The (Arch Linux-powered) Steam Deck was released in February of 2022 — and Phoronix reports that's helping Linux's market share on Steam. "While July was at 1.96% for Linux, the August numbers [from SteamPowered.com] show a 0.14% dip to 1.82%. Interestingly, macOS dipped by 0.27% to 1.57% while Windows rose by 0.4% to 96.61%. For those wondering why the Steam Linux numbers dropped while the Steam Deck continues to be very popular, it's possibly again another month impacted by large swings in Chinese traffic... SteamOS Holo that powers the Steam Deck gained another 2% marketshare to now commanding around 44% of the reported Linux gamers.

Among Linux gamers, AMD CPUs power around 71% of the systems. In part due to the Steam Deck being powered by an AMD APU. Meanwhile Steam on Windows has the AMD CPU marketshare at around 33%.

Samsung today revealed the world's first 32 Gb DDR5 DRAM die. From a report: The new memory die is made on the company's 12 nm-class DRAM fabrication process and not only offers increased density, but also lowers power consumption. The chip will allow Samsung to build record 1 TB RDIMMs for servers as well as lower costs of high-capacity memory modules. "With our 12nm-class 32 Gb DRAM, we have secured a solution that will enable DRAM modules of up to 1 TB, allowing us to be ideally positioned to serve the growing need for high-capacity DRAM in the era of AI (Artificial Intelligence) and big data," said SangJoon Hwang, executive vice president of DRAM product & technology at Samsung Electronics.

32 Gb memory dies not only enable Samsung to build a regular, single-rank 32 GB module for client PCs using only eight single-die memory chips, but they also allow for higher capacity DIMMs that were not previously possible. We are talking about 1 TB memory modules using 40 8-Hi 3DS memory stacks based on eight 32 Gb memory devices. Such modules may sound overkill, but for artificial intelligence (AI), Big Data, and database servers, more DRAM capacity can easily be put to good use. Eventually, 1TB RDIMMs would allow for up to 12 TB of memory in a single socket server (e.g. AMD's EPYC 9004 platform), something that cannot be done now.

An anonymous reader shares a report: AMD last week announced what are probably the last major GPU launches of this generation of graphics cards: the $449 Radeon RX 7700 XT and $499 Radeon RX 7800 XT. AMD's pricing and performance numbers pit the cards against Nvidia's GeForce RTX 4060 Ti (specifically the $499 16GB version) and the $599 RTX 4070. AMD's pricing is aggressive enough that Nvidia is quietly cutting the prices of some 16GB RTX 4060 Ti cards to $449, to match the RX 7700 XT.

The announcement about the $50 reduction was buried toward the bottom of an email that Nvidia sent to GPU reviewers ahead of AMD's launch next week; it also drew attention to Nvidia-specific features like DLSS upscaling and frame generation, which compete with AMD's GPU-agnostic FSR, plus recent DLSS improvements that improve ray-tracing performance.

ZDNet's Steven Vaughan-Nichols shares what's new in the release of Linux 6.5: The biggest news for servers -- and cloud Linux users -- is AMD Ryzen processors' P-State support. This support should mean better performance and power use across CPU cores. Intel Alder Lake CPUs have also received improved load balancing in a related development. RISC-V architecture fans will be pleased to find Linux now has Advanced Configuration and Power Interface (ACPI) support. ACPI is used in Linux and other operating systems for power management. It's vital for laptops and other battery-powered systems.

For better security, people using virtual machines or sandboxes based on Usermode Linux for testing, or running multiple versions of Linux at once, now have Landlock support. Landock is a Linux Security Module that enables applications to sandbox themselves by selecting access rights to directories. It's designed to be used by unprivileged processes while following the system security policy. To make talking with the rest of the world easier, Linux 6.5 now supports USB 4v2. This new USB-C standard will support up to an eye-watering 120Gbps. And while we're still getting used to Wi-Fi 6E, the Wi-Fi Alliance is already working on bringing us Wi-Fi 7. When Wi-Fi 7 arrives, with its theoretical maximum speed of 46Gbps, Linux will be ready. As usual, the new Linux has many more built-in audio and graphics drivers. The Bcachefs filesystem didn't make it into Linux 6.5, notes Vaughan-Nichols. "While the Bcachefs filesystem looks good, there's been a lot of developers fighting about the development process. These personal arguments have led Torvalds to decide not to incorporate Bcachefs into Linux 6.5."

