The Rise of China GPU Makers (tomshardware.com) 78

The number of GPU startups in China is extraordinary as the country tries to gain AI prowess as well as semiconductor sovereignty, according to a new report from Jon Peddie Research. From a report: In addition, the number of GPU makers grew worldwide in recent years as demand for artificial intelligence (AI), high-performance computing (HPC), and graphics processing increased at a rather unprecedented rate. When it comes to discrete graphics for PCs, AMD and Nvidia maintain lead, whereas Intel is trying to catch up.

Tens of companies developed graphics cards and discrete graphics processors in the 1980s and the 1990s, but cut-throat competition for the highest performance in 3D games drove the vast majority of them out of business. By 2010, only AMD and Nvidia could offer competitive standalone GPUs for gaming and compute, whereas others focused either on integrated GPUs or GPU IP. The mid-2010s found the number of China-based PC GPU developers increasing rapidly, fueled by the country's push for tech self-sufficiency as well as the advent of AI and HPC as high-tech megatrends.

In total, there are 18 companies developing and producing GPUs, according to Jon Peddie Research. There are two companies that develop SoC-bound GPUs primarily with smartphones and notebooks in mind, there are six GPU IP providers, and there are 11 GPU developers focused on GPUs for PCs and datacenters, including AMD, Intel, and Nvidia, which design graphics cards that end up in our list of the best graphics cards. In fact, if we added other China-based companies like Biren Technology and Tianshu Zhixin to the list, there would be even more GPU designers. However, Biren and Tianshu Zhixin are solely focused on AI and HPC for now, so JPR does not consider them GPU developers.

AMD Improving Linux Experience When Running New GPUs Without Proper Driver Support (phoronix.com) 28

An anonymous reader shares a report: While AMD provided upstream open-source driver support for the Radeon RX 7900 series launch, the initial user experience can be less than desirable if running a new Radeon GPU but initially running an out-of-date kernel or lacking the necessary firmware support. With a new patch series posted AMD is looking to improve the experience by being able to more easily fallback to the firmware frame-buffer when their AMDGPU kernel graphics driver fails to properly load.

With the new IP-based discovery "block by block" approach to how the open-source AMD Radeon Linux graphics driver is managing the hardware initialization with RDNA3 and moving forward, the AMDGPU driver will try to probe all Radeon GPUs even if it might not end up being fully supported. In turn that ends up destroying the system firmware frame-buffer. But right now in the case of booting an RDNA3 GPU with a slightly out of date kernel (pre-6.0) or lacking the necessary RDNA3 firmware for hardware initialization, it can mean the screen freezing or system appearing unresponsive.

Tesla Launches Steam In Its Cars With Thousands of Games (electrek.co) 105

Tesla has launched Steam integration inside its Model S and Model X electric cars with thousands of games now playable. Electrek reports: Today, Tesla launched Steam Beta for Model S and Model X as part of its "holiday update." We reported all the details of Tesla's holiday update earlier today for most Tesla vehicles, but the Steam integration is only for the refreshed Model S and Model X produced over the last two years. That's because Tesla's two flagship vehicles are equipped with a more powerful entertainment computer designed for video games.

With the unveiling of the new Model S and Model X, Tesla announced the new gaming computer: "Up to 10 teraflops of processing power enables in-car gaming on-par with today's newest consoles via Tesla Arcade. Wireless controller compatibility allows gaming from any seat." A known chip leaker, Patrick Schur, posted a diagram of Tesla's new gaming computer powered by the AMD Navi 23 GPU. The system is integrated and connects directly to two touchscreens inside the Model S and Model X to play games, watch entertainment, and perform other functions. Musk also revealed that the new computer has more storage space to be able to handle more games on the platform at the same time, which is going to be useful to handle your Steam library.
The holiday update also brings support for Apple Music, an update to Dog Mode, improvements to Tesla's "Light Show" feature, and a bunch of smaller features/updates.

