Microsoft is announcing today that it won't block people from installing Windows 11 on most older PCs. While the software maker has recommended hardware requirements for Windows 11 -- which it's largely sticking to -- a restriction to install the OS will only be enforced when you try to upgrade from Windows 10 to Windows 11 through Windows Update. From a report: This means anyone with a PC with an older CPU that doesn't officially pass the upgrade test can still go ahead and download an ISO file of Windows 11 and install the OS manually. Microsoft announced its Windows 11 minimum hardware requirements in June, and made it clear that only Intel 8th Gen and beyond CPUs were officially supported. Microsoft now tells us that this install workaround is designed primarily for businesses to evaluate Windows 11, and that people can upgrade at their own risk as the company can't guarantee driver compatibility and overall system reliability. Microsoft won't be recommending or advertising this method of installing Windows 11 to consumers.

Tom's Hardware reports: Based on revenue, Samsung Electronics has reclaimed the number one semiconductor manufacturer spot on the back of a strong Q2 2021, according to the latest IC Insight's The McClean Report, which investigates the state of the semiconductor industry in several areas.

The South Korean company achieved a 19 percent increase in overall IC sales compared to Q1 2021, bringing in a total of $20.29 billion in the April-June period alone... On the other hand, Intel achieved a smaller three percent QoQ (Quarter-over-Quarter) increase that resulted in a cool $19.3 billion in chip sales. For reference, AMD, which is generally considered to have a competitive CPU portfolio compared to Intel, brought in a comparatively measly $3.85 billion...

According to the present-day report, Samsung has achieved the top spot mainly due to ascending ASP (Average Sale Price) of NAND and DRAM, with the latter being a significant high-volume advantage over Intel, which doesn't produce RAM. Samsung had last been the top manufacturer back in Q3 2018 — again on the back of strong NAND and DRAM results in the midst of a market shortage.

Internet infrastructure company Cloudflare disclosed today that it mitigated the largest volumetric distributed denial of service attack that was recorded to date. From a report: The attack, which took place last month, targeted one of Cloudflare's customers in the financial industry. Cloudflare said that a threat actor used a botnet of more than 20,000 infected devices to flung HTTP requests at the customer's network in order to consume and crash server resources.

Called a volumetric DDoS, these are different from classic bandwidth DDoS attacks where threat actors try to exhaust and clog up the victim's internet connection bandwidth. Instead, attackers focus on sending as many junk HTTP requests to a victim's server in order to take up precious server CPU and RAM and prevent legitimate users from using targeted sites. Cloudflare said this attack peaked at 17.2 million HTTP requests/second (rps), a figure that the company described as almost three times larger than any previous volumetric DDoS attack that was ever reported in the public domain.

Intel has spent much of 2021 announcing plans for its future: a new IDM 2.0 strategy, new naming schemes for its process nodes, and new desktop GPUs. At Intel's Architecture Day 2021, we finally got a preview of how some of those changes are coming together in new chips, starting with the upcoming Alder Lake lineup later this year. From a report: As the company has been teasing since last year's Architecture Day, Alder Lake will feature Intel's latest hybrid architecture: instead of simply offering the next generation of powerful Intel CPU cores, it'll offer a mix of both performance and efficiency x86 cores, both of which Intel previewed as part of its announcements. Additionally, Alder Lake will be the first chip released on Intel's newly renamed Intel 7 technology node (not to be confused with Intel 4, which was previously known as Intel's delayed 7nm node, and will be available to consumers sometime in 2023 under the codename "Meteor Lake"). Intel 7 still uses similar technology to the company's current 10nm tech, instead of the bigger leap in manufacturing processes planned for Intel 4.

The new x86 performance core -- codenamed "Golden Cove" -- is the successor to the Willow Cove cores that are currently found in the company's 11th Gen Tiger Lake processors. Intel claims that it's the most powerful CPU core its ever built, but the company only offered a comparison to its Cypress Cove cores (the version of its 10nm architecture that Intel ported to its 14nm process), not the more advanced Willow Cove cores. Meanwhile, the company's new x86 Efficient core (codenamed "Gracemont") aims to be "the world's most efficient x86 CPU core" while still offering higher IPC than the company's Skylake chips. Intel claims that for single-thread cases, one of its new efficient cores hits 40 percent more performance at the same power (or similar performance while using 40 percent of the power) of a Skylake core, improvements that double when comparing four Efficient cores running four threads to two Skylake cores running four threads.

