Antec's 'Performance 1M' Mini-ITX Chassis Can House a GeForce RTX 4090

With the highly integrated nature of PCs these days, the Mini-ITX form-factor has become a very viable option for high-performance gaming system. With plenty of motherboards available for both AMD and Intel's latest platforms, equipping an ITX system with a CPU is easy enough. But the small size of the form factor means that housing an ultra-wide flagship-level graphics card remains an issue. For this year's Computex trade show, Antec was showing off their solution to the problem of giant video cards: the Performance 1M case, a Mini-ITX case with a separate chamber just for a large video card.

Antec's Performance 1M is a dual-chamber Mini-ITX chassis that splits off the video card from the rest of the system. The primary chamber houses a Mini-ITX motherboard and an SFX power supply, while the secondary chamber houses a huge graphics card. Notably, the two chambers are bridged using a PCIe riser cable, allowing the motherboard chamber to be far shorter than even a half-height PCIe card, while the video card chamber can hold a triple-slot video card parallel to the motherboard chamber, cutting down on wasted space. For Antec's Computex demo, the company had a triple-slot ASUS GeForce RTX 4090 installed to showcase how this worked.

Antec's decision to allocate most of the case's volume to th video card chamber does come with a slight catch, however: it doesn't leave much space for a CPU cooler in the motherboard chamber. The short motherboard chamber means that system builders will have to use a low-profile cooler; these are readily available, but it does leave less thermal headroom overall for high-end CPUs. So there are still trade-offs for being able to accommodate a high-end video card.

Otherwise, the Performance 1M chassis from Antec look very stylish and are traditionally well built from stainless steel and aluminum. The chassis can be equipped with two 120-mm or two 140-mm coolers for extra airflow (which will help performance), one 2.5-inch SATA SSD, and even some RGB bling. To make the PC built inside a Performance 1M case more convenient to use, there are two USB Type-C ports on the front.

Of course, housing a GeForce RTX 4090 graphics card in a Mini-ITX chassis has its peculiarities when it comes to dimensions and Antec's Performance 1M measures 424×175×260mm, which is pretty large. On the other hand, for an ultra-high-performance gaming system, this is pretty compact.

Antec's Performance 1M Mini-ITX chassis will be available in gunmetal gray and matte black colors sometimes later this year. Pricing is something that the company is thinking about now, though keep in mind that we are talking about unique premium products.

Realtek Outlines SSD Controller Roadmap: High-End PCIe 5.0 x4 Platform in the Works

While Realtek is best known in the enthusiast space for for its peripheral controllers such as audio codecs and network controllers, the company also has a small-but-respectable SSD controller business that tends to fly under the radar due to its focus on entry-level and mainstream drives. But Realtek's stature in the SSD space is on the rise, as the company is not only planning new PCIe Gen5 SSD controllers, but also their first high-end, DRAM-equipped SSD controller.

For this year's Computex trade show, Realtek laid out a new SSD controller roadmap that calls for the company to release a trio of new SSD controllers over the next couple of years. First up is a new four-channel entry-level PCIe 4.0 controller, the RTS5776DL, which will be joined a bit later by a PCIe 5.0 variant, the RTS5781DL. But most interesting on Realtek's new roadmap is the final chip being planned: the eight-channel, DRAM-equipped RTS5782, which would be the company's first high-end SSD controller, capable of hitting sequential read rates as high as 14GB/second.

4KB Random Write IOPS 2500k 1400k 1200k - -

Diving a bit deeper into Realtek's roadmap, the RTS5776DL is traditional DRAM-less PCIe Gen4 x4 controller with four NAND channels, and is aimed at entry-level drives. The controller's NAND support is quite modern, however, supporting the latest ONFI/Toggle standards, which will allow it to hit NAND transfer rates up to 3600 MT/second. Across four channels, that's enough bandwidth to fully saturate a PCIe 4.0 x4 connection with sequential read/writes, while random 4K IOPS can burst as high as 1.2 million. Engineering samples of the controller are set to emerge in Q4 2024, so do not expect actual drives based on this chip to emerge for sale until the second half of next year at the earliest.

Realtek is also preparing the RTS5781DL, which can be thought of as a PCIe 5.0 version of their DRAM-less controller platform. The RTS5781DL features the same four-channel NAND layout and 3600 MT/sec max NAND transfer rates, which with the additional bandwidth afforded by PCIe 5.0, shifts the performance bottleneck back to the NAND. Overall, Realtek expects drives with its first PCIe Gen5 SSD controller to hit sustained transfer rates up to 10GB/second, and up to 1.4 million random read/write IOPS. The company aims to make engineering samples of this controller available in the first quarter of 2025, so actual drives will hit the market in late 2025 at best.

Finally, the pinnacle of Realtek's roadmap will be its RTS5782, which is the company's first high-end SSD controller. Besides including support for on-drive DRAM (DDR4/LPDDR4X) for higher performance, the back-end of the RTS5782 will feature an eight NAND channel design that supports transfer rates up to 3600 MT/second. Drives built with the controller are expected to be able to sustain 14GB/second sequential read rates and 12GB/second sequential writes, while the 4K random IOPS performance jumps to 2.5 million 4K read and write IOPS.

Unfortunately, the RTS5782 is also the farthest out of the three controllers, as it's still in the planning stages at Realtek. Consequently, for the moment the company isn't offering any guidance on when the new controller will be ready. No doubt the company will have more to show off next year for Computex 2025.

