An anonymous reader quotes a report from ZDNet: RIP, 486 processor. You've had a long run since Intel released you back in 1989. While Microsoft stopped supporting you with the release of Windows XP in 2001, Linux kept you alive and well for another 20+ years. But all good things must come to an end, and with the forthcoming release of the Linux 6.15 kernel, the 486 and the first Pentium processors will be sunsetted.

Why? Linus Torvalds wrote recently on the Linux Kernel Mailing List (LKML), "I really get the feeling that it's time to leave i486 support behind. There's zero real reason for anybody to waste one second of development effort on this kind of issue." Senior Linux kernel developer Ingo Molnar put Torvalds' remark into context, writing, "In the x86 architecture, we have various complicated hardware emulation facilities on x86-32 to support ancient 32-bit CPUs that very very few people are using with modern kernels. This compatibility glue is sometimes even causing problems that people spend time to resolve, which time could be spent on other things." "This will be the first time Linux has dropped support for a major chip family since 2012, when Linux stopped supporting the 386 family," notes ZDNet's Steven Vaughan-Nichols. "Moving forward, the minimum supported x86 CPU will now be the original Pentium (P5) or newer, requiring the presence of the Time Stamp Counter (TSC) and the CMPXCHG8B (CX8) instruction. These features are absent in the older 486 and early 586 processors, such as the IDT WinChip and AMD Elan families."

That said, you can continue running Linux on Pentium CPUs, but you'll have to "run museum kernels," as Torvalds pointed out in 2022 when he first floated the idea of ending support for 486.

According to Bloomberg, the Trump administration plans to revise a set of chip trade restrictions called the "AI diffusion" rule, which were scheduled to take effect on May 15. CNBC reports: The rule, which was proposed in the last days of the Biden administration, organizes countries into three different tiers, all of which have different restrictions on whether advanced AI chips like those made by Nvidia, AMD, and Intel can be shipped to the country without a license.

Chipmakers including Nvidia and AMD have been against the rule. AMD CEO Lisa Su told CNBC on Wednesday that the U.S. should strike a balance between restricting access to chips for national security and providing access, which will boost the American chip industry. Nvidia CEO Jensen Huang said earlier this week that being locked out of the Chinese AI market would be a "tremendous loss."

Microsoft has unveiled a substantial AI-focused update for Windows 11 and Copilot+ PCs, introducing features that leverage neural processing units across the operating system. The update centers on AI-powered helpers across core Windows apps, with an intelligent agent in Settings that can locate and adjust options via natural voice commands. Key additions include expanded Click To Do functionality, allowing users to draft Word content based on screen context, engage Reading Coach, or send details directly to Excel tables.

The Photos app gains a relight feature with support for three customizable light sources, while Paint adds object selection and text-to-sticker generation. Snipping Tool will automatically detect and crop prominent screen content, adding text extraction and color picking capabilities. System-level enhancements include an updated Start menu with phone companion integration, AI-powered actions in File Explorer for content summarization, and text generation in Notepad with new formatting options.

Most features will debut first on Windows Insider builds for Snapdragon-powered Copilot+ PCs before expanding to systems with AMD or Intel chips. Several tools, including Ask Copilot and Reading Coach, are already available to Insiders.

"It is the fastest, most efficient transistor ever," proclaims an announcment from Peking University. "And most important of all, there's no trace of silicon involved," adds ZME Science. From the South China Morning Post: A team of researchers at Peking University claims to have shattered chip performance limits and proven that China can use new materials to "change lanes" in the semiconductor race by circumventing silicon-based roadblocks entirely.

The researchers, led by physical chemistry professor Peng Hailin, said their self-engineered 2D transistor could operate 40 per cent faster than Intel and TSMC's cutting-edge 3-nanometre silicon chips, while consuming 10 per cent less energy.... "While this path is born out of necessity due to current sanctions, it also forces researchers to find solutions from fresh perspectives," [Hailin] added.
"Peking's major innovation comes from the two-dimensional nature of their transistors, facilitated by using an element other than silicon," writes Tom's Hardware: BiâOâSe, or bismuth oxyselenide, is a semiconductor material studied for its use in sub-1nm process nodes for years, largely thanks to its ability to be a 2D semiconductor. Two-dimensional semiconductors, like 2D BiâOâSe, are more flexible and sturdy at a small scale than silicon, which runs into reduced carrier mobility at even the 10nm node. Such breakthroughs into stacked 2D transistors and the move from silicon to bismuth are exciting for the future of semiconductors and are necessary for the Chinese industry to compete on the leading edge of semiconductors.
ZME Science adds this note of skepticism. "Turning laboratory breakthroughs into commercial chips typically takes years — sometimes decades..."