Linus Torvalds announced Linux 6.5's delivery in a brief post on August 27.

The PC market is expected to return to growth in 2024, according to estimates from IDC analysts. From a report: Still, industry players might want to taper their enthusiasm. PC shipments are forecast to grow 3.7 percent year-on-year to hit 261.4 million units in 2024, putting them above 2018 levels, but not quite on par with 2019 demand. Meanwhile, 2023 is predicted to sink by 13.7 percent to 252 million units. Research manager Jitesh Ubrani called demand "tepid at best" and said 2023 will be the year with the "greatest annual decline in consumer PC shipments since the category's inception."

IDC recognizes the market still faces challenges including "concerns around the consumer market refresh cycle, businesses pushing device purchases forward, and education budgets that are not rebounding in many markets." Market hesitancy, as always, boils down to uncertainty. For one, processors are seeing what IDC called "some of the biggest shifts in commercial PC history" as AMD market share hit 11 percent in 2022 and Apple pulled in just over 5 percent that year. Apple device sales have been on a decline for multiple quarters now. Q1 2023 saw new Macs plummet more than 40 percent year-on-year, compared to an overall 25-30 percent among PC vendors. The quarter before that saw Apple shipments outperform the PC market as a whole, declining a mere 2.1 percent while other manufacturers experienced 37 percent reductions.

An anonymous reader shared this report from 9to5Linux: Just a couple of days after celebrating its 32nd anniversary , Linus Torvalds announced today the final release of the Linux 6.5 kernel series as a major update that introduces several new features, updated and new drivers for better hardware support, and other changes.

After seven weeks of RCs, Linux kernel 6.5 is here with new features like MIDI 2.0 support in ALSA, ACPI support for the RISC-V architecture, Landlock support for UML (User-Mode Linux), better support for AMD "Zen" systems, as well as user-space support for the ARMv8.8 memcpy/memset instructions. Also new in Linux 6.5 is Intel TPMI (Topology Aware Register and PM Capsule Interface) support for the power capping subsystem and a TPMI interface driver for Intel RAPL, and the "runnable boosting" feature in the EAS balancer to improve CPU utilization for specific workloads.

This release also improves SMP scheduling's load balancer to recognize SMT cores with more than one busy sibling and allows lower-priority CPUs to pull tasks to avoid superfluous migrations, and improves EXT4 file system's journalling, block allocator subsystems, and performance for parallel DIO overwrites.

AMD on Friday announced its long-awaited middle members of the Radeon RX 7000 series, the Radeon RX 7800 XT and Radeon RX 7700 XT. From a report: Today, the company is finally filling in that gap with the new Radeon RX 7800 XT and RX 7700 XT, both advertised as 1440p graphics cards and available starting at $449 and $499, respectively. Both cards will be available on September 6. And most Radeon RX 6000 and RX 7000 GPUs sold between now and September 30 will come with a free copy of Bethesda's upcoming "Skyrim in space" title, Starfield.

The RX 7700 XT and 7800 XT are based on the same RDNA 3 graphics architecture as the other 7000-series GPUs, which means a more efficient manufacturing process than the RX 6000 series, DisplayPort 2.1 support, and hardware acceleration for encoding with the AV1 video codec, which promises game streamers either higher-quality video at the same bitrate as older codecs or the same quality with a lower bitrate. AMD compared the 7800 XT and 7700 XT favorably to Nvidia's $600 upper-midrange RTX 4070 and the $500 16GB version of the RTX 4060 Ti. The new Radeon cards also support FidelityFX Super Resolution (FSR) version 3, a new version of AMD's GPU-agnostic AI upscaling technology that also promises extra AI-generated frames a la Nvidia's proprietary DLSS 3 and DLSS Frame Generation feature. But unlike Nvidia, AMD isn't restricting FSR 3 to its latest cards, and users of RX 6000-series cards plus recent Nvidia GeForce and Intel Arc cards will be able to benefit, too, at least when games start supporting it.

