanometers apart, which is a major milestone in photolithography development. Previously, only small-scale, experimental lab machines have been able to achieve this kind of a resolution. Eventually, High-NA EUV tools will achieve a resolution of 8 nm, which will be instrumental to build logic chips on technologies beyond 3 nm.

Intel's Twinscan EXE:5000 scanner at its D1X fab near Hillsboro, Oregon is also close behind, and its assembly is said to be nearing completion. That machine will be primarily used for Intel's own High-NA EUV R&D, with Intel slated to use its successor — the commercial-grade Twinscan EXE:5200 — to produce its chips on its Intel 14A (1.4 nm-class) in mass quantities in 2026 – 2027.

But Intel will not be the only chipmaker that gets to experiment with a High-NA EUV scanner for very long. As revealed by ASML, the company recently started shipping another Twinscan EXE:5000 machine to yet another customer. The fab tool maker is not disclosing the client, but previously it has said that all of leading logic and memory producers are in the process of procuring High-NA tools for R&D purposes, so the list of 'suspects' is pretty short.

"Regarding High-NA, or 0.55 NA EUV, we shipped our first system to a customer and this system is currently under installation," said Christophe Fouquet, chief business officer of ASML, at the company's earnings conference call with analysts and investors. "We started to ship the second system this month and its installation is also about to start."

While Intel plans to adopt High-NA EUV tools ahead of the industry, other chipmakers seem to a bit more cautious and plan to rely on risky yet already known Low-NA EUV double patterning method for production a 3 nm and 2 nm. Still, regardless of the exact timing for a transition, all of the major fabs will be relying on High-NA EUV tools in due time. So all parties have an interest in how ASML's R&D turns out.

"The customer interest for our [High-NA] system lab is high as this system will help both our Logic and Memory customers prepare for High-NA insertion into their roadmaps," said Fouquet. "Relative to 0.33 NA, the 0.55 NA system provides finer resolution enabling an almost 3x increase in transistor density, at a similar productivity, in support of sub-2nm Logic and sub-10nm DRAM nodes."

Intel and Sandia National Labs Roll Out 1.15B Neuron “Hala Point” Neuromorphic Research System

17 avril 2024 à 15:00

While neuromorphic computing remains under research for the time being, efforts into the field have continued to grow over the years, as have the capabilities of the specialty chips that have been developed for this research. Following those lines, this morning Intel and Sandia National Laboratories are celebrating the deployment of the Hala Point neuromorphic system, which the two believe is the highest capacity system in the world. With 1.15 billion neurons overall, Hala Point is the largest deployment yet for Intel’s Loihi 2 neuromorphic chip, which was first announced at the tail-end of 2021.

The Hala Point system incorporates 1152 Loihi 2 processors, each of which is capable of simulating a million neurons. As noted back at the time of Loihi 2’s launch, these chips are actually rather small – just 31 mm2 per chip with 2.3 billion transistors each, as they’re built on the Intel 4 process (one of the only other Intel chips to do so, besides Meteor Lake). As a result, the complete system is similarly petite, taking up just 6 rack units of space (or as Sandia likes to compare it to, about the size of a microwave), with a power consumption of 2.6 kW. Now that it’s online, Hala Point has dethroned the SpiNNaker system as the largest disclosed neuromorphic system, offering admittedly just a slightly larger number of neurons at less than 3% of the power consumption of the 100 kW British system.


A Single Loihi 2 Chip (31 mm2)

Hala Point will be replacing an older Intel neuromorphic system at Sandia, Pohoiki Springs, which is based on Intel’s first-generation Loihi chips. By comparison, Hala Point offers ten-times as many neurons, and upwards of 12x the performance overall,

Both neuromorphic systems have been procured by Sandia in order to advance the national lab’s research into neuromorphic computing, a computing paradigm that behaves like a brain. The central thought (if you’ll excuse the pun) is that by mimicking the wetware writing this article, neuromorphic chips can be used to solve problems that conventional processors cannot solve today, and that they can do so more efficiently as well.

Sandia, for its part, has said that it will be using the system to look at large-scale neuromorphic computing, with work operating on a scale well beyond Pohoiki Springs. With Hala Point offering a simulated neuron count very roughly on the level of complexity of an owl brain, the lab believes that a larger-scale system will finally enable them to properly exploit the properties of neuromorphic computing to solve real problems in fields such as device physics, computer architecture, computer science and informatics, moving well beyond the simple demonstrations initially achieved at a smaller scale.