Noctua Shows Off Thermosiphon Based CPU Cooler Prototype At Computex 2024

Many companies showed off a range of concept designs during Computex 2024, but perhaps Noctua had one of the coolest. Noctua, primarily known for its air coolers, had a pumpless prototype that showcased Thermisiphon cooling. It looks like a conventional AIO cooler on the surface but is much more efficient, cooler, and quieter than traditional water coolers.

Touching quickly on Thermosiphon cooling, it uses the natural laws of thermodynamics to use heat (the CPU) as a source to turn the liquid to the top, evaporating through the system. This evaporated liquid rises and is pushed into the condenser (radiator), which, in the case of Noctua's cooler, is cooled by fans and turned back into liquid, which then flows back toward the CPU. Not only does Theromsiphon technology use gravity to help aid the flow of liquid, but it is also a highly efficient way of distributing heat as vaporization can absorb heat better, and it doesn't feature any moving parts in the mechanism, aside from the fans, of course.

As with traditional AIO CPU coolers, Noctua's Thermosiphon design has a 240mm radiator with a pair of 120cm Noctua fans, which cools the vapor down and sends it back to the evaporator. While this isn't a new concept and vapor chamber cooling has been used for many years in CPUs and even laptop coolers, Thermosiphon is certainly a technology Noctua thinks it can leverage to ensure better cooling performance and robust reliability.

Speaking to Noctua at Computex 2024, they informed me of the benefits and pitfalls of the Thermosiphon technology. In terms of the pros, Thermosiphon cooling in itself has no moving parts, which not only improves reliability but also means there is less to go wrong. Another positive is that even the quietest AIO CPU coolers can be quite noisy, as the water pump that circulates the fluid can cause vibrations, which in turn makes noise. The biggest drawback of implementing Thermosiphon cooling for PCs is that conventional tubing can wear out over time. While adding metal tubing would last longer, it's not flexible, although Noctua said they have discussed this with system integrators.

Although Noctua's Thermosiphon is currently just a proof of concept and sis in the early development stage, there's no launch date or indication it will hit the market. It's an interesting design, and we hope it does eventually come to market.

The Qualcomm Snapdragon X Architecture Deep Dive: Getting To Know Oryon and Adreno X1

The curtains are drawn and it’s almost showtime for Qualcomm and its Snapdragon X SoC team. After first detailing the SoC nearly 8 months ago at the company’s most recent Snapdragon Summit, and making numerous performance disclosures in the intervening months, the Snapdragon X Elite and Snapdragon X Plus launch is nearly upon us. The chips have already shipped to Qualcomm’s laptop partners, and the first laptops are set to ship next week.

In the last 8 months Qualcomm has made a lot of interesting claims for their high-performance Windows-on-Arm SoC – many of which will be put to the test in the coming weeks. But beyond all the performance claims and bluster amidst what is shaping up to be a highly competitive environment for PC CPUs, there’s an even more fundamental question about the Snapdragon X that we’ve been dying to get to: how does it work?

Ahead of next week’s launch, then, we’re finally getting the answer to that, as today Qualcomm is releasing their long-awaited architectural disclosure on the Snapdragon X SoC. This includes not only their new, custom Arm v8 “Oryon” CPU core, but also technical disclosures on their Adreno GPU, and the Hexagon NPU that backs their heavily-promoted AI capabilities. The company has made it clear in the past that the Snapdragon X is a serious, top-priority effort for the company – that they’re not just slapping together a Windows SoC from their existing IP blocks and calling it a day – so there’s a great deal of novel technology within the SoC.

And while we’re excited to look at it all, we’ll also be the first to admit that we’re the most excited to finally get to take a deep dive on Oryon, Qualcomm’s custom-built Arm CPU cores. The first new high-performance CPU design created from scratch in the last several years, the significance of Oryon cannot be overstated. Besides providing the basis of a new generation of Windows-on-Arm SoCs that Qualcomm hopes will vault them into contention in the Windows PC marketplace, Oryon will also be the basis of Qualcomm’s traditional Snapdragon mobile handset and tablet SoCs going forward.

So a great deal of the company’s hardware over the next few years is riding on this CPU architecture – and if all goes according to plan, there will be many more generations of Oryon to follow. One way or another, it’s going to set Qualcomm apart from its competitors in both the PC and mobile spaces, as it means Qualcomm is moving on from Arm’s reference designs, which by their very nature are accessible Qualcomm’s competition as well.

So without further ado, let’s dive in to Qualcomm’s Snapdragon X SoC architecture.

Samsung Foundry Unveils Updated Roadmap: BSPDN and 2nm Evolution Through 2027

Samsung this week has unveiled its latest process technologies roadmap at the company's Samsung Foundry Forum (SFF) U.S. The new plan covers the evolution of Samsung's 2nm-class production nodes through 2027, including a process technology with a backside power delivery, re-emphasizing plans to bring out a 1.4nm-class node in 2027, and the introduction of a 'high value' 4nm-class manufacturing tech.

Samsung Foundry's key announcements for today are clearly focused on the its 2nm-class process technologies, which are set to enter production in 2025 and will span to 2027, when the company's 1.4-nm class production node is set to enter the scene. Samsung is also adding (or rather, renaming) another 2nm-class node to their roadmap with SF2, which was previously disclosed by Samsung as SF3P and aimed at high-performance devices.

"We have refined and improved the SF3P, resulting in what we now refer to as SF2," a Samsung spokesperson told AnandTech. "This enhanced node incorporates various process design improvements, delivering notable power, performance, and area (PPA) benefits."

This is another example of a rebranding of leading-edge fabrication nodes in the recent years by a major chipmaker. Samsung Foundry is not disclosing any specific PPA improvements SF3P has over SF2, and for now is only stating in high-level terms that it will be a better-performing node than the planned SF3P.