The UK government will spend $127m to try to win a toe-hold for the nation in the global race to produce computer chips used to power artificial intelligence. From a report: Taxpayer money will be used as part of a drive to build a national AI resource in Britain, similar to those under development in the US and elsewhere. It is understood that the funds will be used to order key components from major chipmakers Nvidia, AMD and Intel. But an official briefed on the plans told the Guardian that the $127m offered by the government is far too low relative to investment by peers in the EU, US and China. The official confirmed, in a move first reported by the Telegraph, which also revealed the investment, that the government is in advanced stages of an order of up to 5,000 graphics processing units (GPUs) from Nvidia. The company, which started out building processing capacity for computer games, has seen a sharp increase in its value as the AI race has heated up. Its chips can run language learning models such as ChatGPT.

To one-up Valve's Steam Deck, Lenovo's handheld gaming device, the "Legion Go," will have "Switch-style detachable controllers," reports Ars Technica" The Legion Go wouldn't be the very first portable PC gaming device with removable controllers; the crowd-funded OneXplayer sported a similar design last year, for instance. But few other PC-based portables have similarly mimicked the Switch Joy-cons in their ability to slide smoothly off from the main screen of the system for detached play.

Combined with a nice, wide kickstand shown in the leaked images, you should be able to give your arms a rest by setting the bulky-looking Legion Go's screen on a tabletop. The slide-off controls also mean you don't need to purchase and/or drag out a separate controller when docking the device to a TV or monitor (which we assume will be a main use case of the device's two USB-C ports). And completely detachable controls for each hand means you can keep your hands as far apart as you want while you hold each "half-controller" separately (one of our favorite unique use cases on the Switch)... The Legion Go also reportedly sports an 8-inch diagonal screen, which is 1 inch larger than Valve's and ROG's devices.

The Legion Go leaks come just months after Lenovo abandoned its button- and cooler-packed Legion line of Android-based gaming phones as part of what it said was a "gaming portfolio consolidation." The Windows 11-based Legion Go — which Windows Central says will be based on AMD's Phoenix processors — should have the high-end PC gaming support that the Legion phones lacked, as well as a more market-proven form factor.
Windows Report believes Lenovo "is preparing to launch an entire gaming ecosystem alongside the Legion Go."

"Among the accessories is a new pair of Legion AR glasses specifically tweaked for gaming." Based on the images we have, the glasses should be small enough to wear through long gaming sessions, with only one USB cable connecting them to any device (most likely for power, which means no standalone battery). The Legion AR Glasess could also feature a high refresh rate and other gaming-specific features, as the Legion branding implies they're made specifically for that...

OS News' managing editor calls Firefox "the single most important desktop Linux application," shipping in most distros (with some users later opting for a post-installation download of Chrome).

But "I'm genuinely worried about the state of browsers on Linux, and the future of Firefox on Linux in particular..." While both GNOME and KDE nominally invest in their own two browsers, GNOME Web and Falkon, their uptake is limited and releases few and far between. For instance, none of the major Linux distributions ship GNOME Web as their default browser, and it lacks many of the features users come to expect from a browser. Falkon, meanwhile, is updated only sporadically, often going years between releases. Worse yet, Falkon uses Chromium through QtWebEngine, and GNOME Web uses WebKit (which are updated separately from the browser, so browser releases are not always a solid metric!), so both are dependent on the goodwill of two of the most ruthless corporations in the world, Google and Apple respectively.