Ars Technica's Andrew Cunningham reports: Intel's oddball Core Ultra 200V laptop chips -- codenamed Lunar Lake -- will apparently be a one-off experiment, not to be replicated in future Intel laptop chips. They're Intel's only processors with memory integrated onto the CPU package; the only ones with a neural processing unit that meets Microsoft's Copilot+ performance requirements; and the only ones with Intel's best-performing integrated GPUs, the Intel Arc 130V and 140V.

Today, Intel announced some updates to its graphics driver that specifically benefit those integrated GPUs, welcome news for anyone who bought one and is trying to get by with it as an entry-level gaming system. Intel says that version 32.0.101.6734 of its graphics driver can speed up average frame rates in some games by around 10 percent, and can speed up "1 percent low FPS" (that is, for any given frames per second measurement, whatever your frame rate is the slowest 1 percent of the time) by as much as 25 percent. This should, in theory, make games run better in general and ease some of the stuttering you notice when your game's performance dips down to that 1 percent level.

Longtime Slashdot reader me34point5 writes: OpenBSD quietly released the new version (7.7) of its "secure by default" operating system. This is the 58th release. Changes include improved hardware and VMM support, along with many kernel improvements. This release brings several specific improvements, including performance boosts on ARM64, Arm SVE support, AMD SEV virtualization enhancements, better low-memory handling on i386, and improved suspend/hibernate and SMP performance. It also updates graphics drivers with support for AMD Ryzen IA 300, Radeon RX 9070, and Intel Arrow Lake, along with expanded hardware support for MediaTek SoCs.

Microsoft Copilot "isn't doing as well as the company would like," reports XDA-Developers.com (citing a report from startup/VC industry site Newcomer). The Redmond giant has invested billions of dollars and a lot of manpower into making it happen, but as a recent report claims, people just don't care. In fact, if the report is to be believed, Microsoft's rise in the AI scene has already come to a screeching halt:

At Microsoft's annual executive huddle last month, the company's chief financial officer, Amy Hood, put up a slide that charted the number of users for its Copilot consumer AI tool over the past year. It was essentially a flat line, showing around 20 million weekly users. On the same slide was another line showing ChatGPT's growth over the same period, arching ever upward toward 400 million weekly users. OpenAI's iconic chatbot was soaring, while Microsoft's best hope for a mass-adoption AI tool was idling. It was a sobering chart for Microsoft's consumer AI team...

That's right; Microsoft Copilot's weekly user base is only 5% of the number of people who use ChatGPT, and it's not increasing. It's also worth noting that there are approximately 1.5 billion Windows users worldwide, which means just over 1% of them are using Copilot, a tool that's now a Windows default app....

It's not a huge surprise that Copilot is faltering. Despite Microsoft's CEO claiming that Copilot will become "the next Start button", the company has had to backtrack on the Copilot key and allow people to customise it to do something else, including giving back its original feature of the Menu key.
They also note earlier reports that Intel's AI PC chips aren't selling well.

Intel is grappling with an unexpected market shift as customers eschew its new AI-focused processors for cheaper previous-generation chips. The company revealed during its recent earnings call that demand for older Raptor Lake processors has surged while its newer, more expensive Lunar Lake and Meteor Lake AI PC chips struggle to gain traction.

This surprising trend, first reported by Tom's Hardware, has created a production capacity shortage for Intel's 'Intel 7' process node that will "persist for the foreseeable future," despite the fact that current-generation chips utilize TSMC's newer nodes. "Customers are demanding system price points that consumers really want," explained Intel executive Michelle Johnston Holthaus, noting that economic concerns and tariffs have affected inventory decisions.

New Intel CEO Lip-Bu Tan has mandated that employees return to the office four days a week starting September 1 to boost collaboration and decision-making. Tan also signaled upcoming job cuts and organizational changes, including a flatter management structure and fewer meetings. "When we spend time together in person, it fosters more engaging and productive discussion and debate," Tan wrote in a note to employees posted on Intel's website Thursday. "It drives better and faster decision-making. And it strengthens our connection with colleagues." Oregon Live reports: Intel factory workers and many researchers are already on site every day, in cleanrooms and labs. But Intel has thousands of employees in corporate roles who have spent at least part of their time working from home since the pandemic. The company adopted a "hybrid-first" approach in 2021, allowing most employees the flexibility to work from home much of the time. More recently, it sought to have workers on site about three days a week.