Linux 6.1 Released With Initial Support for Rust-Based Kernel Development (lwn.net) 65

"Linus has released the 6.1 kernel," reports LWN.net — and it's the one with initial support for kernel development in Rust.

Elsewhere LWN explains the specifics of this milestone: No system with a production 6.1 kernel will be running any Rust code, but this change does give kernel developers a chance to play with the language in the kernel context and get a sense for how Rust development feels....

There are other initiatives underway, including the writing of an Apple graphics driver in the Rust language. For the initial merge into the mainline kernel, though, Linus Torvalds made it clear that as little functionality as possible should be included. So those drivers and their support code were trimmed out and must wait for a future kernel release. What is there is the support needed to build a module that can be loaded into the kernel, along with a small sample module.... Torvalds asked for something that could do "hello world" and that is what we got. It is something that can be played with, but it cannot be used for any sort of real kernel programming at this point.

That situation will, hopefully, change in the near future.

Meanwhile, Linux 6.1 also includes "support for destructive BPF programs, some significant io_uring performance improvements, better user-space control over transparent huge-page creation, improved memory-tiering support."

The Register adds: Other interesting additions include more support for the made-in-China LoongArch CPU architecture, introductory work to support Wi-Fi 7 and security fixes for some flaky Wi-Fi routines in previous versions of the kernel. There's also plenty of effort to improve the performance of Linux on laptops, and enhanced power efficiency for AMD's PC-centric RYZEN silicon.

AMD Says Transistor Tech Will Keep Moore's Law Alive For 6 To 8 Years (theregister.com) 40

Chipmaker AMD has hinted that new transistor technology will keep Moore's Law alive for the next six to eight years, but as one might guess, it will cost more. From a report: Meanwhile, the company still plans to market new chips based on its Zen 4 architecture next year, including Bergamo, which is intended to compete against Arm-based chips for cloud-native computing. In an interview with Wells Fargo analyst Aaron Rakers at the financial outfit's TMT Summit, AMD CTO Mark Papermaster talked about future directions and the company's near-term roadmap. Rakers asked about the Zen family and its chiplet-based architecture versus the monolithic architecture seen with Intel's CPUs, and whether this would continue to serve AMD for the next four to five years, or whether another novel approach might be needed.

"Innovation always finds its way around barriers," Papermaster said. "I can see exciting new transistor technology for the next -- as far as you can really plot these things out -- about six to eight years, and it's very, very clear to me the advances that we're going to make to keep improving the transistor technology, but they're more expensive," he said. In the past, chipmakers like AMD and Intel could double the transistor density every 18 to 24 months and stay within the same cost envelope, but that is not the case anymore, Papermaster claimed. "So, we're going to have innovations in transistor technology. We're going to have more density. We're going to have lower power, but it's going to cost more. So how you put solutions together has to change," he said.

PCI Standards Group Deflects, Assigns Blame for Melting GPU Power Connectors (arstechnica.com) 130

An anonymous reader shares a report: Nvidia's new RTX 4090 and 4080 GPUs both use a new connector called 12VHPWR to deliver power as a way to satisfy ever-more power-hungry graphics cards without needing to set aside the physical space required for three or four 8-pin power connectors. But that power connector and its specifications weren't created by Nvidia alone -- to ensure interoperability, the spec was developed jointly by the PCI Express Special Interest Group (PCI-SIG), a body that includes Nvidia, AMD, Intel, Arm, IBM, Qualcomm, and others.

But the overheating and melting issues experienced by some RTX 4090 owners recently have apparently prompted the PCI-SIG to clarify exactly which parts of the spec it is and is not responsible for. In a statement reported by Tom's Hardware, the group sent its members a reminder that they, not the PCI-SIG, were responsible for safety testing products using connector specs like 12VHPWR. "Members are reminded that PCI-SIG specifications provide necessary technical information for interoperability and do not attempt to address proper design, manufacturing methods, materials, safety testing, safety tolerances, or workmanship," the statement reads. "When implementing a PCI-SIG specification, Members are responsible for the design, manufacturing, and testing, including safety testing, of their products."