Even Firefox itself, even though it's clearly the browser of choice of distributions and Linux users alike, does not consider Linux a first-tier platform. Firefox is first and foremost a Windows browser, followed by macOS second, and Linux third. The love the Linux world has for Firefox is not reciprocated by Mozilla in the same way, and this shows in various places where issues fixed and addressed on the Windows side are ignored on the Linux side for years or longer. The best and most visible example of that is hardware video acceleration. This feature has been a default part of the Windows version since forever, but it wasn't enabled by default for Linux until Firefox 115, released only in early July 2023. Even then, the feature is only enabled by default for users of Intel graphics — AMD and Nvidia users need not apply. This lack of video acceleration was — and for AMD and Nvidia users, still is — a major contributing factor to Linux battery life on laptops taking a serious hit compared to their Windows counterparts... It's not just hardware accelerated video decoding. Gesture support has taken much longer to arrive on the Linux version than it did on the Windows version — things like using swipes to go back and forward, or pinch to zoom on images...

I don't see anyone talking about this problem, or planning for the eventual possible demise of Firefox, what that would mean for the Linux desktop, and how it can be avoided or mitigated. In an ideal world, the major stakeholders of the Linux desktop — KDE, GNOME, the various major distributions — would get together and seriously consider a plan of action. The best possible solution, in my view, would be to fork one of the major browser engines (or pick one and significantly invest in it), and modify this engine and tailor it specifically for the Linux desktop. Stop living off the scraps and leftovers thrown across the fence from Windows and macOS browser makers, and focus entirely on making a browser engine that is optimised fully for Linux, its graphics stack, and its desktops. Have the major stakeholders work together on a Linux-first — or even Linux-only — browser engine, leaving the graphical front-end to the various toolkits and desktop environments....

I think it's highly irresponsible of the various prominent players in the desktop Linux community, from GNOME to KDE, from Ubuntu to Fedora, to seemingly have absolutely zero contingency plans for when Firefox enshittifies or dies...

Why aren't more people using Linux on the desktop? Slashdot reader technology_dude shares one solution: Jack Wallen at ZDNet says establishing an "official" version of Linux may (or may not) help Linux on the desktop increase the number of users, mostly as someplace to point new users. It makes sense to me. What does Slashdot think and what would be the challenges, other than acceptance of a particular flavor?
Wallen argues this would also create a standard for hardware and software vendors to target, which "could equate to even more software and hardware being made available to Linux." (And an "official" Linux might also be more appealing to business users.) Wallen suggests it be "maintained and controlled by a collective of people from users, developers, and corporations (such as Intel and AMD) with a vested interest in the success of this project... There would also be corporate backing for things like marketing (such as TV commercials)." He also suggests basing it on Debian, and supporting both Snap and Flatpak...

In comments on the original submission, long-time Slashdot reader bobbomo points instead to kernel.org, arguing "There already is an official version of Linux called mainline. Everything else is backports." And jd (Slashdot user #1,658) believes that the official Linux is the Linux Standard Base. "All distributions, more-or-less, conform to the LSB, which gives you a pseudo 'official' Linux. About the one variable is the package manager. And there are ways to work around that."

Unfortunately, according to Wikipedia... The LSB standard stopped being updated in 2015 and current Linux distributions do not adhere to or offer it; however, the lsb_release command is sometimes still available.[citation needed] On February 7, 2023, a former maintainer of the LSB wrote, "The LSB project is essentially abandoned."
That post (on the lsb-discuss mailing list) argues the LSB approach was "partially superseded" by Snaps and Flatpaks (for application portability and stability). And of course, long-time Slashdot user menkhaura shares the obligatory XKCD comic...

It's not exactly the same thing, but days after ZDNet's article, CIQ, Oracle, and SUSE announced the Open Enterprise Linux Association, a new collaborative trade association to foster "the development of distributions compatible with Red Hat Enterprise Linux."

So where does that leave us? Share your own thoughts in the comments.

And should there be an "official" version of Linux?

An anonymous reader quotes a report from ExtremeTech: Intel has introduced a telemetry collection service by default in the latest beta driver for its Arc GPUs. You can opt out of it, but we all know most people just click "yes" to everything during a software installation. Intel's release notes for the drivers don't mention this change to how its drivers work, which is a curious omission. News of Intel adding telemetry collection to its drivers is a significant change to how its GPU drivers work. Intel has even given this new collation routine a cute name -- the Intel Computing Improvement Program. Gee, that sounds pretty wonderful. We want to improve our computing, so let's dive into the details briefly.

