One-Line Patch For Intel Meteor Lake Yields Up To 72% Better Performance

Michael Larabel reports via Phoronix: Covered last week on Phoronix was a new patch from Intel that with tuning to the P-State CPU frequency scaling driver was showing big wins for Intel Core Ultra "Meteor Lake" performance and power efficiency. I was curious with the Intel claims posted for a couple benchmarks and thus over the weekend set out to run many Intel Meteor Lake benchmarks on this one-line kernel patch... The results are great for boosting the Linux performance of Intel Core ultra laptops with as much as 72% better performance. [...] When looking at the CPU power consumption overall, for the wide variety of workloads tested it was just a slight uptick in power use and thus overall leading to slightly better power efficiency too. See all the data here. So this is quite a nice one-line Linux kernel patch for Meteor Lake and will hopefully be mainlined to the Linux kernel for Linux 6.11 if not squeezing it in as a "fix" for the current Linux 6.10 cycle. It's just too bad though that it took six months after launch for this tuned EPP value to be determined. Fresh benchmarks between Intel Core Ultra and AMD Ryzen on the latest Linux software will be coming up soon on Phoronix.

Intel Ditches Hyperthreading For Lunar Lake CPUs

An anonymous reader shares a report: Intel's fastest processors have included hyperthreading, a technique that lets more than one thread run on a single CPU core, for over 20 years -- and it's used by AMD (which calls it "simultaneous multi-threading") as well. But you won't see a little "HT" on the Intel sticker for any Lunar Lake laptops, because none of them use it. Hyperthreading will be disabled on all Lunar Lake CPU cores, including both performance and efficiency cores. Why? The reason is complicated, but basically it's no longer needed. The performance cores or P-Cores on the new Lunar Lake series are 14 percent faster than the same cores on the previous-gen Meteor Lake CPUs, even with the multi-thread-processing of hyperthreading disabled. Turning on the feature would come at too high a power cost, and Lunar Lake is all about boosting performance while keeping laptops in this generation thin, light, and long-lasting. That means maximizing single-thread performance -- the most relevant to users who are typically focusing on one task at a time, as is often the case for laptops -- in terms of surface area, to improve overall performance per watt. Getting rid of the physical components necessary for hyperthreading just makes sense in that context.

Intel CEO Takes Aim at Nvidia in Fight for AI Chip Dominance

Intel Chief Executive Officer Pat Gelsinger took the stage at the Computex show in Taiwan to talk about new products he expects will help turn back the tide of share losses to peers, including AI leader Nvidia. From a report: Intel showed its new Xeon 6 data center processors with more efficient cores that will allow operators to cut down the space required for a given task to a third of prior-generation hardware. Like rivals, from Advanced Micro Devices to Qualcomm, Intel touted benchmarks that showed its new silicon is significantly better than its existing options. AMD and Qualcomm's CEOs, in earlier Computex keynotes, used Intel's laptop and desktop processors to show how far ahead they are in certain aspects of technology. Gelsinger took a direct shot at Nvidia CEO Jensen Huang's claim that traditional processors like Intel's are running out of steam in the age of artificial intelligence. "Unlike what Jensen would have you believe, Moore's Law is alive and well," he said, stressing that Intel will have a major role to play in the proliferation of AI as the leading provider of PC chips. "I think of it like the internet 25 years ago, it's that big," Gelsinger said. "We see this as the fuel that's driving the semiconductor industry to reach $1 trillion by the end of the decade."

Intel Removes Knights Mill and Knights Landing Xeon Phi Support In LLVM 19

An anonymous reader shares a report: Similar to the GCC compiler dropping support for the Xeon Phi Knights Mill and Knights Landing accelerators a few days ago, Intel has also gone ahead and seen to the removal of Xeon Phi support for the LLVM/Clang 19 compiler. Since earlier this year in LLVM/Clang 18 the Xeon Phi Knights Mill and Knights Landing support was treated as deprecated. Now for the LLVM 19 release due out around September, the support is removed entirely. This aligns with GCC 14 having deprecated Xeon Phi support too and now in GCC 15 Git having the code removed.