Meanwhile, this week's announcement also includes new information on Samsung's next batch of process nodes, which are planned for 2026 and 2027. In 2026 Samsung will have SF2P, a further refinement of SF2 which incorporates 'faster' yet less dense transistors. That will be followed up in 2027 with SF2Z, which adds backside power delivery to the mix for better and higher quality power delivery. In particular, Samsung is targetting voltate drop (aka IR drop) here, which is an ongoing concern in chip design.

Finally, SF1.4, a 1.4nm-class node, is on track for 2027 as well. Interestingly, however, it looks like it does not feature a backside power delivery. Which, per current roadmaps, would have Samsung as the only foundry not using BSPDN for their first 1.4nm/14Å-class node.

"We have optimized BSPDN and incorporated it for the first time in the SF2Z node we announced today," the spokesperson told us. "We will continue to refine this technology and apply it to future nodes, but we don't have a specific timeline to share at this time."

When compared to other contract fabs, Samsung's roadmap is now roughly in line with the rest in regards to 'nanometer' designations. Though absent further technical disclosures from Samsung, it remains unclear what the actual benefits will be for each node and how they compare to their predecessors, let alone how they'll compare to Intel Foundry and TSMC.

Report: MediaTek Working on Arm-Based Processor for Windows PCs

As Qualcomm's exclusivity for Arm-powered processors for Windows PCs is reportedly coming to its end, other chipmakers are getting ready to offer their Arm-based system-on-chips for Windows computers. And, according to a new report from Reuters, MediaTek will be among the companies jumping into the Windows-on-Arm field, with plans to launch their first PC processor late next year.

MediaTek's system-on-chip for Windows PCs will rely on Arm's 'ready-made designs,' according to Reuters. Which in turn hints that MediaTek would be using Arm's compute sub-system (CSS) for client PCs, a building block designed to significantly speed up development of SoCs.

With the vauge nature of the Reuters report, however, which version of Arm's IP MediaTek might be using remains unclear, and the answer to that will largely hinge on timing. Arm refreshes its client cores and IP offerings yearly – typically announcing them to the public in May – with finished chips rolling out as early as later in the year. So depending on just how late in the year MediaTek is planning to launch their chip, the company has a large enough window to potentially use either the current 2024 client designs, or next year's 2025 designs.

For reference, Arm's 2024 CSS for client systems is quite powerful on its own. It includes two ultra-high-performance Arm Cortex-X925 cores (each with up to 3MB L2 cache and clock speeds over 3.60 GHz, supporting SVE and SVE2), four high-performance Cortex-A725 cores, two energy-efficient Cortex-A520 cores, and an Immortalis-G925 graphics processor. And, of course, MediaTek has the expertise to skip Arm's CSS and build their own bespoke designs as well, if that's what they'd prefer.

Overall, the latest client designs from Arm can accommodate up to 14 CPU cores – Arm intentionally leaves headroom for designs to be scaled-up for laptops – which would make for quite a formidable chip. But the PC SoC market has no shortage of capable contenders with their own designs; besides Qualcomm's Snapdragon X processors, MediaTek would also be going up against the latest designs from Intel and AMD. All of whom are planning to make big plays for the mobile PC market in the next several months. So MediaTek will need to make a serious effort if their effort to jump into the PC SoC market are to succeed.

Since 2016, Microsoft has partnered with Qualcomm to bring Arm's processor architecture, which is widely used in smartphones, to Windows PCs. Qualcomm has an exclusive agreement to supply these chips for the next several months (the exact timing remains unclear), after which other designers like MediaTek can enter the market. Qualcomm, for its part, has benefited greatly from collaborating with Microsoft, so it will be interesting to see if Microsoft extends a similar hand out to other Arm chip makers.

Ultimately, the market for Arm PC SoCs has the potential to get crowded quickly. According to previous reports from Reuters, both AMD and NVIDIA are also developing Arm-based chips for Windows. So if all of those projects come to fruition, there could potentially be several Arm SoCs available to PC manufacturers around the same time. All of which would be a massive change from the past 20 years of the PC, where Intel and AMD have been the entire market.

Both MediaTek and Microsoft have declined to comment on the ongoing developments, the news agency states.

ASMedia Preps USB4 v2 Controller and PHY

The USB Implementers Forum (USB-IF) introduced USB4 version 2.0 in fall 2022, and it expects systems and devices with the tech to emerge later this year and into next year. These upcoming products will largely rely on Intel's Barlow Ridge controller, a full-featured Thunderbolt 5 controller that goes above and beond the baseline USB4 v2 spec. And though extremely capable, Intel's Thunderbolt controllers are also quite expensive, and Barlow Ridge isn't expected to be any different. Fortunately, for system and device vendors that just need a basic USB4 v2 solution, ASMedia is also working on its own USB4 v2 controller.

At Computex 2024, ASMedia demonstrated a prototype of its upcoming USB4 v2 physical interface (PHY), which will support USB4 v2's new Gen 4 (160Gbps) data rates and the associated PAM-3 signal encoding. The prototype was implemented using an FPGA, as the company yet has to tape out the completed controller.

Ultimately, the purpose of showing off a FPGA-based PHY at Computex was to allow ASMedia to demonstrate their current PHY design. With the shift to PAM-3 encoding for USB4 v2, ASMedia (and the rest of the USB ecosystem) must develop significantly more complex controllers – and there's no part of that more critical than a solid and reliable PHY design.