One new focus from the lab, which in turn has caught Intel’s attention, is the applicability of neuromorphic computing towards AI inference. Because the neural networks themselves behind the current wave of AI systems are attempting to emulate the human brain, in a sense, there is an obvious degree of synergy with the brain-mimicking neuromorphic chips, even if the algorithms differ in some key respects. Still, with energy efficiency being one of the major benefits of neuromorphic computing, it’s pushed Intel to look into the matter further – and even build a second, Hala Point-sized system of their own.

According to Intel, in their research on Hala Point, the system has reached efficiencies as high as 15 TOPS-per-Watt at 8-bit precision, albeit while using 10:1 sparsity, making it more than competitive with current-generation commercial chips. As an added bonus to that efficiency, the neuromorphic systems don’t require extensive data processing and batching in advance, which is normally necessary to make efficient use of the high density ALU arrays in GPUs and GPU-like processors.

Perhaps the most interesting use case of all, however, is the potential for being able to use neuromorphic computing to enable augmenting neural networks with additional data on the fly. The idea behind this being to avoid re-training, as current LLMs require, which is extremely costly due to the extensive computing resources required. In essence, this is taking another page from how brains operate, allowing for continuous learning and dataset augmentation.

But for the moment, at least, this remains a subject of academic study. Eventually, Intel and Sandia want systems like Hala Point to lead to the development of commercial systems – and presumably, at even larger scales. But to get there, researchers at Sandia and elsewhere will first need to use the current crop of systems to better refine their algorithms, as well as better figure out how to map larger workloads to this style of computing in order to prove their utility at larger scales.

Samsung Unveils 10.7Gbps LPDDR5X Memory - The Fastest Yet

17 avril 2024 à 14:00

Samsung today has announced that they have developed an even faster generation of LPDDR5X memory that is set to top out at LPDDR5X-10700 speeds. The updated memory is slated to offer 25% better performance and 30% greater capacity compared to existing mobile DRAM devices from the company. The new chips also appear to be tangibly faster than Micron's LPDDR5X memory and SK hynix's LPDDR5T chips.

Samsung's forthcoming LPDDR5X devices feature a data transfer rate of 10.7 GT/s as well as maximum capacity per stack of 32 GB. This allows Samsung's clients to equip their latest smartphones or laptops with 32 GB of low-power memory using just one DRAM package, which greatly simplifies their designs. Samsung says that 32 GB of memory will be particularly beneficial for on-device AI applications.

Samsung is using its latest-generation 12nm-class DRAM process technology to make its LPDDR5X-10700 devices, which allows the company to achieve the smallest LPDDR device size in the industry, the memory maker said.

In terms of power efficiency, Samsung claims that they have integrated multiple new power-saving features into the new LPDDR5X devices. These include an optimized power variation system that adjusts energy consumption based on workload, and expanded intervals for low-power mode that extend the periods of energy saving. These innovations collectively enhance power efficiency by 25% compared to earlier versions, benefiting mobile platforms by extending battery life, the company said.

“As demand for low-power, high-performance memory increases, LPDDR DRAM is expected to expand its applications from mainly mobile to other areas that traditionally require higher performance and reliability such as PCs, accelerators, servers and automobiles,” said YongCheol Bae, Executive Vice President of Memory Product Planning of the Memory Business at Samsung Electronics. “Samsung will continue to innovate and deliver optimized products for the upcoming on-device AI era through close collaboration with customers.”

Samsung plans to initiate mass production of the 10.7 GT/s LPDDR5X DRAM in the second half of this year. This follows a series of compatibility tests with mobile application processors and device manufacturers to ensure seamless integration into future products.

Samsung To Receive $6.4 Billion Under CHIPS Act to Build $40 Billion Fab in Texas

16 avril 2024 à 21:00

Samsung Electronics this week was awarded up to $6.4 billion from the U.S. government under the CHIPS and Science Act to build its new fab complex in Taylor, Texas. This is the third major award under the act in the last month, with all three leading-edge fabs – Intel, TSMC, and now Samsung – receiving multi-billion dollar funding packages under the domestic chip production program. Overall, the final price tag on Samsung's new fab complex is expected to reach $40 billion by the time it's completed later this decade.