Head of Intel Foundry Services Resigns Just As Chip Biz Gets Going (theregister.com) 26

The head of Intel's revitalized contract chip manufacturing business plans to step down, The Register has learned, creating a setback for the x86 behemoth's big bet to take on Asian foundry giants TSMC and Samsung as part of its comeback plan. From the report: Randhir Thakur, senior vice president and president of Intel Foundry Services, "has decided to pursue other opportunities" but will continue to lead the business unit through the first quarter of 2023 to "ensure a smooth transition to a new leader," Intel CEO Pat Gelsinger said in an email to employees Monday that was seen by el Reg. Intel spokesperson William Moss confirmed the news with us. "We're grateful to Randhir for the tremendous progress IFS has made and for laying the foundation for Intel to become a world-class systems foundry," Moss said in a statement. "We wish him all the best in his new endeavors."

In his email, Gelsinger said he will share more information soon "about the new leader" for Intel Foundry Services, suggesting the company may have a successor in place -- or is at least close to having one. "Randhir has been a key member of the Executive Leadership Team for the past two and a half years and has served in several senior leadership roles since he joined us in 2017," Gelsinger wrote. "... His contributions to our [Integrated Device Manufacturing] 2.0 transformation are many, but most notable is his leadership in standing up our IFS business."

Intel revitalized its contract chip manufacturing business in early 2021 and renamed it Intel Foundry Services with the goal of competing with TSMC and Samsung, the world's two largest contract chip manufacturers that make chips for the likes of Intel rivals, including AMD, Nvidia, and Apple. In his email to employees, Gelsinger credited Thakur for establishing a "seasoned leadership team with veterans from leading foundries" like TSMC and Samsung. He added that the Intel Foundry Services leader also "secured major customer wins in the mobile and auto segments" and helped the company win the US government's RAMP-C award along with four customers for chip designs on its 18A node. "Since Q2, IFS has expanded engagements to seven of the 10 largest foundry customers coupled with consistent pipeline growth to include 35 customer test chips," Gelsinger said. "This is tremendous progress in only 20 months!"
Intel has a pending $5.4 billion acquisition of Israeli chip manufacturer Tower Semiconductor, notes The Register. "Analysts responding to the news of Thakur's resignation said the move is likely happening because Intel plans to put Tower Semiconductor's management in charge of Intel Foundry Services." The deal is expected to close in the first quarter of 2023.

AMD Finally Opens Up Its Radeon Raytracing Analyzer 'RRA' Source Code (phoronix.com) 4

Michael Larabel, reporting for Phoronix: This summer AMD announced the Radeon Raytracing Analyzer "RRA" as part of their developer software suite for helping to profile ray-tracing performance/issues on Windows and Linux with both Direct3D 12 and the Vulkan API. Initially the RRA 1.0 release was binary-only but now AMD has made good on their "GPUOpen" approach and made it open-source.

As noted back in my original article from July on the Radeon Raytracing Analyzer release: "Radeon Raytracing Analyzer is hosted on GitHub but the only content in the actual Git repository right now is documentation, so it would appear that at least initially this is a closed-source package though some documentation also says it's MIT licensed."

Last week that was cleared up with the Radeon Raytracing Analyzer source code going public. There are build instructions for compiling the RRA 1.0 sources on both Microsoft Windows and Linux while the Linux instructions are tailoring to Ubuntu use. Building the Radeon Raytracing Analyzer depends upon the Qt 5.15 toolkit.

Intel Takes on AMD and Nvidia With Mad 'Max' Chips For HPC (theregister.com) 26

Intel's latest plan to ward off rivals from high-performance computing workloads involves a CPU with large stacks of high-bandwidth memory and new kinds of accelerators, plus its long-awaited datacenter GPU that will go head-to-head against Nvidia's most powerful chips. From a report: After multiple delays, the x86 giant on Wednesday formally introduced the new Xeon CPU family formerly known as Sapphire Rapids HBM and its new datacenter GPU better known as Ponte Vecchio. Now you will know them as the Intel Xeon CPU Max Series and the Intel Data Center GPU Max Series, respectively, which were among the bevy of details shared by Intel today, including performance comparisons. These chips, set to arrive in early 2023 alongside the vanilla 4th generation Xeon Scalable CPUs, have been a source of curiosity within the HPC community for years because they will power the US Department of Energy's long-delayed Aurora supercomputer, which is expected to become the country's second exascale supercomputer and, consequently, one of the world's fastest.