"Adherence to this policy has been uneven at best," Tan said Thursday. "I strongly believe that our sites need to be vibrant hubs of collaboration that reflect our culture in action." Intel is Oregon's largest corporate employer, with 20,000 employees in the state, so bringing workers back to the office will have a big impact and could set a benchmark for other organizations. [...] On Thursday, Tan said he wants fewer and smaller meetings to free up employees to do their work. He also told employees to expect "several months" of job cuts, but Tan didn't specify how many positions he plans to eliminate.

Intel plans to cut more than 20% of its workforce this week, marking the first major restructuring under new CEO Lip-Bu Tan, according to Bloomberg. The cuts aim to eliminate bureaucracy and restore an engineering-centric culture at the struggling chipmaker. This follows last year's reduction of approximately 15,000 positions, with Intel's headcount already down to 108,900 employees from 124,800 a year earlier.

The Santa Clara-based company has suffered three consecutive years of declining sales while losing technological ground to competitors, particularly Nvidia in the AI computing sector. Tan, who took over last month, has already begun divesting non-core assets, recently selling a 51% stake in Intel's programmable chips unit Altera to Silver Lake.

The Trump administration is "taking measures to restrict the sale of AI chips by Nvidia, Advanced Micro Devices and Intel," especially in China, reports the New York Times. But that's triggered a series of dominoes. "In the two days after the limits became public, shares of Nvidia, the world's leading AI chipmaker, fell 8.4%. AMD's shares dropped 7.4%, and Intel's were down 6.8%." (AMD expects up to $800 million in charges after the move, according to CNBC, while NVIDIA said it would take a quarterly charge of about $5.5 billion.)

The Times notes hopeful remarks Thursday from Jensen Huang, CEO of Nvidia, during a meeting with the China Council for the Promotion of International Trade. "We're going to continue to make significant effort to optimize our products that are compliant within the regulations and continue to serve China's market." But America's chipmakers also have a greater fear, according to the article: "that their retreat could turn the Chinese tech giant Huawei into a global chip-making powerhouse." "For the U.S. semiconductor industry, China is gone," said Handel Jones, a semiconductor consultant at International Business Strategies, which advises electronics companies. He projects that Chinese companies will have a majority share of chips in every major category in China by 2030... Huang's message spoke to one of his biggest fears. For years, he has worried that Huawei, China's telecommunications giant, will become a major competitor in AI. He has warned U.S. officials that blocking U.S. companies from competing in China would accelerate Huawei's rise, said three people familiar with those meetings who spoke on the condition of anonymity.

If Huawei gains ground, Huang and others at Nvidia have painted a dark picture of a future in which China will use the company's chips to build AI data centers across the world for the Belt and Road Initiative, a strategic effort to increase Beijing's influence by paying for infrastructure projects around the world, a person familiar with the company's thinking said...

Nvidia's previous generation of chips perform about 40% better than Huawei's best product, said Gregory C. Allen, who has written about Huawei in his role as director of the Wadhwani AI Center at the Center for Strategic and International Studies. But that gap could dwindle if Huawei scoops up the business of its American rivals, Allen said. Nvidia was expected to make more than $16 billion in sales this year from the H20 in China before the restriction. Huawei could use that money to hire more experienced engineers and make higher-quality chips. Allen said the U.S. government's restrictions also could help Huawei bring on customers like DeepSeek, a leading Chinese AI startup. Working with those companies could help Huawei improve the software it develops to control its chips. Those kinds of tools have been one of Nvidia's strengths over the years.
TechRepublic identifies this key quote from an earlier article: "This kills NVIDIA's access to a key market, and they will lose traction in the country," Patrick Moorhead, a tech analyst with Moor Insights & Strategy, told The New York Times. He added that Chinese companies will buy from local rival Huawei instead.