The Register's Richard Speed commemorates the 40th anniversary of the introduction of the IBM Model 5150: IBM was famously late to the game when the Model 5150 (or IBM PC) put in an appearance. The likes of Commodore and Apple pretty much dominated the microcomputer world as the 1970s came to a close and the 1980s began. Big Blue, on the other hand, was better known for its sober, business-orientated products and its eyewatering price tags. However, as its customers began eying Apple products, IBM lumbered toward the market, creating a working group that could dispense with the traditional epic lead-times of Big Blue and take a more agile approach. A choice made was to use off-the-shelf hardware and software and adopt an open architecture. A significant choice, as things turned out.

Intel's 8088 was selected over the competition (including IBM's own RISC processor) and famously, Microsoft was tapped to provide PC DOS as well as BASIC that was included in the ROM. So this marks the 40th anniversary of PC DOS, aka MS-DOS, too. You can find Microsoft's old MS-DOS source code here. The basic price for the 5150 was $1,565, with a fully loaded system rising to more than $3,000. Users could enjoy high resolution monochrome text via the MDA card or some low resolution graphics (and vaguely nauseating colors) through a CGA card (which could be installed simultaneously.) RAM landed in 16 or 64kB flavors and could be upgraded to 256kB while the Intel 8088 CPU chugged along at 4.77 MHz.

Storage came courtesy of up to two 5.25" floppy disks, and the ability to attach a cassette recorder -- an option swiftly stripped from later models. There was no hard disk, and adding one presented a problem for users with deep enough pockets: the motherboard and software didn't support it and the power supply was a bit weedy. IBM would resolve this as the PC evolved. Importantly, the motherboard also included slots for expansion, which eventually became known as the Industry Standard Architecture (ISA) bus as the IBM PC clone sector exploded. IBM's approach resulted in an immense market for expansion cards and third party software. While the Model 5150 "sold like hotcakes," Speed notes that it was eventually discontinued in 1987.

Uptycs Threat Research Team has discovered malware that not only hijacks vulnerable *nix-based servers and uses them to mine cryptocurrency but actually modifies their CPU configurations in a bid to increase mining performance at the cost of performance in other applications. Tom's Hardware reports: Perpetrators use a Golang-based worm to exploit known vulnerabilities like CVE-2020-14882 (Oracle WebLogic) and CVE-2017-11610 (Supervisord) to gain access to Linux systems, reports The Record. Once they hijack a machine, they use model-specific registers (MSR) to disable the hardware prefetcher, a unit that fetches data and instructions from the memory into the L2 cache before they are needed.

Prefetching has been used for years and can boost performance in various tasks. However, disabling it can increase mining performance in XMRig, the mining software the perpetrators use, by 15%. But disabling the hardware prefetcher lowers performance in legitimate applications. In turn, server operators either have to buy additional machines to meet their performance requirements or increase power limits for existing hardware. In either case, they increase power consumption and spend additional money. The botnet has been reportedly used since at least December 2020 and targeted vulnerabilities in MySQL, Tomcat, Oracle WebLogic, and Jenkins.

An anonymous reader quotes a report from Ars Technica: Google is cooking up the first major Wear OS release since 2018, and Samsung is abandoning Tizen for smartwatches and going all-in on Wear OS with the Galaxy Watch 4. Last night, Samsung took the wraps off the main SoC for the Galaxy Watch 4, and compared to what Wear OS usually gets, Samsung is shipping a beast of an SoC. The "Samsung Exynos W920" will be a multi-generational leap in performance for Wear OS. Samsung says this is a 5 nm chip with two ARM Cortex A55 cores and an ARM Mali-G68 GPU. For the always-on display mode, there's an additional Cortex M55 CPU, which can keep the watch face ticking along while using minimal power. There's also an integrated LTE modem for on-the-go connectivity.