As part of their demonstration, ASMedia had a classic eye diagram display. The eye diagram demoed has a clear opening in the center, which is indicative of good signal integrity, as the larger the eye opening, the less distortion and noise in the signal. The horizontal width of the eye opening represents the time window in which the signal can be sampled correctly, so the relatively narrow horizontal spread of the eye opening suggests that there is minimal jitter, meaning the signal transitions are consistent and predictable. Finally, the vertical height of the eye opening indicates the signal amplitude and the rather tall eye opening suggests a higher signal-to-noise ratio (SNR), meaning that the signal is strong compared to any noise present.

ASMedia itself is one of the major suppliers for discrete USB controllers, so the availability of ASMedia's USB4 v2 chip is crucial for adoption of the standard in general. While Intel will spearhead the industry with their Barlow Ridge Thunderbolt 5/USB4 v2 controller, ASMedia's controller is poised to end up in a far larger range of devices. So the importance of the company's USB4 v2 PHY demo is hard to overstate.

Demos aside, ASMedia is hoping to tape the chip out soon. If all goes well, the company expects their first USB4 v2 controllers to hit the market some time in the second half of 2025.

Qualcomm: Some Snapdragon X Elite Laptops Will Come with 5G Modems

One of Qualcomm's indisputable strengths are its 5G modems – something which even Apple has yet to successfully ween itself from. And while Qualcomm is not integrating a modem into its first-generation Oryon-based Snapdragon X chips, the company is still looking to leverage that technology advantage via discrete modems that can be installed in Snapdragon X laptops.

To date, Qualcomm has won 23 laptop designs with its Snapdragon X Elite SoCs, and all of the leading PC vendors have introduced systems based on Qualcomm's Snapdragon X Elite processors. However, only some of them will be equipped with modems, the company detailed at Computex 2024.

While the technical rationale for this is very straightforward (not every vendor wants to buy and dedicate the space to modems), it's still a bit of a surprise in as much as Qualcomm has traditionally heavily pushed laptop vendors to include their modems. But as the Snapdragon X has entered the picture, the joint Qualcomm/Microsoft always connected PC (ACPC) initiative is taking a back seat – meaning modems are no longer being pushed nearly as hard. In its place, the two companies have pivoted hard to equipping mainstream systems with the hardware needed for local AI processing (i.e. NPUs), and with it, Microsoft's Copilot+ PC branding.

Laptop manufacturers, in the meantime, are breathing a sigh of relief, as this switch to emphasizing AI comes at a much lower hardware cost, since vendors don't need to buy additional discrete hardware. Qualcomm for its part has never fully disclosed the full cost of including a Snapdragon modem with a laptop, but the total cost adds up quickly. Besides buying a discrete modem, device manufacturers also need to buy and integrate a 5G-capable radio frequency front end module (RF FEM), as well as the all-important antenna. And mmWave support of any kind can add another wrinkle, as multiple antennas at different orientations are needed to get the best results.

And while not said out-loud, Qualcomm's premium positioning strategy for 8cx-based laptops has not paid significant dividends. Snapdragon X laptops are being priced much more competitively, as Qualcomm is aiming to capture a meaningful share of the PC market – and high-cost features like modems would drive up the final price tag.

Still, virtually all Qualcomm representatives I talked to at Computex were happy to argue that an integrated modem is a huge benefit for their PCs, as they can get fast connectivity almost everywhere in the world instantly and not depend on Wi-Fi or even their smartphones. So the dream of widespread 5G-capable laptops is not dead at Qualcomm; it may just be delayed. In the meantime, for laptop buyers that do need or want a 5G modem, there will still be at least a few premium laptop models on store shelves with the necessary hardware.

No, It Does Not Fly: Corsair Demos '9000D Airflow' PC Case with 24 Fans

Trade shows like Computex always bring out their fair share of oddities, and this year was no exception, with one of the highlights being a Corsair PC case with no fewer than 24 fans.

As one of a handful of companies offering really big desktop PC cases, Corsair was demonstrating its new creature: the 9000D Airflow. At 90 liters in volume – which is twice the size of regular PCs and 1.5x the volume of a typical car gas tank – the colossal case is bigger than ever. It's so big, in fact, that it can house two systems: a full-size ATX (or smaller) system, as well as a separate Mini-ITX system.

The most eye-catching aspect of this PC case (besides its large size, of course) is that it can house as many as 22 fans in addition to two liquid cooling systems. As the name of the 9000D Airflow implies, all of those fans are meant to create as much airflow as possible. And yet, because there are so many fans inside, they do not have to run at a high RPM to move the requisite amount of air, so the 9000D Airflow is quieter than its size otherwise lets on.

To simplify installation of all these fans, the chassis consists of adjustable mounting points on a sliding rail, making the case versatile for any build requirements. The 9000D includes two InfiniRail systems, one at the top (holding six fans) and one at the front, each capable of holding up to eight 120mm fans. Adding fans on the sides and rear increases the total to 24. For those using 140mm or 200mm fans, the InfiniRails can be adjusted by unscrewing and repositioning them based on marked guidelines, allowing for a customized setup despite fitting fewer larger fans. The flexibility of the InfiniRail system enables unique fan placement, enabling the freedom to tailor the cooling configuration to specific needs.

The case design also includes 30mm of clearance behind the motherboard for efficient cable management, making it well-suited for creating clean, organized, and powerful builds.

Besides its may fans, the 9000D Airflow also offers 11 drive bays, plenty of front I/O ports (four USB Type-A, two USB Type-C, audio connectors) with RGB lighting controlled through the iCue Link system. The spacious design allows for comprehensive component compatibility and expansion.

Corsair's Airflow 9000D will be available later this year.