Samsung's CHIPS Act funding was announced during a celebratory event attended by U.S. Secretary of Commerce Gina Raimondo and Samsung Semiconductor chief executive Kye Hyun Kyung.  During the event, Kyung outlined the strategic goals of the expansion, emphasizing that the additional funding will not only increase production capacity but also strengthen the entire local semiconductor ecosystem. Samsung plans to equip its fab near Taylor, Texas, with the latest wafer fab tools to produce advanced chips. The Financial Times reports that Samsung aims to produce semiconductors on its 2nm-class process technology starting 2026, though for now this is unofficial information.

"I am pleased to announce a preliminary agreement between Samsung and the Department of Commerce to bring Samsung's advanced semiconductor manufacturing and research and development to Texas," said Joe Biden, the U.S. president, in a statement. "This announcement will unleash over $40 billion in investment from Samsung, and cement central Texas's role as a state-of-the-art semiconductor ecosystem, creating at least 21,500 jobs and leveraging up to $40 million in CHIPS funding to train and develop the local workforce. These facilities will support the production of some of the most powerful chips in the world, which are essential to advanced technologies like artificial intelligence and will bolster U.S. national security."

Samsung has been a significant contributor to the Texas economy for decades, starting chip manufacturing in the U.S. in 1996. With previous investments totaling $18 billion in its Austin operations, Samsung's expansion into Taylor with an additional investment of at least $17 billion underscores its role as one of the largest foreign direct investors in U.S. history. The total expected investment in the new fab surpasses $40 billion, making it one of the largest for a greenfield project in the nation and transforming Taylor into a major hub for semiconductor manufacturing.

The CEO highlighted the substantial economic impact of Samsung's operations, noting a nearly double increase in regional economic output from $13.6 billion to $26.8 billion between 2022 and 2023. The ongoing expansion is projected to further stimulate economic growth, create thousands of jobs, and enhance the community's overall development.

“We are not just expanding production facilities; we’re strengthening the local semiconductor ecosystem and positioning the U.S. as a global semiconductor manufacturing destination.” said Kyung. “To meet the expected surge in demand from U.S. customers, for future products like AI chips, our fabs will be equipped for cutting-edge process technologies and help bring security to the U.S. semiconductor supply chain.”

Samsung is also committed to environmental sustainability and workforce development. The company plans to operate using 100% clean energy and incorporate advanced water management technologies. Additionally, it is investing in education and training programs to develop a new generation of semiconductor professionals. These initiatives include partnerships with educational institutions and programs tailored for military veterans.

In his remarks, Kyung expressed gratitude to President Biden, Secretary Raimondo, and other governmental and community supporters for their ongoing support. This collaborative effort between Samsung and various levels of government, as well as the local community, is pivotal in advancing America's semiconductor industry and ensuring its global competitiveness.

"Today’s announcement will help Samsung bring more semiconductor production, innovation, and jobs to U.S. shores, reinforcing America’s economy, competitiveness, and critical chip supply chains," a statememt by the Semiconductor Industry Associate reads. "We applaud Samsung for investing boldly in U.S.-based manufacturing and salute the U.S. Commerce Department for making significant headway in implementing the CHIPS Act’s manufacturing incentives and R&D programs. We look forward to continuing to work with leaders in government and industry to ensure the CHIPS Act remains on track to help reinvigorate U.S. chip manufacturing and research for many years to come."

NVIDIA Intros RTX A1000 and A400: Entry-Level ProViz Cards Get Ray Tracing

16 avril 2024 à 16:00

With NVIDIA’s Turing architecture turning six years old this year, the company has been retiring many of the remaining Turing products from its video card lineup. And today that spirit of spring cleaning is coming to the entry-level segment of NVIDIA’s professional visualization lineup, where NVIDIA is introducing a pair of new desktop cards based on their low-end Ampere hardware.

The new RTX A1000 and RTX A400 cards will be replacing the T1000/T600/T400 lineup, which was released three years ago in 2021. The new cards slot into the same entry-level category and finally finish fleshing out the RTX A series of proviz cards, offering NVIDIA’s Ampere-generation professional graphics technologies in the lowest-power, lowest-performance, lowest-cost configuration possible.