Compared to Samsung's previous smartwatch chip, the Tizen-only Exynos 9110 (10 nm, 2x Cortex A53), the company is promising "around 20 percent" better CPU performance and "ten times better graphics performance." Remember that the Exynos 9110 is from 2018, so those comparative numbers are inflated, but at 5 nm, this is a more modern chip than Wear OS has ever seen. Wear OS has suffered for years at the hands of Qualcomm, which has been starving the ecosystem of quality SoCs for wearables. Most people's last experience with Wear OS is the Snapdragon Wear 2100 or 3100 SoCs, both of which were ancient Cortex A7 CPUs built on a 28 nm process. Qualcomm introduced a slightly more modern chip, the Wear 4100 in 2020 (a Cortex A53-based, 12 nm chip), but almost no manufacturers actually shipped that chip a year later, and we're still getting Wear 3100 launches today. Qualcomm's answer to Samsung's chip will be the Wear 5100, which isn't due until 2022. We should know more about Wear OS 3.0 tomorrow when Samsung holds its Aug. 11 "Unpacked" event. Not only are they expected to reveal the Galaxy Watch 4 and the big Wear OS revamp, but they're planning to launch at least two new foldable smartphones -- the Galaxy Z Fold 3 and Galaxy Z Flip 3.

Microsoft launched its new cloud PC Windows 365 service earlier this week, and the company has already had to pause free trials due to demand. From a report: Windows 365 lets you rent a cloud PC -- with a variety of CPU, RAM, and storage options -- and then stream Windows 10 or Windows 11 via a web browser. The service reached max capacity after only a day of signups. "Following significant demand, we have reached capacity for Windows 365 trials," reads a statement from the Microsoft 365 Twitter account. "We have seen unbelievable response to Windows 365 and need to pause our free trial program while we provision additional capacity," explains Scott Manchester, director of Windows 365 program management.

MojoKid writes: AMD is taking the wraps off of its latest integrated processors known as Ryzen 7 5700G and the Ryzen 5 5600G. As their branding suggests, these new products are based on the same excellent AMD Zen 3 core architecture, but with integrated graphics capabilities on board as well, hence the "G" designation. AMD is targeting more mainstream applications with these chips. The Ryzen 7 5700G is an 8-core/16-thread CPU with 4MB of L2 cache and 16MB of L3. Those CPU cores are mated to an 8 CU (Compute Unit) Radeon Vega graphics engine, and it has 24 lanes of PCIe Gen 3 connectivity. The 5700G's base CPU clock is 3.8GHz, with a maximum boost clock of 4.6GHz. The on-chip GPU can boost up to 2GHz, which is a massive uptick from the 1.4GHz of previous-gen 3000-series APUs.

The Ryzen 5 5600G takes things down a notch with 6 CPU cores (12 threads) and a smaller 3MB L2 cache while L3 cache size remains unchanged. The 5600G's iGPU is scaled down slightly as well with only 7 CUs. At 3.9GHz, the 5600G's base CPU clock is 100MHz higher than the 5700G's, but its max boost lands at 4.4GHz with a slightly lower GPU boost clock of 1.9GHz. In the benchmarks, the Ryzen 5 5600G and Ryzen 7 5700G both offer enough multi-threaded muscle for the vast majority of users, often besting similar Intel 11th Gen Core series chips, with highly competitive single-thread performance as well.

Along with other optimizations to benefit the Steam Deck, AMD and Valve have been jointly working on CPU frequency/power scaling improvements to enhance the Steam Play gaming experience on modern AMD platforms running Linux. Phoronix reports: It's no secret that the ACPI CPUFreq driver code has at times been less than ideal on recent AMD processors with delivering less than expected performance/behavior with being slow to ramp up to a higher performance state or otherwise coming up short of disabling the power management functionality outright. AMD hasn't traditionally worked on the Linux CPU frequency scaling code as much as Intel does to their P-State scaling driver and other areas of power management at large. AMD is ramping up efforts in these areas including around the Linux scheduler given their recent hiring spree while it now looks like thanks to the Steam Deck there is renewed interest in better optimizing the CPU frequency scaling under Linux.