Cheaper PCIe 5.0 x4 SSDs Incoming: Silicon Power Demos Phison E31T-Based SSD

Although consumer SSDs based on Phison's PS5026-E26 controller have been on the market for almost a year and a half now, the class-leading drives still carry a distinct price premium, and to some degree that's because it's still one of the only options for a PCIe 5.0 SSD. But it looks like the situation is going to change in the coming quarters, as SSDs based on Phison's PS5031-E31T controller are incoming, with at least one Phison customer demoing an E31T drive on the Computex show floor.

Phison's PS5031-E31T controller uses two Arm Cortex-R5 cores accelerated by the Andes N25 CoXProcessor, just like its bigger brother Phison PS5026-E26. But this is where their major hardware similarities seem to end. The new E31T controller is a DRAM-less controller with four NAND channels (16 CE targets) that is produced on one of TSMC's 7nm processes, whereas the E26 is an eight-channel controller made on TSMC's 12nm production node.

Besides cutting down on memory channels and the use of DRAM to drive down costs, the E31T also picks up a couple of new tricks by virtue of being nearly two years newer. In particular, the E31T sports Phison's 7th Generation LDPC error correction technology, as opposed to the E25's 5th-gen LDPC

4KB Random Write IOPS 1500k 1200k 800k 2000k 1000k

Phison itself calls its E31T platform 'the first mainstream 10 GB/s platform,' which pretty much gives a performance indicator for some of the upcoming inexpensive PCIe Gen5 SSDs. As for random performance, we are talking about 1.5M IOPS per second, which is in line with performance offered by some of enterprise-grade PCIe Gen4 SSDs.

Meanwhile, a Silicon Power ad at Computex indicates that that the company at least hopes to get to 12 GB/sec with its "US85" drive. Which at 4 NAND channels would require pairing up the controller with cutting-edge 3200 MT/sec NAND. It's a bit of an odd pairing given the mainstream, cost-conscious status of the E31T controller, but then the savings on the controller supporting DRAM can be invested back into the NAND on the drive itself. And more importantly, with 12 GB/sec reads and writes, Silicon Power's US85 SSD will be able to compete against earlier E26-based drives that are still being sold on the market, which brings this product to a whole new level. Though Silicon Power will have to be able to procure enough fast 3D NAND to meet demand.

Both Phison and Silicon Power expect E31T to start shipping in Q4, so by the start of next year, mainstream SSDs should be receiving a nice speed boost.

SK hynix: GDDR7 Mass Production To Start in Q4'2024

Update 06/13: SK hynix has sent a note to AnandTech clarifying that the company "plans to start mass production of GDDR7 in the fourth quarter of this year when the relevant market opens up." This article has been updated accordingly.

Being a major JEDEC memory standard, GDDR7 is slated to be produced by all three of the Big Three memory manufacturers. But it seems that not all three vendors will be kicking off mass production at the same time.

SK hynix was at this year's Computex trade show, showing off their full lineup of memory technologies – including, of course, GDDR7. SK hynix is the last of the major memory vendor's we've seen promoting their memory, and fittingly, they seem to be the last in terms of their mass production schedule. According to company representatives, the firm will kick off mass production of their GDDR7 chips in the last quarter of 2024.

Comparatively, the company's cross-town rival, Samsung, is already sampling memory with the goal of getting it out the door in 2024. And Micron has been rather gung ho about not only starting mass production this year, but starting it early enough that at least some of their customers will be able to ship finished products this year.

That said, it bears mentioning that with industry-standard memory technologies, mass production at one vendor does not indicate that another is late; it is just indicating that someone was first to validate with a partner and that partner plans to ship its product in 2024. And while mass production remains another 4+ months out, SK hynix does have sample chips for its partners to test right now, and the chips have been demonstrated at Computex.

As far as SK hynix's floor booth at Computex 2024 is concerned, the company had GDDR7 chips on display along with a table essentially summarizing the company's roadmap. For now, SK hynix is planning on both 16Gbit and 24Gbit chips, with data transfer rates of up to 40 GT/s. Though when SK hynix intends to launch their higher-end configurations remains to be seen. Both of the company's rivals are starting out with 16Gbit chips running at 32 GT/sec, so being the first to get a faster/larger chip out would be a feather in SK hynix's cap.

Micron's GDDR7 Chip Smiles for the Camera as Micron Aims to Seize Larger Share of HBM Market

UPDATE 6/12: Micron notified us that it expects its HBM market share to rise to mid-20% in the middle of calendar 2025, not in the middle of fiscal 2025.

For Computex week, Micron was at the show in force in order to talk about its latest products across the memory spectrum. The biggest news for the memory company was that it has kicked-off sampling of it's next-gen GDDR7 memory, which is expected to start showing up in finished products later this year and was being demoed on the show floor. Meanwhile, the company is also eyeing taking a much larger piece of the other pillar of the high-performance memory market – High Bandwidth Memory – with aims of capturing around 25% of the premium HBM market.

GDDR7 to Hit the Market Later This Year

Micron's first GDDR7 chip is a 16 Gb memory device with a 32 GT/sec (32Gbps/pin) transfer rate, which is significantly faster than contemporary GDDR6/GDDR6X. As outlined with JEDEC's announcement of GDDR7 earlier this year, the latest iteration of the high-performance memory technology is slated to improve on both memory bandwidth and capacity, with bandwidths starting at 32 GT/sec and potentially climbing another 50% higher to 48 GT/sec by the time the technology reaches its apex. And while the first chips are starting off at the same 2GByte (16Gbit) capacity as today's GDDR6(X) chips, the standard itself defines capacities as high as 64Gbit.