Notably, since the entry-level T-series were based on NVIDIA’s feature-limited TU11x silicon, which lacked ray tracing and tensor core support – the basis of NVIDIA’s RTX technologies and associated branding – this marks the first time these technologies will be available in NVIDIA’s entry-level desktop proviz cards. And accordingly, these are being promoted to RTX-branded video cards, ending the odd overlap with NVIDIA’s compute cards, which never carry RTX branding.

It goes without saying that as low-end cards, the ray tracing performance of either part is nothing to write home about, but it gives NVIDIA’s current proviz lineup a consistent set of graphics features from top to bottom.

Launch Date 04/2024 05/2024 05/2021 05/2021

Both the A1000 and A400 are based on the same board design, with NVIDIA doing away with any pretense of physical feature differentiation this time around (T400 was missing its 4th Mini DisplayPort). This means both cards are based on the GA107 GPU, sporting different core and memory configurations.

RTX A1000 is a not-quite-complete configuration of GA107, with 2304 CUDA cores and 72 tensor cores. This is paired with 8GB of GDDR6, which runs at 12Gbps, for a total of 192GB/second of memory bandwidth. The TDP of the card is 50 Watts, matching its predecessor.

Meanwhile RTX A400 is far more cut down, offering about a third of the active hardware on the GPU itself, and half the memory bandwidth. On paper this gives it around 40% of T1000’s performance, and half the memory bandwidth – or 96GB/second. Notably, despite the hardware cut-down, the official TDP is still 50 Watts, versus the 30 Watts of its predecessor. So at this point NVIDIA will soon cease offering a desktop proviz card lower than 50 Watts.

As noted before, both cards otherwise feature the same physical design, with a half-height half-length (HHHL) board with active cooling. As you’d expect from such low-TDP cards, these are single-slot cooler designs. Both cards feature a quartet of Mini DisplayPorts, with the same DP 1.4a functionality that we’ve seen across all of NVIDIA’s products for the last several years.

Finally, video-focused users will want to make note that the A1000/A400 have slightly different video capabilities. While A1000 gets access to both of GA107’s NVDEC video decode blocks, A400 only gets access to a single block – one more cutback to differentiate the two cards. Otherwise, both video cards get access to the GPU’s sole NVENC block.

According to NVIDIA, the RTX A1000 will be available starting today through its distribution partners. Meanwhile the RTX A400 will hit distribution channels in May, and with OEMs expected to begin offering the cards as part of their pre-built systems this summer.

SK hynix Tube T31 Stick SSD Review: Bridging Solution Springs A Surprise

15 avril 2024 à 12:00

SK hynix is one of the few vertically integrated manufacturers in the flash-based storage market. The company is well-established in the OEM market. A few years back, they also started exploring direct end-user products. Internal SSDs (starting with the Gold S31 and Gold P31) were the first out of the door. Late last year, the company introduced the Beetle X31 portable SSD, its first direct-attached storage product. In February, a complementary product was introduced - the Tube T31 Stick SSD.

The Beetle X31 is a portable SSD with a Type-C upstream port and a separate cable. The Tube T31 is a take on the traditional thumb drive with a male Type-A interface. The size of the Beetle X31 makes the use of a bridge solution obvious. Our investigation into the Tube T31 also revealed the use of the same internal SSD, albeit with a different bridge. Read on for a detailed look at the Tube T31, including an analysis of its internals and evaluation of its performance consistency, power consumption, and thermal profile.

Corsair Enters Workstation Memory Market with WS Series XMP/EXPO DDR5 RDIMMs

12 avril 2024 à 12:30

Corsair has introduced a family of registered memory modules with ECC that are designed for AMD's Ryzen Threadripper 7000 and Intel's Xeon W-2400/3400-series processors. The new Corsair WS DDR5 RDIMMs with AMD EXPO and Intel XMP 3.0 profiles will be available in kits of up to 256 GB capacity and at speeds of up to 6400 MT/s.