With macOS now 24 years old and Apple officially designating all Intel-based Mac minis as "vintage" or "obsolete," The Register takes a look at new internet tools that help keep vintage Macs online and surprisingly relevant: Cameron Kaiser of Floodgap Systems is a valuable ally. His retro computing interests are broad, and we've mentioned him a few times on The Register, such as his deep dive into the revolutionary Canon Cat computer, and his evaluation of RISC-V hardware performance. Back in 2020, he revived the native Classic Mac OS port of the Lynx web browser, MacLynx. Earlier this month, he came back to it and has updated it again, including adding native Mac OS dialog boxes. His account is -- as usual -- long and detailed but it's an interesting read. He also maintains some other web browsers for elderly Macs, including TenFourFox for Mac OS X 10.4 and Classilla for Mac OS 8.6 and 9.x.

If you're not up to git pull commands and elderly Mac OS X build tools, then there is a fork of TenFourFox that may be worth a look, InterWebPPC. It's not current with the new batch of patches, but we can still hope for another build. In other "Classic on the internet" news, although it's not a huge amount of use on its own, there's also a newly released Classic Mac OS version of Mbed-TLS on GitHub. This ports the SSL library -- also used in the super-lightweight Dillo browser -- to the older C89/C90 standard, so that it can build in CodeWarrior and run with OpenTransport from Mac OS 9 right back to later versions of Mac OS 7.

Modern macOS is UNIX certified and as such it's not all that dissimilar from other Unix-like OSes, such as Linux and the BSD family. Classic Mac OS is a profoundly different beast, which makes porting modern code to it a complex exercise -- but equally, it's a good learning exercise, and we're delighted to see 21st century programmers exploring this 1980s OS. That may be part of the motivation behind the newly announced and still incomplete SDL 2 "rough draft" that appeared a week ago. It builds on the existing SDL 1.2 port, but so far, it's less complete -- for instance, there's no sound support.

Canonical today released Ubuntu 25.04 "Plucky Puffin," bringing significant upgrades to the non-LTS distribution including Linux kernel 6.14, GNOME 48 with triple buffering, and expanded hardware support.

For the first time, Ubuntu ships an official generic ARM64 desktop ISO targeting virtual machines and Snapdragon-based devices, with initial enablement for the Snapdragon X Elite platform. The release also adds full support for Intel Core Ultra Xe2 integrated graphics and "Battlemage" discrete GPUs, delivering improved ray tracing performance and hardware-accelerated video encoding.

Networking improvements include wpa-psk-sha256 Wi-Fi support and enhanced DNS resolution detection. The installer now better handles BitLocker-protected Windows partitions for dual-boot scenarios. Other notable changes include JPEG XL support by default, NVIDIA Dynamic Boost enabled on supported laptops, Papers replacing Evince as the default document viewer, and APT 3.0 becoming the standard package manager. Ubuntu 25.04 will receive nine months of support until January 2026.

Apple has officially designated all Intel-based Mac minis as "vintage" or "obsolete," marking the end of an era. This means Apple no longer guarantees parts or service for these devices, as they've surpassed the 5- to 7-year support window. 9to5Mac reports: Apple periodically adds devices to its ever-growing list of vintage and obsolete products. That happened today, as spotted by MacRumors, with two noteworthy "vintage" additions: iPhone 6s and Mac mini (2018). The latter product is especially significant, because the 2018 Mac mini was the last remaining Intel model that was not yet labeled either vintage or obsolete.

So what are those timelines exactly? Per Apple's definitions: Vintage: "Apple stopped distributing them for sale more than 5 and less than 7 years ago." Obsolete: "Apple stopped distributing them for sale more than 7 years ago." [...] Since these products are now considered vintage, Apple no longer guarantees that parts for repairs will be readily available.

Intel will sell a 51% stake in its Altera programmable chip unit to private equity firm Silver Lake for $4.46 billion, aiming to cut costs, raise cash, and streamline the company's focus as it shifts toward becoming a contract chip manufacturer. CNBC reports: The deal, announced on Monday, values Altera at $8.75 billion, a sharp decline from the $17 billion Intel paid in 2015. [...] Since last year, Intel has taken steps to spin Altera out as a separate unit and said it planned to sell a portion of its stake. "Today's announcement reflects our commitment to sharpening our focus, lowering our expense structure and strengthening our balance sheet," [CEO Lip-Bu Tan], who took the helm after former top boss Pat Gelsinger's ouster, said.

Altera makes programmable chips that can be used for various purposes from telecom equipment to military. Reuters had first reported in November that Silver Lake was among potential suitors competing for a minority stake in Altera. The deal is expected to close in the second half of 2025, after which Intel expects to deconsolidate Altera's financial results from Intel's financial statements, the company said.