Of particular note, GDDR7 brings with it the switch to PAM3 (3-state) signal encoding, moving from the industry's long-held NRZ (2-state) signaling. As Micron was responsible for the bespoke GDDR6X technology, which was the first major DRAM spec to use PAM signaling (in its case, 4-state PAM4), Micron reckons they have a leg-up with GDDR7 development, as they're already familiar with working with PAM.

The GDDR7 transition also brings with it a change in how chips are organized, with the standard 32-bit wide chip now split up into four 8-bit sub-channels. And, like most other contemporary memory standards, GDDR7 is adding on-die ECC support to hold the line on chip reliability (though as always, we should note that on-die ECC isn't meant to be a replacement for full, multi-chip ECC). The standard also implements some other RAS features such as error checking and scrubbing, which although are not germane to gaming, will be a big deal for compute/AI use cases.

The added complexity of GDDR7 means that the pin count is once again increasing as well, with the new standard adding a further 86 pins to accommodate the data transfer and power delivery changes, bringing it to a total of 266 pins. With that said, the actual package size is remaining unchanged from GDDR5/GDDR6, maintaining that familiar 14mm x 12mm package. Memory manufacturers are instead using smaller diameter balls, as well as decreasing the pitch between the individual solder balls – going from GDDR6's 0.75mm x 0.75mm pitch to a slightly shorter 0.75mm x 0.73mm pitch. This allows the same package to fit in another 5 rows of contacts.

As for Micron's own production plans, the company is using its latest 1-beta (1β) fabrication process. While the major memory manufacturers don't readily publish the physical parameters of their processes these days, Micron believes that they have the edge on density with 1β, and consequently will be producing the densest GDDR7 at launch. And, while more nebulous, the company company believes that 1β will give them an edge in power efficiency as well.

Micron says that the first devices incorporating GDDR7 will be available this year. And while video card vendors remain a major consumer of GDDR memory, in 2024 the AI accelerator market should not be overlooked. With AI accelerators still bottlenecked by memory capacity and bandwidth, GDDR7 is expected to pair very well with inference accelerators, which need a more cost-effective option than HBM.

Micron Hopes to Get to Mid-20% HBM Market Share with HBM3E

Speaking of HBM, Micron was the first company to formally announce its HBM3E memory last year, and it was among the first to start its volume shipments earlier this year. For now, Micron commands a 'mid-single digit' share of this lucrative market, but the company has said that it plans to rapidly gain share. If all goes well, by the middle of its calendar 2025 (i.e., the end of calendar Q1 2025) the company hopes to capture a mid-20% share of the HBM market.

"As we go into fiscal year 2025, we expect our share of HBM to be very similar to our overall share on general DRAM market," said Praveen Vaidyanathan, vice president and general manager of the Compute Products Group at Micron. "So, I would say mid-20%. […] We believe we have a very strong product as [we see] a lot of interest from various GPU and ASIC vendors, and continuing to engage with customers […] for the next, say 12 to 15 months."

When asked whether Micron can accelerate output of HBM3E at such a rapid pace in terms of manufacturing capacity, Vaidyanathan responded that the company has a roadmap for capacity expansion and that the company would meet the demand for its HBM3E products. 

ASRock Unveils Motherboards For Ryzen 9000 At Computex 2024: X870E Taichi and X870E Taichi Lite

During Computex 2024, ASRock held an event to unveil some of its upcoming X870E motherboards, designed for AMD's Zen 5-based Ryzen 9000 series processors. ASRock's announcement includes a pair of Taichi-branded boards, the X870E Taichi and the lighter X870E Taichi lite, which uses AMD's X870E (Promontory 21) chipset for AM5.

The current flagship model announced from ASRock's X870E line-up for Ryzen 9000 is the ASRock X870E Taichi. ASRock is advertising a large 27-phase power delivery through 110A SPS, suggesting this board is designed for overclockers and all-around power users. Two PCIe 5.0 x16 slots (operating in either x16/x0 or x8/x8) provide high-speed bandwidth for cutting-edge graphics cards and other devices. Meanwhile, ASRock has gone with 4 DIMM slots on this board, so system builders will be able to max out the board's memory capacity at the cost of bandwidth.

The storage offering is impressive; besides the obligatory PCIe Gen5 x4 M.2 slot (Blazing M.2), ASRock has outfit the board with another three PCIe Gen4 x4 (Hyper) M.2 slots. Also present are two USB4 Type-C ports for high-bandwidth external I/O, while networking support is a solid pairing of a discrete Wi-Fi 7 controller with a Realtek 5Gb Ethernet controller (and the first AM5 board we've come across with something faster than a 2.5GbE controller).

The audio setup includes a Realtek ALC4082 codec and ESS SABRE9218 DAC supporting high-fidelity sound. The BIOS flashback feature is also a nice touch, and we believe this should be a feature on all mid-range to high-end motherboards, which provides an easy way to update the firmware without installing a CPU. And, as no high-end board would be complete without it, ASRock has put RGB lighting on the X870E Taichi as well.

Ultimately, as ASRock's high-end X870E board, the X870E Taichi comes with pretty much every last cutting-edge technology that ASRock can fit on the board.

Comparatively, the ASRock X870E Taichi Lite is a more streamlined and functional version of the X870E Taichi. The Lite retaining all of the latter's key features, including the 27-phase power delivery with 110A smart power stages, dual PCIe 5.0 x16 slots operating at x16 or x8/x8, four DDR5 DIMM slots, and four M.2 slots (1x Gen5 + 3x Gen4). The only significant difference is aesthetics: the Taichi Lite features a simpler silver-themed design without the RGB lighting, while the standard Taichi has a more intricate gold-accented and fanciful aesthetics.