Corsair's family of WS DDR5 RDIMMs includes 16 GB modules operating at up to 6400 MT/s with CL32 latency as well as 32 GB modules functioning at 5600 MT/s with CL40 latency. At present, Corsair offers a quad-channel 64 GB kit (4×16GB, up to 6400 MT/s), a quad-channel 128GB kit (4×32GB, 5600 MT/s), an eight-channel 128 GB kit (8×16GB, 5600 MT/s), and an eight-channel 256 GB kit (8×32GB, 5600 MT/s) and it remains to be seen whether the company will expand the lineup.

Corsair's WS DDR5 RDIMMs are designed for AMD's TRX50 and WRX90 platforms as well as Intel's W790 platform and are therefore compatible with AMD's Ryzen Threadripper Pro 7000 and 7000WX-series as well as Intel's Xeon W-2400/3400-series CPUs. The modules feature both AMD EXPO and Intel XMP 3.0 profiles to easily set their beyond-JEDEC-spec settings and come with thin heat spreaders made of pyrolytic graphite sheet (PGS), which thermal conductivity than that of copper and aluminum of the same thickness. For now, Corsair does not disclose which RCD and memory chips its registered memory modules use.

Unlike many of its rivals among leading DIMM manufacturers, Corsair did not introduce its enthusiast-grade RDIMMs when AMD and Intel released their Ryzen Threadripper and Xeon W-series platforms for extreme workstations last year. It is hard to tell what the reason for that is, but perhaps the company wanted to gain experience working with modules featuring registered clock drivers (RCDs) as well as AMD's and Intel's platforms for extreme workstations.

The result of the delay looks to be quite rewarding: unlike modules from its competitors that either feature AMD EXPO or Intel XMP 3.0 profiles, Corsair's WS DDR5 RDIMMs come with both. While this may not be important on the DIY market where people know exactly what they are buying for their platform, this is a great feature for system integrators, which can use Corsair WS DDR5 RDIMMs both for their AMD Ryzen Threadripper and Intel Xeon W-series builds, something that greatly simplifies their inventory management.

Since Corsair's WS DDR5 RDIMMs are aimed at workstations and are tested to offer reliable performance beyond JEDEC specifications, they are quite expensive. The cheapest 64 GB DDR5-5600 CL40 kit costs $450, the fastest 64 GB DDR5-6400 CL32 kit is priced at $460, whereas the highest end 256 GB DDR5-5600 CL40 kit is priced at $1,290.

Western Digital Previews 4 TB SD Card: World's Highest-Capacity

11 avril 2024 à 22:30

Western Digital this week is previewing the industry's first 4 TB SD card. The device is being showcased at the NAB trade show for broadcasters and content creators and will be released commercially in 2025.

Western Digital's SanDisk Extreme Pro SDUC 4 TB SD card complies with the Secure Digital Ultra Capacity standard (SDUC, which enables up to 128TB). The card uses the Ultra High Speed-I (UHS-I) interface and is rated for speed Class 10, therefore supporting a minimum speed of 10 MB/s and a maximum data transfer rate of 104 MB/s when working in UHS104 (SDR104) mode (there is a catch about performance, but more on that later). WD's SD card is also rated to meet Video Speed Class V30, supporting a minimal sequential write speed of 30 MB/s, which is believed to be good enough for 8K video recording, above and beyond the 4K video market that Western Digital is primarily aiming the forthcoming card at.

For now, Western Digital is not disclosing what NAND is in the SanDisk Extreme Pro SDUC 4 TB SD card. Given the high capacity and relatively distant 2025 release date, WD may be targetting this as one of their first products to use their forthcoming BiCS 9 NAND.

And while not listed in WD's official press release, we would be surprised if the forthcoming card didn't also support the off-spec DDR200/DDR208 mode, which allows for higher transfer rates than the UHS-I standard normally allows via double data rate signaling. Western Digital's current-generation SanDisk Extreme Pro SDXC 1 TB SD card already supports that mode, allowing it to reach read speeds as high as 170 MB/s, so it would be surprising to see the company drop it from newer products. That said, the catch with DDR208 remains the same as always: it's a proprietary mode that requires a compatible host to make use of.

Western Digital has not disclosed how much will its SanDisk Extreme Pro SDUC 4 TB SD card cost. A 1 TB SanDisk Extreme Pro card costs $140, so one can make guesses about the price of a 4 TB SD card that uses cutting-edge NAND.