In a briefing with journalists, Jeff McVeigh, the head of Intel's Super Compute Group, said the Max name represents the company's desire to maximize the bandwidth, compute and other capabilities for a wide range of HPC applications, whose primary users include governments, research labs, and corporations. McVeigh did admit that Intel has fumbled in how long it took the company to commercialize these chips, but he tried to spin the blunders into a higher purpose. "We're always going to be pushing the envelope. Sometimes that causes us to maybe not achieve it, but we're doing that in service of helping our developers, helping the ecosystem to help solve [the world's] biggest challenges," he said. [...] The Xeon Max Series will pack up to 56 performance cores, which are based on the same Golden Cove microarchitecture features as Intel's 12th-Gen Core CPUs, which debuted last year. Like the vanilla Sapphire Rapids chips coming next year, these chips will support DDR5, PCIe 5.0 and Compute Express Link (CXL) 1.1, which will enable memory to be directly attached to the CPU over PCIe 5.0.

Chinese Chip Designers Slow Down Processors To Dodge US Sanctions (arstechnica.com) 55

Cutting-edge semiconductor companies tweak specs to comply with export controls. From a report: Alibaba and start-up Biren Technology are tweaking their most advanced chip designs to reduce processing speeds and avoid US-imposed sanctions aimed at suppressing Chinese computing power. Alibaba, Biren, and other Chinese design houses have spent years and millions of dollars creating the blueprints for advanced processors to power the country's next generation of supercomputers, artificial intelligence algorithms and data centers. These are produced offshore by the world's biggest contract chipmaker, Taiwan Semiconductor Manufacturing. But sanctions announced by Washington last month that cap the processing power of any semiconductor shipped into China without a license have thrown a wrench into their ambitions.

Both Alibaba and Biren had already conducted expensive test runs of their latest chips at TSMC when Washington unveiled the controls. The rules have forced the companies to halt further production and make changes to their designs, according to six people briefed on the situation. They mark another blow for Alibaba, the tech group founded by billionaire Jack Ma. Its shares have lost 80 percent of their value since Beijing canceled sister group Ant's initial public offering two years ago. The group's new chip was to be its first graphics processing unit and was close to being unveiled, according to three people close to the matter. The US export controls extend to third-country chip manufacturers because almost all semiconductor fabrication plants use American components or software, meaning the rules may amount to an embargo on all high-end processors entering China. Washington earlier restricted such imports from California chip companies Nvidia and AMD.

AMD Unveils RDNA 3-Based Radeon RX 7900 XTX and 7900 XT Graphics Cards (hothardware.com) 50

Slashdot readers MojoKid and williamyf share the news of AMD's two new high-end graphics cards, the Radeon RX 7900 XTX and 7900 XT. "Priced at $999 and $899 respectively and available in December this year, the new Radeon cards are expected to go toe-to-toe with NVIDIA's GeForce RTX 4080 and 4090," writes MojoKid. HotHardware reports: AMD states that its goals for RDNA 3 are to accelerate performance-per-watt leadership and to raise the bar for high resolution and high framerate gaming. AMD has turned to a chiplet architecture to accomplish these goals, a first for gaming GPUs. The chiplet complexes consist of a 5nm graphics compute die (GCD), which is flanked top and bottom by up to six 6nm memory and cache dice (MCD). The RX 7900 XTX uses the full complement of 6 MCDs which aggregates as a 384-bit memory bus (64-bit per die) with GDDR6 memory offering 20Gbps of throughput. The RX 7900 XT uses 5 MCDs with a corresponding 320-bit bus.