AMD and Valve have been working to improve the performance/power efficiency for modern AMD platforms running on Steam Play (Proton / Wine) and have spearheaded "[The ACPI CPUFreq driver] was not very performance/power efficiency for modern AMD platforms...a new CPU performance scaling design for AMD platform which has better performance per watt scaling on such as 3D game like Horizon Zero Dawn with VKD3D-Proton on Steam." AMD will be presenting more about this effort next month at XDC. It's quite possible this new effort is focused on ACPI CPPC support with the previously proposed AMD_CPUFreq. Back when Zen 2 launched in 2019, AMD did post patches for their new CPUFreq driver that leveraged ACPI Collaborative Processor Performance Controls but the driver was never mainlined nor any further iterations of the patches posted. When inquiring about that work a few times since then, AMD has always said it's been basically due to resource constraints that it wasn't a focus at that time. Upstream kernel developers also voiced their preference to seeing AMD work to improve the generic ACPI CPPC CPUFreq driver code rather than having another vendor-specific solution. It's also possible AMD has been working on better improvements around the now-default Schedutil governor for scheduler utilization data in making CPU frequency scaling decisions.

Google announced Monday it will build its own smartphone processor, called Google Tensor, that will power its new Pixel 6 and Pixel 6 Pro phones this fall. From a report: It's another example of a company building its own chips to create what it felt wasn't possible with those already on the market. In this case, Google is ditching Qualcomm. The move follows Apple, which is using its own processors in its new computers instead of Intel chips. And like Apple, Google is using an Arm-based architecture. Arm processors are lower power and are used across the industry for mobile devices, from phones to tablets and laptops.

Google Tensor will power new flagship phones that are expected to launch in October. (Google will reveal more details about those phones closer to launch.) That, too, is a strategy shift for Google, which in recent years has focused on affordability in its Pixel devices instead of offering high-end phones. And it shows that Google is again trying to compete directly in the flagship space against Apple and Samsung. The name Google Tensor is a nod to the name of Google's Tensor Processing Unit the company uses for cloud computing. It's a full system on a chip, or SoC, that the company says will offer big improvements to photo and video processing on phones, along with features like voice-to-speech and translation. And it includes a dedicated processor that runs artificial intelligence applications, in addition to a CPU, GPU and image signal processor. It will allow the phone to process more information on the device instead of having to send data to the cloud. Further reading: Google's New Pixel Phones Features a Processor Designed In-House.

Valve expects that its recently announced Steam Deck portable gaming console will be able to run "really the entire Steam library" on its 1280x800 LCD screen at frame rates of 30 fps or higher. Ars Technica reports: That's according to a recent IGN video interview in which Valve Hardware Engineer Yazan Aldehayyat said that "all the games that we wanted to be playable had really good [performance], a really good experience" in Steam Deck testing. Valve developer Pierre-Loup Griffais expanded on that statement by saying that "all the games that we wanted to be playable" means "really the entire Steam library." "We haven't really found something we could throw at this device that it couldn't handle yet," he added.

Griffais said initial prototype testing for the Steam Deck focused on older games in the Steam catalog and that there were "games that were coming out last year that just couldn't really run very well on the previous types of prototypes and architectures we were testing." On the finalized version of the hardware, though, he said the company has "achieved the level of performance that is required to run the latest generation of games without a problem." "The entire Steam catalog is available to people who have this device," Aldehayyat added. "That's where we knew we had a product that was going to deliver the experience we were looking for."

Aldehayyat attributed Steam Deck's wide compatibility in part to "future-proofing" internals that include a custom APU incorporating AMD's latest generation of GPU and CPU technology, as well as 16GB of LPDDR5 RAM. Griffais added that the performance scalability of modern PC games helps Steam Deck achieve a playable frame rate at its native 800p resolution (which is relatively low compared to desktop gaming PCs). "If people are still valuing high frame rates and high resolutions on different platforms, I think that content will scale down to our 800p, 30 Hz target very well," he said. "If people start heavily favoring image quality, we might be in a position where we might have tradeoffs, but we're not in a position where we really see that yet." In a follow-up tweet late last week, Griffais clarified that the 30 fps target is the "floor" for what Valve considers playable: "games we've tested and shown have consistently met and exceeded that bar so far. There will also be an optional built-in FPS limiter to fine-tune perf[ormance] vs. battery life."