AMD Quietly Launches Ryzen 7 8700F and Ryzen 5 8400F Processors

AMD has recently expanded its Ryzen 8000 series by introducing the Ryzen 7 8700F and Ryzen 5 8400F processors. Initially launched in China, these chips were added to AMD's global website, signaling they are available worldwide, apparently from April 1st. Built from the recent Zen 4-based Phoenix APUs using the TSMC 4nm node as their Zen 4 mobile chips, these new CPUs lack integrated graphics. However, the Ryzen 7 8700F does include the integrated Ryzen AI NPU for added capabilities in a world currently dominated by AI and moving it directly into the PC.

The company's decision to announce these chips in China aligns with its strategy to offer Ryzen solutions at every price point in the market. Although AMD didn't initially disclose the full specifications of these F-series models, and we did reach out to the company to ask about them, they refused to discuss them with us. Their listing on the website has now been updated with a complete list of specifications and features, with everything but the price mentioned.

The Ryzen 7 8700F features an 8C/16T design, with 16MB of L3 cache and the same 65W TDP as the Ryzen 7 8700G. Although the base clock speed is 4.1 GHz, it boosts to 5.0 GHz; this is 100 MHz less on both base/boost clocks than the 8700G. Meanwhile, the Ryzen 5 8400F is a slightly scaled-down version of the Ryzen 8600G APU, with 6C/12, 16MB of L3 cache, and again has a 100 MHz reduction to base clocks compared to the 8600G. Unlike the Ryzen 5 8400F, the Ryzen 7 8700F keeps AMD's Ryzen AI NPU, adding additional capability for generative AI. 

The Ryzen 5 8400F can boost up to 4.7 GHz, 300 MHz slower than the Ryzen 5 8600G. AMD also allows overclocking for these new F-series chips, which means users could potentially boost the performance of these processors to match their G-series equivalents.

Pricing details are still pending, but to remain competitive, AMD will likely need to price these CPUs below the 8700G and 8600G, as well as the Ryzen 7 7700 and Ryzen 5 7600. These CPUs offer, albeit very limited, integrated graphics and have double the L3 cache capacity, along with higher boost clocks than the 8000F series chips, so pricing is something to consider whenever pricing becomes available.

Intel Teases Lunar Lake At Intel Vision 2024: 100+ TOPS Overall, 45 TOPS From NPU Alone

11 avril 2024 à 17:00

During the main keynote at Intel Vision 2024, Intel CEO Pat Gelsinger flashed a completed Lunar Lake chip off, much like EVP and General Manager of Intel's Client Computing Group (CCG) Michelle Johnston Holthaus did back at CES 2024. The contrast between the two glimpses of the Lunar Lake chip is that Pat Gelsinger gave us something juicier than just a photo op. He clarified and claimed the levels of AI performance we can expect to see when Lunar Lake launches.

According to Intel's CEO Pat Gelsinger, Lunar Lake, scheduled to be launched towards the end of this year, is set to raise the bar even further regarding on-chip AI capabilities and performance. At Intel's own Vision event, aptly named Intel Vision, current CEO of Intel Pat Gelsinger stated during his presentation that Lunar Lake will be the 'flagship SoC' for the next generation of AI PCs. Intel claims that Lunar Lake will have 3X the AI performance of their current Meteor Lake SoC, which is impressive as Meteor Lake is estimated to be running around 34 TOPS combined with the NPU, GPU, and CPU.

Factoring in the NPU within Meteor Lake, 11 of the 34 TOPS come solely from the NPU. Still, Intel claims that the NPU on Lunar Lake will hit a large 45 TOPs, akin to the Hailo-10 add-in card and similar to Qualcomm's Snapdragon X Elite processor. Factoring in the integrated graphics and the compute cores, Intel is claiming a combined total of over 100 TOPS, and with Microsoft's self-imposed guidelines of what constitutes an 'AI PC' coming in at 40 TOPS, Intel's NPU fits the bill.

Intel also alludes to how they are gaining a load of TOPS performance from the NPU, whether that be with new technologies; the NPU will likely be built in a more advanced node, perhaps Intel 18A. Another thing Intel didn't highlight was how they were measuring the TOPS performance, whether that be INT8 or INT4.