According to TechPowerUp, which discovered the change, Intel has created a landing page for the program that explains what is collected and what isn't. At a high level, it states, "This program uses information about your computer's performance to make product improvements that may benefit you in the future." Though that sounds innocuous, Intel provides a long list of the types of data it collects, many unrelated to your computer's performance. Those include the types of websites you visit, which Intel says are dumped into 30 categories and logged without URLs or information that identifies you, including how long and how often you visit certain types of sites. It also collects information on "how you use your computer" but offers no details. It will also identify "Other devices in your computing environment." Numerous performance-related data points are also captured, such as your CPU model, display resolution, how much memory you have, and, oddly, your laptop's average battery life. The good news is that Intel allows you to opt out of this program, which is not the case with Nvidia. According to TechPowerUp, they don't even ask for permission! As for AMD, they not only give you a choice to opt out but they also explain what data they're collecting.

As AMD continues to launch their full graphics product stacks based on their latest RDNA 3 architecture GPUs, the company is now preparing their next wave of professional cards under the Radeon Pro lineup. Following the launch of their high-end Radeon Pro W7900 and W7800 graphics cards back in the second quarter of this year, today the company is announcing the low-to-mid-range members of the Radeon Pro W7000 series: the Radeon Pro W7500 and Radeon Pro W7600. From a report: Both based on AMD's monolithic Navi 33 silicon, the latest Radeon Pro parts will hit the shelves a bit later this quarter. The two cards, as a whole, will make up what AMD defines as the mid-range segment of their professional video card market. And like their flagship counterparts, AMD is counting on a combination of RDNA 3's advanced features, including AV1 encoding support, improved compute and ray tracing throughput, and DisplayPort 2.1 outputs to help drive sales of the new video cards. That, and as is tradition, significantly undercutting NVIDIA's competing professional cards.

Not unlike their high-end counterparts, for this generation AMD has decided to expand the size of their mid-range pro graphics lineup. Whereas the previous generation had the sole W6600 (and W6400 at entry-level), the W7000 series gets both a W7600 card and a W7500 card. Besides the obvious performance difference, the other big feature separating the two cards is power consumption. The Radeon Pro W7600 is a full-height video card running at 130W, while the W7500 is explicitly designed as a sub-75W card that can be powered entirely by a PCIe slot, coming in at a cool 70 Watts. The Radeon Pro W7600 is priced at $599 -- $50 cheaper than its predecessor -- whereas the W7500 will bring up the rear of the W7000 product stack at $429.

The Steam Survey results for July 2023 were just published and it points to a large and unexpected jump in the Linux gaming marketshare. Phoronix reports; According to these new numbers from Valve, the Linux customer base is up to 1.96%, or a 0.52% jump over June! That's a huge jump with normally just moving 0.1% or so in either direction most months... It's also near an all-time high on a percentage basis going back to the early days of Steam on Linux when it had around a 2% marketshare but at that time the Steam customer size in absolute numbers was much smaller a decade ago than it is now. So if the percentage numbers are accurate, this is likely the largest in absolute terms that the Linux gaming marketshare has ever been.

When looking at the Steam Linux breakdown, the SteamOS Holo that powers the Steam Deck is now accounting for around 42% of all Linux gamers on Steam. Meanwhile, AMD CPU marketshare among Linux gamers has reached 69%. The Steam Survey results for July show Windows 10 64-bit losing 1.56% marketshare and Linux gaining the healthy 0.52% of that. This is also the first time the Linux gaming marketshare outpasses Apple macOS on Steam!

According to Windows Central, Lenovo is working on a handheld gaming PC dubbed "Legion Go," featuring Windows 11 and Ryzen chips. From the report: While details are scant right now, we understand this will sport AMD's new Phoenix processors, which the chip firm describes as ultra-thin, focused on gaming, AI, and graphics for ultrabooks. The fact the Legion Go will sport Ryzen chips pretty much guarantees that this is a Windows PC gaming handheld, as part of Lenovo's popular gaming "Legion" brand. As of writing, there's no information on exactly when this device could become available, or if, indeed, it'll become available at all.