"Are you old enough to remember when laptops had removable batteries?" asks CNET. "Frustrated by mainstream laptops with memory soldered to the motherboard and therefore not upgradable?"

"The 13.5-inch Framework Laptop taps into that nostalgia, addressing one of the biggest drawbacks in modern laptops as part of the right-to-repair movement. It was designed from the ground up to be as customizable, upgradable and repairable as technologically possible... and boy does it deliver." It features four expansion card slots, slide-in modules that snap into USB-C connectors, socketed storage and RAM, a replaceable mainboard module with fixed CPU and fan, battery, screen, keyboard and more. It's a design that makes the parts easy to access, all while delivering solid performance at competitive prices and without sacrificing aesthetics.

The laptop's in preorder now for the U.S. and Canada, slated to ship in small batches depending upon the configuration. Core i7-based systems are expected to go out in August, while Core i5 systems won't be available until September. Prices for the Framework Laptop start at $999 for the prefab Core i5-1135G7 model with 8GB RAM and 256GB SSD, $1,399 for the Core i7-1165G7 Performance model with 16GB RAM and 512GB storage or a vPro Core i7-1185G7 Professional model with 32GB RAM and 1TB storage. Framework expects to expand into new regions by the end of the year; $999 converts to roughly £730 or AU$1,360... The DIY model adds Linux to the list of operating systems you can install, and doesn't restrict Windows Pro to the vPro model...

With the Framework, in addition to the ports you can swap out the mainboard, touchpad, keyboard, speakers, battery... anything you can think of. Don't feel like doing it yourself? Framework is publishing all the information necessary for a repair shop or IT department to not just swap parts, but to perform repairs... Nothing is buried under other parts, so everything's easy to get to. Each Framework part has a QR code and short URL to take you to all the info you'll need about it and the labels on the standard parts (memory and SSD) are easy to read.
Or, as Engadget puts it, the laptop is "designed, from the get-go, to be modular and repairable by every one of its users." Created by Nirav Patel, formerly of Oculus, the machine aims to demonstrate that there is a better, more sustainable way of doing things. It shouldn't be that, if your tech fails, you either have to buy a new model, or let the manufacturer's in-house repair teams charge $700 for a job that should've cost $50 . After all, if we're going to survive climate change, we need to treat our tech more sustainably and keep as much as possible out of the landfill...

The Framework laptop is equipped with a 1080p, 60fps webcam with an 80-degree field of view, and it's one of the best built-in webcams I've seen.
PCWorld calls it "the ultimate Right to Repair laptop."

"This week, a 22-year-old self-described Bitcoin millionaire introduced the Freedom Phone, a $499 device meant to be completely free from 'Big Tech's' censorship and influence," reports PC Magazine.

"But it turns out the same smartphone is actually from China, and probably just a cheap knock-off." The Freedom Phone comes from Erik Finman, who unveiled the device earlier this week. He claims the product has everything Trump supporters could dream of, including an "uncensorable" app store, preinstalled conservative-friendly apps including Parler and Rumble, and even its own anti-surveillance operating system called FreedomOS... However, The Daily Beast noticed the Freedom Phone looks strikingly similar to a budget smartphone device from a Chinese vendor called Umidigi. The device is called the Umidigi A9 pro, and you can actually buy it over on the Chinese e-commerce site AliExpress starting at $119. Finman later told The Daily Beast that the Freedom Phone was indeed sourced from Umidigi, a company that's based in Shenzhen, China...