Intel's New Thunderbolt Share Provides File and Screen Sharing Without Hurting Network Performance

Intel unveiled Thunderbolt Share on Wednesday with which it promises to streamline screen and file sharing between two PCs. Tom's Hardware: Thunderbolt Share will allow PC owners to connect their two computers with a wired connection that leverages Thunderbolt's speed (40Gbps or higher), low latency, and built-in security. It allows PC-to-PC access that shares the screen, keyboard, mouse, and storage. The software also enables folder synchronization or easy drag-and-drop file transfer between the computers. [...] Thunderbolt Share also provides uncompressed screen sharing between two PCs in the original resolution of the source computer. It also claims low latency for a smooth, responsive experience that includes the screen, keyboard, and mouse with full HD screen mirroring at up to 60 frames per second (fps). Higher resolutions could result in fewer frames per second, but Ziller said it would still be a "great experience."

Motherboard Makers Apparently To Blame For High-end Intel Core i9 CPU Failures

An anonymous reader shares a report: Earlier this month, we wrote that some of Intel's recent high-end Core i9 and Core i7 processors had been crashing and exhibiting other weird issues in some games and that Intel was investigating the cause. An Intel statement obtained by Igor's Lab suggests that Intel's investigation is wrapping up, and the company is pointing squarely in the direction of enthusiast motherboard makers that are turning up power limits and disabling safeguards to try to wring a little more performance out of the processors. "While the root cause has not yet been identified, Intel has observed the majority of reports of this issue are from users with unlocked/overclock capable motherboards," the statement reads. "Intel has observed 600/700 Series chipset boards often set BIOS defaults to disable thermal and power delivery safeguards designed to limit processor exposure to sustained periods of high voltage and frequency." These are the specific settings that Intel believes are causing problems: Disabling Current Excursion Protection (CEP) Enabling the IccMax Unlimited bit Disabling Thermal Velocity Boost (TVB) and/or Enhanced Thermal Velocity Boost (eTVB) Additional settings which may increase the risk of system instability: Disabling C-states Using Windows Ultimate Performance mode Increasing PL1 and PL2 beyond Intel recommended limits.

Intel's Stock Drops 9%. Are They Struggling to Remain Relevant?

"Intel used to dominate the U.S. chip industry," writes CNBC. But now "it's struggling to stay relevant." Intel's long-awaited turnaround looks farther away than ever after the company reported dismal first-quarter earnings. Investors pushed the shares down 9% on Friday to their lowest level of the year. Although Intel's revenue is no longer shrinking and the company remains the biggest maker of processors that power PCs and laptops, sales in the first quarter trailed estimates. Intel also gave a soft forecast for the second quarter, suggesting weak demand... Intel is the worst-performing tech stock in the S&P 500 this year, down 37%. Meanwhile, the two best-performing stocks in the index are chipmaker Nvidia and Super Micro Computer, which has been boosted by surging demand for Nvidia-based artificial intelligence servers. Intel, long the most valuable U.S. chipmaker, is now one-sixteenth the size of Nvidia by market cap. It's also smaller than Qualcomm, Broadcom, Texas Instruments, and AMD. For decades, it was the largest semiconductor company in the world by sales, but suffered seven straight quarters of revenue declines recently, and was passed by Nvidia last year. Intel's problems "are decades in the making," according to CNBC, suggesting that one turning point was Apple's decision not to use Intel's chips in its iPhone. Now nearly every smartphone built uses Arm chips built by Apple and Qualcomm, while Apple's huge orders for TSMC chips "provided the cash to annually upgrade the manufacturing equipment at TSMC, which eventually surpassed Intel." Around 2017, mobile chips from Apple and Qualcomm started adding AI parts to their chips called neural processing units, another advancement over Intel's PC processors. The first Intel-based laptop with an NPU shipped late last year. Intel has since lost share in its core PC chip business to chips that grew out of the mobile revolution... Apple stopped using Intel in its PCs in 2020. Macs now use Arm-based chips, and some of the first mainstream Windows laptops with Arm-based chips are coming out later this year. Low-cost laptops running Google ChromeOS are increasingly using Arm, too... AMD made over 20% of server CPUs sold in 2022, and shipments grew 62% that year, according to an estimate from Counterpoint Research last year. AMD surpassed Intel's market cap the same year.