In terms of availability, ASRock is not disclosing a release date for the board at the show. And, checking around with other tech journalists, Andreas Schilling from HawrdwareLUXX has heard that X870E and X870 motherboards aren't expected to be available in time for the Ryzen 9000 series launch. We will investigate this and contact the motherboard vendors to confirm the situation. Though as X870E/X870 boards barely differ from the current crop of X670E/B650E boards to begin with, the Ryzen 9000 series won't be fazed by a lack of slightly newer motherboards.

XPG Demos "Nia" Handheld Gaming PC With Foveated Rendering, Swappable DRAM

With the rise of the handheld gaming PC market, we've seen PC vendors and their partners toy with a number of tricks and tweaks to improve improve framerates in games, with some of their latest efforts on display at this year's Computex trade show. Perhaps the most interesting find thus far comes from ADATA sub-brand XPG, who is demoing their prototype "Nia" handheld PC, which uses eye tracking and dynamic foveated rendering to further improve their rendering performance.

For those unfamiliar, dynamic foveated rendering is a graphics technique that is sometimes used to boost performance in virtual reality (VR) and augmented reality (AR) applications by taking advantage of how human vision works. Typically, humans can only perceive detailed imagery in the relatively small central area of our vision called the fovea, while our peripheral vision is much less detailed. Dynamic foveated rendering, in turn, exploits this by using real-time eye tracking to determine where the user is looking, and then rendering just that area in high/full resolution, while rendering the peripheral areas in lower resolution. The net result is that only a fraction of the screen is rendered at full detail, which cuts down on the total amount of rendering work required and boosting framerates on performance-limited devices.

As stated before, this technology is sometimes used in high-end AR/VR headsets, where high resolution displays are placed mere inches from one's face. This ends up being an ideal use case for the technique, since at those distances, only a small fraction of the screen is within the fovea.

Using dynamic foveated rendering for a handheld, on the other hand, is a more novel application. All of the same visual principles apply, but the resolutions at play are lower, and the screen is farther from the users' eyes. This makes a handheld device a less ideal use case, at least on paper, as a larger portion of the screen is going to be in the fovea, and thus will need to be rendered at full resolution. None the less, it will be interesting to see how XPG's efforts pan out, and if dynamic foveated rendering is beneficial enough for handheld PCs. As we sometimes see with trade show demos, not everything makes it out of the prototype stage.

According to a press release put out by ADATA ahead of the trade show, the eye tracking technology is being provided by AMD collaborator Eyeware. Notably, their software-based approach runs on top of standard webcams, rather than requiring IR cameras. So the camera hardware itself should be pretty straight-forward.

Foveated rendering aside, XPG is making sure that the Nia won't be a one-trick pony. The handheld's other major claim to fame is its hardware swappability. The prototype handheld not only features a removable M.2-2230 SSD, but the company is also taking advantage of the recently-introduced LPCAMM2 memory module standard to introduce removable DRAM. Via a hatch in the back of the handheld, device owners would be able to swap out LPCAMM2 LPDDR5X modules for higher capacity versions. This would give the handheld an additional degree of future-proofness over current handhelds, which use non-replaceable soldered-down memory.

Rounding out the package, the current prototype is based on an AMD's Zen 4 Phoenix APU, which is used across both of the company's current mobile lines (Ryzen Mobile 7000/8000 and Ryzen Z1). Meanwhile, the unit's display is adjustable, allowing it to be angled away from the body of the handheld.

Assuming all goes well with the prototype, XPG aims to release a finished product in 2025.

G.Skill Demonstrates DDR5-10600 Memory Modules On Ryzen 8500G System

Ultra-high performance memory modules are a staple of of Computex, and it looks like this year G.Skill is showing off the highest performance dual-channel memory module kit to date. The company is demonstrating a DDR5 kit capable of 10,600 MT/s data transfer rate, which is a considerably higher speed compared to memory modules available today.

The dual-channel kit that G.Skill is demonstrating is a 32 GB Trident Z5 RGB kit that uses cherry-picked DDR5 memory devices and which can work in a DDR5-10600 mode with CL56 62-62-126 timings at voltages that are way higher than standard. The demoed DIMMs are running the whole day in a fairly warm room, though it does not really run demanding applications or stress tests.

Traditionally, memory module makers like G.Skill use Intel processors to demonstrate their highest-performing kits. But with the DDR5-10600 kit, the company uses AMD's Ryzen 5 8500G processor, which is a monolithic Zen 4-based APU with integrated graphics that's normally sold for budget systems. The motherboard is a high-end Asus ROG Crosshair X670E Gene and the APU is cooled down using a custom liquid cooling system The Asus ROG Crosshair X670E Gene motherboard has only two memory slots, which greatly helps to enable high data transfer rates, so it is a very good fit for the DDR5-10600 dual-channel kit.

Though I have sincere doubts that someone is going to use an ultra-expensive DDR5-10600 memory kit and related gate with this inexpensive processor, it is interesting (and unexpected) to see an AMD APU as a good fit to demonstrate performance potential of G.Skill's upcoming modules.

Speaking of availability of G.Skill's DDR5-10600 memory, it does not look like this kit is around the corner. The fastest DDR5 kit that G.Skill has today is its DDR5-8400 offering, so the DDR5-10600 will come to market a few speed bins later as G.Skill certainly needs to test the kit with various CPUs and ensure its stability. 

One other thing to keep in mind is that both AMD and Intel are about to release new desktop processors this year, with the Ryzen 9000-series and Arrow Lake processors respectively. So G.Skill will undoubtedly focus on tuning its DDR5-10600 and other high-end kits primarily with those new CPUs.