An uncensorable app store opens the door for hackers and shady developers to circulate malware and data-collecting programs to users. We're also doubtful Freedom Phone has its own operating system if it can run apps such as Parler and Rumble, in addition to Signal, Telegram and Brave
The Daily Beast adds this anecdote: The Freedom Phone's "Freedom OS" operating system is based on Google's Android operating system, according to Finman. But during a livestream video promoting the phone, right-wing activist Anna Khait was confused by her fans' basic questions about the phone. "Is it an Android?" Khait said. "I'm not really sure. No, it's a Freedom Phone."
Gizmodo calls the phone's web site "radically vague on the details." There is no information about the phone's operating system, storage, camera, CPU, or RAM capabilities. It has a list of features, but there are no actual details about them. Instead, under each feature, there's merely a "Buy it now" button which redirects you to the site's shopping cart. The phone's hefty price, combined with the company's total lack of transparency, is ridiculous — essentially asking the buyer to cough up half a grand in exchange for, uh, something...!
But Gizmodo also shares a philosophical thought: Before we get into the specifics of why this device probably sucks, let me just say that the desire to have a phone that is dedicated to protecting your autonomy and privacy is a reasonable one — and should be encouraged. That said, I don't think the Freedom Phone provides that. Actually, aside from its overt partisan bent, it's impossible to tell what kind of device this is because Finman and his acolytes haven't provided any information about it...

The funny thing is, if Trump voters are looking for a way to get off the "Big Tech" grid, there's no need for them to buy this sketchy shit. There are actually entire subcultures within the phone industry dedicated to escaping the Android/iOS paradigm. You can wade into the de-Googled phone sector, for instance — where Android phones are sold that have ostensibly been refurbished to rid the devices of code that will "send your personal data" back to the tech giant. There's also the Linux-based Pinephone, which sells at a fraction of the Freedom Phone's cost (between $150 and $200), and is a favorite of those in the privacy community. All of these come with caveats, obviously, but the point is that there are much more transparent and affordable options than the Freedom Phone...

It'd be nice if Americans could actually come together around the issue of privacy since it's an area where — regardless of political party — we're all collectively getting screwed.

A new challenger has emerged in the gaming hardware category. Game distribution giant Valve today announced the launch of Steam Deck, a $399 gaming portable designed to take PC games on the go. From a report: The handheld (which has echoes of several portable gaming rigs of years past) features a seven-inch screen and runs on a quad-core Zen 2 CPU, coupled with AMD RDNA 2 graphics and 16GB of RAM. Storage runs 64GB to 512GB, the latter of which bumps the price up to $649. The built-in storage can be augmented via microSD.

[...] Flanking the 1280 x 800 touchscreen are a pair of trackpads and thumb sticks. A built-in gyroscope also uses movement to control the gaming experience. There's a single USB-C port for charging, peripherals and connecting to a big screen, while a 40Wh battery promises between 7-8 hours of gameplay, by Valve's numbers.

Anyone deciding to download the free and open-source audio editor Audacity is being warned that the software may now be classified as spyware due to recent updates to its privacy policy. From a report: Audacity has been around for over 21 years and classes as the world's most popular audio editing software. On April 30, the Muse Group acquired Audacity with the promise that the software would "remain forever free and open source." However, as FOSS Post reports, last week the Audacity privacy policy page was updated and introduced a number of personal data collection clauses. The data collected includes OS version and name, user country based on IP address, the CPU being used, data related to Audacity error codes and crash reports, and finally "Data necessary for law enforcement, litigation and authorities' requests (if any)." The personal data collected can be shared with Muse Group employees, auditors, advisors, legal representatives and "similar agents," potential company buyers, and "any competent law enforcement body, regulatory, government agency, court or other third party where we believe disclosure is necessary (i) as a matter of applicable law or regulation, or (ii) to exercise, establish or defend our legal rights."
UPDATE: Ars Technica's Jim Salter disagrees, pointing out that "neither the privacy policy nor the in-app telemetry in question are actually in effect yet," and that the company now plans to self-host its telemetry sessions rather than using third-party libraries and hosting.

Intel has delayed production of its next-generation Xeon Scalable CPUs, code-named Sapphire Rapids, to the first quarter of 2022 and said it will start ramping shipments by at least April of next year. From a report: The Santa Clara, Calif.-based company disclosed the delay in a Tuesday blog post by Lisa Spelman, head of Intel's Xeon and Memory Group, who teased the CPU's new microarchitecture as well as two features that will be new to the Xeon lineup: the next generation of Deep Learning Boost and an acceleration engine called Intel Data Streaming Accelerator. Spelman said Intel is delaying Sapphire Rapids, the 10-nanometer successor to the recently launched Ice Lake server processors, because of extra time needed to validate the CPU.