All of this increased bandwidth and resources translates to what AMD claims is up to a 1.7X uplift in performance for the Radeon RX 7900 XTX versus its previous gen Radeon RX 6950 XT card in high resolution gaming. This could put the card within striking distance of NVIDIA's GeForce RTX 4090 possibly, but it's hard to say until cards ship to independent reviewers for testing. Regardless, gamers will appreciate the RX 7900 XTX's price point versus NVIDIA's $1600 top-end beast.

Steam on Chromebooks Enters Beta, Adds AMD Support (arstechnica.com) 11

It has been almost three years since Chromebook users got word that Steam support is coming to ChromeOS. We're still not totally there yet, but today Google announced that it's ready to enter beta testing. From a report: In a blog post, Zach Alcorn, Google product manager, announced that Steam on Chromebooks is available as a beta with ChromeOS 108.0.5359.24 and later. Steam on ChromeOS entered alpha in March, and Alcorn said the updates announced today are based on "thousands of gameplay reports." The Steam on ChromeOS alpha required not just an Intel CPU, but also an Intel 11th-gen Core i5 chip with Intel's Iris Xe graphics. The beta supports Intel's latest 12th-gen chips and extends support to Team Red. Alcorn said the beta supports AMD's Ryzen 5000 C-Series CPUs.

Arm Disputes Qualcomm's Claim It's Licensing Only to OEMs (Not Chipmakers) After 2024 (fierceelectronics.com) 45

Fierce Electronics reports on "a complex legal battle in U.S. district court" between Qualcomm and Arm "over licensing of intellectual property with potentially far-reaching impact..." Normally, Arm licenses its architectural designs and related IP to chipmakers such as Nvidia or Qualcomm, which in turn produce chips that are then sold to OEMs that use those chips to make servers and other computers and devices. In an updated Qualcomm counterclaim made public Oct. 26, Qualcomm argues that Arm is no longer going to license its CPU designs after 2024 to Qualcomm and other chip companies under technology license agreements. Instead, Qualcomm asserts, Arm will only license to a broad array of device makers....

Arm has not yet formally responded to Qualcomm's latest counterclaim but told Fierce Electronics via email on Friday that Qualcomm's complaint is "riddled with inaccuracies" that Arm will address in a formal legal response in coming weeks....

[Analyst] Dylan Patel in SemiAnalysis also said the counterclaim shows Arm is not planning to allow external GPUs, NPUs or ISPs in Arm-based SoCs. "It seems that Arm is effectively bundling its other IP with the CPU IP in a take-it-or-leave-it model," Patel said. "That would mean Samsung's licensing deal with AMD for GPU or Mediatek with Imagination GPU is not longer allowed after 2024...." Qualcomm argues Arm is making it clear to the marketplace that "it will act recklessly and opportunistically, threatening the development of new and innovative products as a negotiating tactic, not because it has valid license and trademark claims."

Again, Arm has called Qualcomm's complaint "riddled with inaccuracies." Jack Gold, an analyst at J. Gold Associates, tells Fierce Wireless that If Qualcomm's counterclaim is accurate, "this is a troubling step for the industry." If Arm were to get rid of tech licensing as described by Qualcomm, it would give rise to RISC-V use, something Arm "should be worried about," Gold said....

[Analyst] Patel has also questioned if Arm's original lawsuit is more than just about money and might be because Softbank (owner of Arm) and Arm remain angry that Qualcomm, as Patel puts it, worked with regulators to block Nvidia's $40 billion acquisition of Arm. After working for more than a year to seal the deal, Nvidia and SoftBank announced the termination of the proposed deal on Feb. 7, 2022, due to "significant regulatory challenges." Arm was expected to go public within a year, but an IPO has not occurred as of late October.