According to our information, the Legion Go could sport an 8-inch screen, making it larger than the ASUS ROG Ally or the Steam Deck, both of which have a 7-inch display. PC and console games ported to PC are often designed for larger monitors or even TVs, and on smaller screens, UI elements can be difficult to see, especially if the game doesn't have a UI scaling option. A larger display could give the Legion Go a decent advantage over its competitors if it remains lightweight and balanced, which of course remains to be seen. The AMD Phoenix 7040 series chips are described by the firm as "ultra-thin" for powerful, but elegant ultrabook-style devices. They should lend themselves well to a device like the Legion Go, supporting 15W low-power states for lightweight games and maximized battery life, similar to the Steam Deck and ROG Ally. The Z1 Extreme in the ASUS ROG Ally can perform with a TDP below 15W, however, which could give the ROG Ally some advantages there. There's every chance the Legion Go could have other configurations we're unaware of yet, though, we'll just have to wait and see.

Monday a researcher with Google Information Security posted about a new vulnerability he independently found in AMD's Zen 2 processors. Tom's Hardware reports: The 'Zenbleed' vulnerability spans the entire Zen 2 product stack, including AMD's EPYC data center processors and the Ryzen 3000/4000/5000 CPUs, allowing the theft of protected information from the CPU, such as encryption keys and user logins. The attack does not require physical access to the computer or server and can even be executed via JavaScript on a webpage...

AMD added the AMD-SB-7008 Bulletin several hours later. AMD has patches ready for its EPYC 7002 'Rome' processors now, but it will not patch its consumer Zen 2 Ryzen 3000, 4000, and some 5000-series chips until November and December of this year... AMD hasn't given specific details of any performance impacts but did issue the following statement to Tom's Hardware: "Any performance impact will vary depending on workload and system configuration. AMD is not aware of any known exploit of the described vulnerability outside the research environment..."

AMD describes the exploit much more simply, saying, "Under specific microarchitectural circumstances, a register in "Zen 2" CPUs may not be written to 0 correctly. This may cause data from another process and/or thread to be stored in the YMM register, which may allow an attacker to potentially access sensitive information."
The article includes a list of the impacted processors with a schedule for the release of the updated firmware to OEMs.

The Google Information Security researcher who discovered the bug is sharing research on different CPU behaviors, and says the bug can be patched through software on multiple operating systems (e.g., "you can set the chicken bit DE_CFG[9]") — but this might result in a performance penalty.

Thanks to long-time Slashdot reader waspleg for sharing the news.

The June Steam Survey results show that AMD CPUs have gained significant popularity among Linux gamers, with a market share of 67% -- a remarkable 7% increase from the previous month. Phoronix reports: In part that's due to the Steam Deck being powered by an AMD SoC but it's been a trend building for some time of AMD's increasing Ryzen CPU popularity among Linux users to their open-source driver work and continuing to build more good will with the community.

In comparison, last June the AMD CPU Linux gaming marketshare came in at 45% while Intel was at 54%. Or at the start of 2023, AMD CPUs were at a 55% marketshare among Linux gamers. Or if going back six years, AMD CPU use among Linux gamers was a mere 18% during the early Ryzen days. It's also the direct opposite on the Windows side. When looking at the Steam Survey results for June limited to Windows, there Intel has a 68% marketshare to AMD at 32%.

Beyond the Steam Deck, it's looking like AMD's efforts around open-source drivers, AMD expanding their Linux client (Ryzen) development efforts over the past two years, promises around OpenSIL, and other efforts commonly covered on Phoronix are paying off for AMD in wooing over their Linux gaming customer base.

Wikipedia defines the Yocto Project as "a Linux Foundation collaborative open source project whose goal is to produce tools and processes that enable the creation of Linux distributions for embedded and IoT software that are independent of the underlying architecture of the embedded hardware."

This week the Linux Foundation shared an update on the 12-year-old Yocto Project: In an effort to support the community, The Yocto Project announced the first Long Term Support (LTS) release in October 2020. Today, we are delighted to announce that we are expanding the LTS release and extending the lifecycle from 2 to 4 years as standard.