Intel is going to be disabling Transactional Synchronization Extensions (TSX) by default for various Skylake through Coffee Lake processors with forthcoming microcode updates. Phoronix reports: Transactional Synchronization Extensions (TSX) have been around since Haswell for hardware transactional memory support and going off Intel's own past numbers can be around 40% faster in specific workloads or as much 4~5 times faster in database transaction benchmarks. TSX issues have been found in the past such as a possible side channel timing attack that could lead to KASLR being defeated and CVE-2019-11135 (TSX Async Abort) for an MDS-style flaw. Now in 2021 Intel is disabling TSX by default across multiple families of Intel CPUs from Skylake through Coffee Lake. [...] The Linux kernel is preparing for this microcode change as seen in the flow of new patches this morning for the 5.14 merge window.

A memory ordering issue is what is reportedly leading Intel to now deprecate TSX on various processors. There is this Intel whitepaper (PDF) updated this month that outlines the problem at length. As noted in the revision history, the memory ordering issue has been known to Intel since at least before October 2018 but only now in June 2021 are they pushing out microcode updates to disable TSX by default. With forthcoming microcode updates will effectively deprecate TSX for all Skylake Xeon CPUs prior to Stepping 5 (including Xeon D and 1st Gen Xeon Scalable), all 6th Gen Xeon E3-1500m v5 / E3-1200 v5 Skylake processors, all 7th/8th Gen Core and Pentium Kaby/Coffee/Whiskey CPUs prior to 0x8 stepping, and all 8th/9th Gen Core/Pentium Coffee Lake CPUs prior to 0xC stepping will be affected. That ultimately spans from various Skylake steppings through Coffee Lake; it was with 10th Gen Comet Lake and Ice Lake where TSX/TSX-NI was subsequently removed.

In addition to disabling TSX by default and force-aborting all RTM transactions by default, a new CPUID bit is being enumerated with the new microcode to indicate that the force aborting of RTM transactions. It's due to that new CPUID bit that the Linux kernel is seeing patches. Previously Linux and other operating systems applied a workaround for the TSX memory ordering issue but now when this feature is disabled, the kernel can drop said workaround. These patches are coming with the Linux 5.14 cycle and will likely be back-ported to stable too.

Slashdot reader thegarbz writes: While a lot of focus has been on the TPM requirements for Windows 11, Microsoft has since updated its documentation to provide a complete list of supported processors. At present the list includes only Intel 8th Generation Core processors or newer, and AMD Ryzen Zen+ processors or newer, effectively limiting Windows 11 to PC less than 4-5 years old.

Notably absent from the list is the Intel Core i7-7820HQ, the processor used in Microsoft's current flagship $3500+ Surface Studio 2. This has prompted many threads on Reddit from users angry that their (in some cases very new) Surface PC is failing the Windows 11 upgrade check.
The Verge confirms: Windows 11 will only support 8th Gen and newer Intel Core processors, alongside [Intel's 2016-era] Apollo Lake and newer Pentium and Celeron processors. That immediately rules out millions of existing Windows 10 devices from upgrading to Windows 11... Windows 11 will also only support AMD Ryzen 2000 and newer processors, and 2nd Gen or newer [AMD] EPYC chips. You can find the full list of supported processors on Microsoft's site...

Originally, Microsoft noted that CPU generation requirements are a "soft floor" limit for the Windows 11 installer, which should have allowed some older CPUs to be able to install Windows 11 with a warning, but hours after we published this story, the company updated that page to explicitly require the list of chips above.

Many Windows 10 users have been downloading Microsoft's PC Health App (available here) to see whether Windows 11 works on their systems, only to find it fails the check... This is the first significant shift in Windows hardware requirements since the release of Windows 8 back in 2012, and the CPU changes are understandably catching people by surprise.

Microsoft is also requiring a front-facing camera for all Windows 11 devices except desktop PCs from January 2023 onwards.
"In order to run Windows 11, devices must meet the hardware specifications," explains Microsoft's official compatibility page for Windows 11.

"Devices that do not meet the hardware requirements cannot be upgraded to Windows 11."