TSMC Wants To Unleash a Flood of Chiplet Designs With 3DFabric Alliance (theregister.com) 8

An anonymous reader quotes a report from The Register: AMD turned to advanced packaging to create chiplet designs and become a formidable CPU player again. Apple used the tech to beef up the power of its M1 Ultra chip. And Intel is pinning its future success on 2D and 3D multi-die packaging technologies as part of its ambitious comeback plan. Now TSMC, the world's largest contract chipmaker, wants to make chiplet-based products easier and faster to manufacture using its growing toolbox of advanced packaging tech that has already benefited the likes of AMD, Apple, and others. The Taiwanese foundry giant plans to do this through the formation of the 3DFabric Alliance, announced Thursday, which aims to help chip designers implement advanced packaging tech into their plans faster by collaborating with partner companies that are key to the development process.

TSMC's partners cover several important elements of chip development, from electronic design automation and memory to substrates and testing. As part of the new alliance, they will have early access to TSMC's 3DFabric portfolio of 3D silicon stacking and advanced packaging technologies. The goal is to allow these partners to build new solutions in parallel with the development of TSMC's 3DFabric tech so that chip designers can get their hands on the tools, technologies, materials, and other resources necessary to make multi-die chip packages faster. TSMC's 3DFabric portfolio includes brand-new technology, like system-on-integrated-chips (SoIC), which underpins the 3D V-Cache tech in AMD's Milan-X and Ryzen 7 5800X3D processors that came out this year. The portfolio also includes older technologies: integrated-fan-out and chip-on-wafer-on-substrate (CoWoS), which have received new iterations over the past several years. Those using CoWoS include Nvidia and Amazon Web Services. Representatives from AMD, Nvidia, and AWS gave support for the new alliance, which is one of several set up by TSMC as part of its Open Innovation Platform initiative.
TSMC veep of R&D, LC Lu, said while advanced packaging technologies can "open the door to a new era of chip-level and system-level innovation," "extensive ecosystem collaboration" is required to "help designers navigate the best path through the myriad options and approaches available to them."

"Through the collective leadership of TSMC and our ecosystem partners, our 3DFabric Alliance offers customers an easy and flexible way to unlocking the power of 3D [integrated circuits] in their designs," he added.

Memtest86+ Is Back After 9 Years (tomshardware.com) 60

Memtest86+ just got its first update after 9 years. The program has reportedly been rewritten from scratch and is back in active development. The new version, 6.0, features a plethora of updates to bring the application up to date, and support the latest system hardware from Intel and AMD. Tom's Hardware reports: For the uninitiated, MemTest86 was originally created back in the mid 1990s, and was one of the earliest DDR memory testing applications for personal computers. But development stopped in 2013 once Memtest86 was split into Memtest86 and Memtest86", with the former being bought by PassMark. Officially, we don't know why development stopped. But compared to the now modern Memtest86, Memtest86+ is the open-source variant.

Needless to say, version 6.00 features a lot of updates, which were required to bring it up to modern standards compared to the 2013 version. The new version includes completely rewritten code for UEFI-based motherboards, the modern version of a BIOS, for both 32-bit and 64-bit versions of the application. Furthermore, the application features added support for x64 long mode paging, support for up to 256 cores, added detection for DDR4 and DDR5 memory -- since DDR3 was the latest memory standard in 2013 -- and adds support for XMP version 3.0.

CPU support has been significantly enhanced, addingdetection for all pre-Zen and AMD Zen-based processors ranging from the Ryzen 1000 series to 7000 series, and any older parts that were made after 2013. Intel support has also been added for chips up to 13th gen Raptor Lake. Finally, the last patch notes indicate version 6.0 adds support for older Nvidia and AMD chipsets - probably pre-2010 since it mentions Nvidia nForce chipsets, along with numerous bug fixes, optimizations and enhancements.

Overclocker Breaks CPU Frequency World Record with Intel's Raptor Lake Core i9-13900K (tomshardware.com) 50

Hardcore overclocker Elmor "officially broke the CPU frequency world record with Intel's brand-new Core i9-13900K 24-core processor," reports Tom's Hardware — by hitting "a staggering 8.812GHz using liquid nitrogen cooling, dethroning the 8-year reigning champion, the FX-8370, by 90MHz." That's right; it took eight years for a new CPU architecture to dethrone AMD's FX series processors. Those chips are infamous for their mediocre CPU performance at launch; however, these chips scaled incredibly well under liquid nitrogen overclocking....