TSMC Unveils 1.6nm Process Technology With Backside Power Delivery

An anonymous reader quotes a report from Tom's Hardware: TSMC announced its leading-edge 1.6nm-class process technology today, a new A16 manufacturing process that will be the company's first Angstrom-class production node and promises to outperform its predecessor, N2P, by a significant margin. The technology's most important innovation will be its backside power delivery network (BSPDN). Just like TSMC's 2nm-class nodes (N2, N2P, and N2X), the company's 1.6nm-class fabrication process will rely on gate-all-around (GAA) nanosheet transistors, but unlike the current and next-generation nodes, this one uses backside power delivery dubbed Super Power Rail. Transistor and BSPDN innovations enable tangible performance and efficiency improvements compared to TSMC's N2P: the new node promises an up to 10% higher clock rate at the same voltage and a 15%-20% lower power consumption at the same frequency and complexity. In addition, the new technology could enable 7%-10% higher transistor density, depending on the actual design. The most important innovation of TSMC's A16 process, which was unveiled at the company's North American Technology Symposium 2024, is the introduction of the Super Power Rail (SPR), a sophisticated backside power delivery network (BSPDN). This technology is tailored specifically for AI and HPC processors that tend to have both complex signal wiring and dense power delivery networks. Backside power delivery will be implemented into many upcoming process technologies as it allows for an increase in transistor density and improved power delivery, which affects performance. Meanwhile, there are several ways to implement a BSPDN. TSMC's Super Power Rail plugs the backside power delivery network to each transistor's source and drain using a special contact that also reduces resistance to get the maximum performance and power efficiency possible. From a production perspective, this is one of the most complex BSPDN implementations and is more complex than Intel's Power Via. Volume production of A16 is slated for the second half of 2026. "Therefore, actual A16-made products will likely debut in 2027," notes the report. "This timeline positions A16 to potentially compete with Intel's 14A node, which will be Intel's most advanced node at the time."

China Tells Telecom Carriers To Phase Out Foreign Chips in Blow To Intel, AMD

China's push to replace foreign technology is now focused on cutting American chip makers out of the country's telecoms systems. From a report: Officials earlier this year directed the nation's largest telecom carriers to phase out foreign processors that are core to their networks by 2027, a move that would hit American chip giants Intel and Advanced Micro Devices, people familiar with the matter said. The deadline given by China's Ministry of Industry and Information Technology aims to accelerate efforts by Beijing to halt the use of such core chips in its telecom infrastructure. The regulator ordered state-owned mobile operators to inspect their networks for the prevalence of non-Chinese semiconductors and draft timelines to replace them, the people said. In the past, efforts to get the industry to wean itself off foreign semiconductors have been hindered by the lack of good domestically made chips. Chinese telecom carriers' procurements show they are switching more to domestic alternatives, a move made possible in part because local chips' quality has improved and their performance has become more stable, the people said. Such an effort will hit Intel and AMD the hardest, they said. The two chip makers have in recent years provided the bulk of the core processors used in networking equipment in China and the world.

Intel Axes 13th Gen Core i5, i7, i9 K-series CPUs

Tom's Hardware: Intel is discontinuing its boxed overclockable Core i5, i7, and i9 Raptor Lake CPUs. Every K-series chip in the lineup will be discontinued on May 24th, 2024, after which vendors will no longer be able to purchase them. Intel's product change document states that the last product discontinuance order date and non-cancelable/non-returnable cut-off points will start on May 24th, 2024, and final shipments will end on June 28th, 2024. We don't expect 13th Gen K-series CPU supply to evaporate instantly but expect availability to gradually dissipate, along with price increases as vendors move to sell off all remaining overclockable Raptor Lake CPU inventory. That said, most 12th-Gen Alder Lake CPUs are still priced very competitively, even to this day, so we could potentially see the same behavior with these discontinued Raptor Lake CPUs (until stock inevitably runs out).

Intel Investigating Games Crashing On 13th and 14th Gen Core i9 Processors

An anonymous reader quotes a report from Ars Technica: Owners of Intel's latest 13th and 14th Gen Core i9 desktop processors have been noticing an increase in game crashes in recent months. It's happening in games like The Finals, Fortnite, and Tekken 8, and has even led Epic Games to issue a support notice to encourage Intel Core i9 13900K and 14900K owners to adjust BIOS settings. Now, Intel says it's investigating the reports. "Intel is aware of problems that occur when executing certain tasks on 13th and 14th generation core processors for desktop PCs, and is analyzing them with major affiliates," says an Intel spokesperson in a statement to ZDNet Korea. The crashes vary in severity depending on the game, with some titles producing an "out of memory" error, others simply exiting out to the desktop, and some locking up a machine entirely. Most of the games affected seem to be based on the Unreal Engine, which could point to a stability issue that Intel needs to address. The only workarounds that seem to improve stability involve manually downclocking or undervolting Intel's processors. Epic Games has suggested changing the SVID behavior to Intel Fail Safe in the BIOS settings of Asus, Gigabyte, or MSI motherboards. Custom PC builders Power GPU recommend reducing the performance core ratio limit, which seems to help with stability in certain games.