Update on Intel's Panther Lake at Computex 2024, Intel Powering Up Intel 18A Wafer Next Week

During the Intel keynote hosted by CEO Pat Gelsinger, he gave the world a glimpse into the Intel Client roadmap until 2026. Meteor Lake launched last year on that roadmap, and Lunar Lake, which we dived into yesterday as Intel disclosed technical details about the upcoming platform. Pat also presented a wafer on stage, Panther Lake, and he gave some additional information about Intel's forthcoming Panther Lake platform, which is expected in 2025.

We covered Intel's initial announcement about the Panther Lake platform last year. It is set to be Intel's first client platform using its Intel 18A node. Aside from once again affirming that things are on track for a 2026 launch, Pat Gelsinger, Intel's CEO, also confirmed that they will be powering on the first 18A wafer for Panther Lake as early as next week.

One element to consider from last year is that Lunar Lake is built using TSMC, with the Lunar Lake compute tile with Xe2-LPG graphics on TSMC N3B, and the I/O tile on TSMC N6. Pat confirmed on stage that Panther Lake will be on Intel 18A. Still, he didn't confirm whether the chip will be made purely at Intel, or a mix between Intel and external foundries (ala Meteor Lake). Intel has also yet to confirm the CPU cores to be used, but from what our sources tell us, it sounds like it will be the new Cougar Cove and Darkmont cores.

As we head into the second half of 2024 and after Lunar Lake launches, Intel may divulge more information, including the architectural advancements Panther Lake is expected to bring. Until then, we will have to wait and see.

Frore Demos Solid-State AirJet Cooler in Action: Significantly Improving Both Laptop and SSD Performance

In recent months, Frore Systems has been turning heads with their fanless solid-state air cooler technology. The AirJet, as it's come to be called, was previously shown off at CES this year; and for Computex, the company is back with a fresh round of demonstrations.

For the show, Frore has a number of demonstrations running in a fairly large showroom. The company is looking to address a wide range of products, from tablets to notebooks to small PCs, as well as embedded tablets. But there were two showcases in particular that caught my immediate attention: a Samsung Galaxy Book with and without Frore's AirJet, and an 8 TB Sabrent SSD in an external enclosure.

The Samsung Galaxy Book 2 Pro is an ultra-thin notebook that is normally cooled by a fan that, as argued by Flore, does not do its job properly. According to the company, the stock laptop only has enough cooling capacity to sustain 12W heat/power before it hits Tmax, whereas a retrofitted version with Frore's AirJet installed allows it to hold steady-state operation at 16W – and consequently delivering higher performance. In terms of Cinebench R23 multi-threaded results, we are talking about 5330 points for the modded notebook, versus 4255 for the off-the-shelf Galaxy Book 2 Pro.

The potential use cases for Frore Systems's AirJet solid-state cooling technology do not end with CPUs, either. As mentioned previously, the company is also demonstrating the AirJet Mini on Sabrent 8TB SSDs in Orico external enclosures, showcasing the advantage of the silent active cooler over passive cooling. The passively-cooled drive reached 62°C and leveled out at 1,320 MB/s due to thermal throttling. In contrast, the AirJet-cooled drive maintained a temperature of 42°C and achieved a considerably higher performance of 3,016 MB/s.

According to Frore, this significant improvement in both temperature and performance has already led to one major external SSD vendor adopting AirJet technology to improve the performance of their drives. Unfortunately, Frore isn't naming any names, only stating that it's a "big name."

Now, Frore's AirJet Mini and Mini Slim coolers can dissipate up to 5W of power each, and can be combined in to larger blocks of up to 5 coolers (we are talking about announced solutions, technologically scaling could he higher, but this is an entirely different conversation). So the technology does have some scalability limitations that makes it best-suited for lower-power devices. None the less, removing 25W of thermal energy from a modern laptop without a fan can make a huge difference in the performance of these normally passively-cooled devices.

Of course, the main goal for these Computex demos is far more than just showing off AirJets to the public; what Frore would really like to do is to land a deal for its solid-state cooling solution with a major PC vendor (e.g., Apple, Samsung, etc.). Though to do that, Frore has to pass qualification tests and ensure availability of its products, which is something the company says it's currently working on. Meanwhile, from performance point of view, especially given their dimensions, AirJets look very impressive.

Intel Unveils Lunar Lake Architecture: New P and E cores, Xe2-LPG Graphics, New NPU 4 Brings More AI Performance

Intel this morning is lifting the lid on some of the finer architectural and technical details about its upcoming Lunar Lake SoC – the chip that will be the next generation of Core Ultra mobile processors. Once again holding one of their increasingly regular Tech Tour events for media and analysts, Intel this time set up shop in Taipei just before the beginning of Computex 2024. During the Tech Tour, Intel disclosed numerous facets of Lunar Lake, including their new P-Core design codenamed Lion Cove and a new wave of E-cores that are a bit more like Meteor Lake's pioneering Low Power Island E-Cores. Also disclosed was the Intel NPU 4, which Intel claims delivers up to 48 TOPS, surpassing Microsoft's Copilot+ requirements for the new age of AI PCs.

Intel's Lunar Lake represents a strategic evolution in their mobile SoC lineup, building on their Meteor Lake launch last year, focusing on enhancing power efficiency and optimizing performance across the board. Lunar Lake dynamically allocates tasks to efficient cores (E-cores) or performance cores (P-cores) based on workload demands by leveraging advanced scheduling mechanisms, which are assigned to ensure optimal power usage and performance. Still, once again, Intel Thread Director, along with Windows 11, plays a pivotal role in this process, guiding the OS scheduler to make real-time adjustments that balance efficiency with computational power depending on the intensity of the workload.