Elmor accomplished this monumental feat thanks to Intel's new highly-clocked 13th Gen Raptor Lake CPU architecture. Out of the box, the Core i9-13900K can run over 5.5GHz on all P-cores while also hitting 5.8GHz under lightly threaded workloads. The 13900K is, by far, Intel's highest-clocking chip to date.

VirtualBox 7.0 Adds First ARM Mac Client, Full Encryption, Windows 11 TPM (arstechnica.com) 19

Nearly four years after its last major release, VirtualBox 7.0 arrives with a... host of new features. Chief among them are Windows 11 support via TPM, EFI Secure Boot support, full encryption for virtual machines, and a few Linux niceties. From a report: The big news is support for Secure Boot and TPM 1.2 and 2.0, which makes it easier to install Windows 11 without registry hacks (the kind Oracle recommended for 6.1 users). It's strange to think about people unable to satisfy Windows 11's security requirements on their physical hardware, but doing so with a couple clicks in VirtualBox, but here we are. VirtualBox 7.0 also allows virtual machines to run with full encryption, not just inside the guest OSâ"but logs, saved states, and other files connected to the VM. At the moment, this support only works through the command line, "for now," Oracle notes in the changelog.

This is the first official VirtualBox release with a Developer Preview for ARM-based Macs. Having loaded it on an M2 MacBook Air, I can report that the VirtualBox client informs you, extensively and consistently, about the non-production nature of your client. The changelog notes that it's an "unsupported work in progress" that is "known to have very modest performance." A "Beta Warning" shows up in the (new and unified) message center, and in the upper-right corner, a "BETA" warning on the window frame is stacked on top of a construction-style "Dev Preview" warning sign. It's still true that ARM-based Macs don't allow for running operating systems written for Intel or AMD-based processors inside virtual machines. You will, however, be able to run ARM-based Linux installations in macOS Venture that can themselves run x86 processors using Rosetta, Apple's own translation layer.

China May Prove Arm Wrong About RISC-V's Role In the Datacenter (theregister.com) 49

Arm might not think RISC-V is a threat to its newfound foothold in the datacenter, but growing pressure on Chinese chipmaking could ultimately change that, Forrester Research analyst Glenn O'Donnell tells The Register. From the report: Over the past few years the US has piled on export bans and trade restrictions on Chinese chipmakers in an effort to stall the country's semiconductor industry. This has included barring companies with ties to the Chinese military from purchasing x86 processors and AI kit from the likes of Intel, AMD, and Nvidia. "Because the US-China trade war restricts x86 sales to China, Chinese infrastructure vendors and cloud providers need to adapt to remain in business," O'Donnell said. "They initially pivoted to Arm, but trade restrictions exist there too. Chinese players are showing great interest in RISC-V."

RISC-V provides China with a shortcut around the laborious prospect of developing their own architecture. "Coming up with a whole new architecture is nearly impossible," O'Donnell said. But "a design based on some architecture is very different from the architecture itself." So it should come as no surprise that the majority of RISC-V members are based in China, according to a report published last year. And the country's government-backed Chinese Academy of Sciences is actively developing open source RISC-V performance processors.

Alibaba's T-Head, which is already deploying Arm server processors and smartNICs, is also exploring RISC-V-based platforms. But for now, they're largely limited to edge and IoT appliances. However, O'Donnell emphasizes that there is no technical reason that would prevent someone from developing a server-grade RISC-V chip. "Similar to Arm, many people dismiss RISC-V as underpowered for more demanding applications. They are wrong. Both are architectures, not specific designs. As such, one can design a powerful processor based on either architecture," he said. [...] One of the most attractive things about RISC-V over Softbank-owned Arm is the relatively low cost of building chips based on the tech, especially for highly commoditized use cases like embedded processors, O'Donnell explained. While nowhere as glamorous as something like a server CPU, embedded applications are one of RISC-V's first avenues into the datacenter. [...] These embedded applications are where O'Donnell expects RISC-V will see widespread adoption, including in the datacenter. Whether the open source ISA will rise to the level of Arm or x86 is another matter entirely.