The continued growth of the Yocto Project coincides with the welcomed addition of Exein as a Platinum Member, joining AMD/Xilinx, Arm, AWS, BMW Group, Cisco, Comcast, Intel, Meta and WindRiver. As a Member, Exein brings its embedded security expertise across billions of devices to the core of the Yocto Project...

"The Yocto Project has been at the forefront of OS technologies for over a decade," said Andrew Wafaa, Yocto Project Chairperson. "The adaptability and variety of the tooling provided are clearly making a difference to the community. We are delighted to welcome Exein as a member as their knowledge and experience in providing secure Yocto Project based builds to customers will enable us to adapt to the modern landscape being set by the US Digital Strategy and the EU Cyber Resilience Act."

"We're extremely excited to become a Platinum Partner of the Yocto Project," said Gianni Cuozzo, founder and CEO of Exein. "The Yocto Project is the most important project in the embedded Linux space, powering billions of devices every year. We take great pride in contributing our extensive knowledge and expertise in embedded security to foster a future that is both enhanced and secure for Yocto-powered devices. We are dedicated to supporting the growth of the Yocto Project as a whole, aiming to improve its support for modern languages like Rust, and assist developers and OEMs in aligning with the goals outlined in the EU Cyber Resilience Act."

An anonymous reader shared this report from Reuters: Artificial intelligence chips from Advanced Micro Devices are about 80% as fast as those from Nvidia Corp, with a future path to matching their performance, according a Friday report by an AI software firm.

Nvidia dominates the market for the powerful chips that are used to create ChatGPT and other AI services that have swept through the technology industry in recent months. The popularity of those services has pushed Nvidia's value past $1 trillion and led to a shortage of its chips that the Nvidia says it is working to resolve. But in the meantime, tech companies are looking for alternatives, with hopes that AMD will be a strong challenger. That prompted MosaicML, an AI startup acquired for $1.3 billion earlier this week, to conduct a test comparing between AI chips from AMD and Nvidia.

MosaicML evaluated the AMD MI250 and the Nvidia A100, both of which are one generation behind each company's flagship chips but are still in high demand. MosaicML found AMD's chip could get 80% of the performance of Nvidia's chip, thanks largely to a new version of AMD software released late last year and a new version of open-source software backed by Meta Platforms called PyTorch that was released in March.

VMware has joined AMD, Samsung, and members of the RISC-V community to work on an open and cross-platform framework for the development and operation of applications using confidential computing hardware. The Register reports: Revealing the effort at the Confidential Computing Summit 2023 in San Francisco, the companies say they aim to bring about an industry transition to practical confidential computing by developing the open source Certifier Framework for Confidential Computing project. Among other goals, the project aims to standardize on a set of platform-independent developer APIs that can be used to develop or adapt application code to run in a confidential computing environment, with a Certifier Service overseeing them in operation. VMware claims to have researched, developed and open sourced the Certifier Framework, but with AMD on board, plus Samsung (which develops its own smartphone chips), the group has the x86 and Arm worlds covered. Also on board is the Keystone project, which is developing an enclave framework to support confidential computing on RISC-V processors.

Confidential computing is designed to protect applications and their data from theft or tampering by protecting them inside a secure enclave, or trusted execution environment (TEE). This uses hardware-based security mechanisms to prevent access from everything outside the enclave, including the host operating system and any other application code. Such security protections are likely to be increasingly important in the context of applications running in multi-cloud environments, VMware reckons.

Another scenario for confidential computing put forward by Microsoft, which believes confidential computing will become the norm -- is multi-party computation and analytics. This sees several users each contribute their own private data to an enclave, where it can be analyzed securely to produce results much richer than each would have got purely from their own data set. This is described as an emerging class of machine learning and "data economy" workloads that are based on sensitive data and models aggregated from multiple sources, which will be enabled by confidential computing. However, VMware points out that like many useful hardware features, it will not be widely adopted until it becomes easier to develop applications in the new paradigm.