Still, one thing is clear: Intel wants to increase on-chip AI capabilities in desktop PCs and notebooks with each generation. Intel is also attempting to leverage more AI performance to help boost its goal to ship 100 million AI PCs by the end of 2025. Intel has already announced that it's shipped 5 million thus far and plans to sell another 40 million units by the end of the year.

The Intel Core Ultra 7 155H Review: Meteor Lake Marks A Fresh Start To Mobile CPUs

11 avril 2024 à 12:30

One of the most significant talking points of the last six months in mobile computing has been Intel and their disaggregated Meteor Lake SoC architecture. Meteor Lake, along with the new Core and Core Ultra naming scheme, also heralds the dawn of their first tiled architecture for the mobile landscape on the latest Intel 4 node with Foveros packaging. In December last year, Intel unveiled their premier Meteor lake-based Core Ultra H series, with five SKUs ranging from two with 4P+8E+2LP/18T and three with 6P+8E+2LP/22T models. Since then, many vendors and manufacturers have launched notebooks capitalizing on Intel's latest multi-tiled Meteor Lake SoC architecture as the heart of power and performance, driving their latest models into 2024.

Today, we will focus on an attractive ultrabook via the ASUS Zenbook 14 OLED (UX3405MA), which features a thin and light design and is powered by Intel's latest Meteor Lake Core Ultra 7 155H processor. While much of the attention is going to come on how the Intel Core Ultra 7 155H with its 6P+8E+2LP/22T configuration and 8 Arc Xe integrated graphics cores will perform, the ASUS Zenbook 14 OLED UX3405MA has plenty of features within its sleek Ponder Blue colored shell to make it very interesting. Included is a 14" 3K (2880 x 1800) touchscreen OLED panel with a 120 Hz refresh rate, 32 GB of LPDDR5X memory (soldered), and a 1 TB NVMe M.2 SSD for storage.

Intel To Discontinue Boxed 13th Gen Core CPUs for Enthusiasts

11 avril 2024 à 00:00

In an unexpected move, Intel has announced plans to phase out the boxed versions of its enthusiasts-class 13th Generation Core 'Raptor Lake' processors. According to a product change notification (PCN) published by the company last month, Intel plans to stop shipping these desktop CPUs by late June. In its place will remain Intel's existing lineup of boxed 14th Generation Core processors, which are based on the same 'Raptor Lake' silicon and typically carry higher performance for similar prices.

Intel customers and distributors interested in getting boxed versions 13th Generation Core i5-13600K/KF, Core i7-13700K/KF, and Core i9-13900K/KF/KS 'Raptor Lake' processors with unlocked multiplier should place their orders by May 24, 2024. The company will ship these units by June 28, 2024. Meanwhile, the PCN does not mention any change to the availability of tray versions of these CPUs, which are sold to OEMs and wholesalers.

The impending discontinuation of Intel's boxed 13th Generation Core processors comes as the company's current 14th Generation product line, 'Raptor Lake Refresh' is largely a rehash of the same silicon at slightly higher clockspeeds. Case in point: all of the discontinued SKUs are based on Intel's B0 Raptor Lake silicon, which is still being used for their 14th Gen counterparts. So Intel has not discontinued producing any Raptor Lake silicon; only the number of retail SKUs is getting cut-down.

As outlined in our 14th Generation Core/Raptor Lake Refresh review, the 14th Gen chips largely make their 13th Gen counterparts redundant, offering better performance at every tier for the same list price. And with virtually all current generation motherboards supporting both generation of chips, apparently Intel feels there's little reason to keep around what's essentially older, slower SKUs of the same silicon.

Interestingly, the retirement of the enthusiast-class 13th Generation Core chips is coming before Intel discontinues their even older 12th Generation Core 'Alder Lake' processors. 12th Gen chips are still available to this day in both boxed and tray versions, and the Alder Lake silicon itself is still widely in use in multiple product families. So even though Alder Lake shares the same platform as Raptor Lake, the chips based on that silicon haven't been rendered redundant in the same way that 13th Gen Core chips have.

Ultimately, it would seem that Intel is intent on consolidating and simplifying its boxed retail chip offerings by retiring their near-duplicate SKUs. Which for PC buyers could present a minor opportunity for a deal, as retailers work to sell off their remaining 13th Gen enthusiast chips.