The Biden Administration Issues Sweeping New Rules on Chip-Tech Exports To China (protocol.com) 90

The U.S. unveiled a set of new regulations Friday that aim to choke off China's access to advanced chips, the tools necessary to manufacture years-old designs, and the service and support mechanisms needed to keep chip fabrication systems running smoothly. From a report: On a briefing call with reporters Thursday, administration officials said the goal is to block the People's Liberation Army and China's domestic surveillance apparatus from gaining access to advanced computing capabilities that require the use of advanced semiconductors. The chips, tools, and software are helping China's military, including aiding the development of weapons of mass destruction, according to the officials, who asked to remain anonymous to discuss the administration's policies freely.

The new rules are comprehensive, and cover a range of advanced semiconductor technology, from chips produced by the likes of AMD and Nvidia to the expensive, complex equipment needed to make those chips. Much of highest-quality chip manufacturing equipment is made by three U.S. companies: KLA, Applied Materials, and Lam Research, and cutting off China's access to their tools has the potential to damage the country's ambitions to become a chipmaking powerhouse. The Biden administration's new controls on chip exports represent a significant shift in U.S. policy related to China. For decades, the U.S. has attempted to keep China two generations of tech behind, typically by denying China access to the tools necessary to make advanced chips, or other technology, themselves. Now, the goal looks to be to cripple China's ability to produce chips with technology that is nearly a decade old, several generations behind the state-of-the-art capabilities.

Intel CTO Wants Developers To Build Once, Run On Any GPU (venturebeat.com) 58

Greg Lavender, CTO of Intel, spoke to VentureBeat about the company's efforts to help developers build applications that can run on any operating system. From the report: "Today in the accelerated computing and GPU world, you can use CUDA and then you can only run on an Nvidia GPU, or you can go use AMD's CUDA equivalent running on an AMD GPU,â Lavender told VentureBeat. "You can't use CUDA to program an Intel GPU, so what do you use?" That's where Intel is contributing heavily to the open-source SYCL specification (SYCL is pronounced like "sickle") that aims to do for GPU and accelerated computing what Java did decades ago for application development. Intel's investment in SYCL is not entirely selfless and isn't just about supporting an open-source effort; it's also about helping to steer more development toward its recently released consumer and data center GPUs. SYCL is an approach for data parallel programming in the C++ language and, according to Lavender, it looks a lot like CUDA.

To date, SYCL development has been managed by the Khronos Group, which is a multi-stakeholder organization that is helping to build out standards for parallel computing, virtual reality and 3D graphics. On June 1, Intel acquired Scottish development firm Codeplay Software, which is one of the leading contributors to the SYCL specification. "We should have an open programming language with extensions to C++ that are being standardized, that can run on Intel, AMD and Nvidia GPUs without changing your code," Lavender said. Lavender is also a realist and he knows that there is a lot of code already written specifically for CUDA. That's why Intel developers built an open-source tool called SYCLomatic, which aims to migrate CUDA code into SYCL. Lavender claimed that SYCLomatic today has coverage for approximately 95% of all the functionality that is present in CUDA. He noted that the 5% SYCLomatic doesn't cover are capabilities that are specific to Nvidia hardware.

With SYCL, Lavender said that there are code libraries that developers can use that are device independent. The way that works is code is written by a developer once, and then SYCL can compile the code to work with whatever architecture is needed, be it for an Nvidia, AMD or Intel GPU. Looking forward, Lavender said that he's hopeful that SYCL can become a Linux Foundation project, to further enable participation and growth of the open-source effort. [...] "We should have write once, run everywhere for accelerated computing, and then let the market decide which GPU they want to use, and level the playing field," Lavender said.