"AMD processors were instrumental in achieving a new world record," reports Tom's Hardware, "during a recent Ansys Fluent computational fluid dynamics simulation run on the Frontier supercomputer at the Oak Ridge National Laboratory."

The article points out that Frontier was the fastest supercomputer in the world until it was beaten by Lawrence Livermore Lab's El Capitan — with both computers powered by AMD GPUs: According to a press release by Ansys, it ran a 2.2-billion-cell axial turbine simulation for Baker Hughes, an energy technology company, testing its next-generation gas turbines aimed at increasing efficiency. The simulation previously took 38.5 hours to complete on 3,700 CPU cores. By using 1,024 AMD Instinct MI250X accelerators paired with AMD EPYC CPUs in Frontier, the simulation time was slashed to 1.5 hours. This is more than 25 times faster, allowing the company to see the impact of the changes it makes on designs much more quickly...

Given those numbers, the Ansys Fluent CFD simulator apparently only used a fraction of the power available on Frontier. That means it has the potential to run even faster if it can utilize all the available accelerators on the supercomputer. It also shows that, despite Nvidia's market dominance in AI GPUs, AMD remains a formidable competitor, with its CPUs and GPUs serving as the brains of some of the fastest supercomputers on Earth.

Coreboot 25.03 has been released with support for 22 new motherboards and several other significant updates, including enhanced display handling, USB debugging, RISC-V support, and RAM initialization for older Intel platforms. Phoronix reports: Coreboot 25.03 delivers display handling improvements, a better USB debugging experience, CPU topology updates, various improvements to the open-source RAM initialization for aging Intel Haswell platforms, improved USB Type-C and Thunderbolt handling, various embedded controller (EC) improvements, better RISC-V architecture support, DDR5-7500 support, and many bug fixes across the sprawling Coreboot codebase. More details, including a full list of the supported boards, can be found here.

Intel and Taiwan Semiconductor Manufacturing Co. have reached a preliminary agreement to form a joint venture operating Intel's chipmaking facilities, with TSMC taking a 20% stake, The Information reports [non-paywalled source]. Intel and other U.S. semiconductor companies would hold the majority of shares in the proposed venture. Instead of capital investment, TSMC has discussed sharing chipmaking methods and training Intel personnel.

The talks face internal opposition from some Intel executives concerned about widespread layoffs and the abandonment of Intel's own technology, according to the report. The deal could help TSMC neutralize a struggling competitor while potentially giving Taiwan more leverage with the U.S. administration, which recently imposed tariffs on Taiwanese goods excluding chips.

Intel has unveiled a refresh of its iconic brand identity, introducing the slogan "That's the power of Intel Inside" to reconnect with consumers and highlight the chipmaker's role in modern computing. The new campaign resurrects the familiar "Intel Inside" theme that helped transform the company into a household name in the 1990s, when Intel's marketing strategy directly targeted consumers rather than system designers.

Brett Hannath, Intel's chief marketing officer, said the message reflects the company's belief that its products can unlock potential for employees, customers, consumers and partners. The original "Intel Inside" campaign, launched in 1991, revolutionized tech marketing by making processors a key selling point for PCs with its recognizable sticker and five-note jingle. The strategy helped Intel differentiate itself from competitors like AMD and Cyrix during the PC market explosion.

Despite promises of more efficient streaming, the AV1 video codec hasn't achieved widespread adoption seven years after its 2018 debut, even with backing from tech giants Netflix, Microsoft, Google, Amazon, and Meta. The Alliance for Open Media (AOMedia) claims AV1 is 30% more efficient than standards like HEVC, delivering higher-quality video at lower bandwidth while remaining royalty-free.

Major services including YouTube, Netflix, and Amazon Prime Video have embraced the technology, with Netflix encoding approximately 95% of its content using AV1. However, adoption faces significant hurdles. Many streaming platforms including Max, Peacock, and Paramount Plus haven't implemented AV1, partly due to hardware limitations. Devices require specific decoders to properly support AV1, though recent products from Apple, Nvidia, AMD, and Intel have begun including them. "In order to get its best features, you have to accept a much higher encoding complexity," Larry Pearlstein, associate professor at the College of New Jersey, told The Verge. "But there is also higher decoding complexity, and that is on the consumer end."
