An anonymous reader shares a report: The first few months of 2021 have been absolutely massive for AMD and Intel. According to the latest report from Mercury Research, the first three months of 2021 saw the largest yearly increase in shipments of CPUs in a quarter of a century, and second only to the final moments of 2020 in terms of raw volume. You'd be perhaps surprised to learn that Intel has gained a touch in overall x86 market share in Q1 2021, whereas AMD reportedly lost out. There's only a percentage point in it: a 1% gain for Intel and a 1% loss for AMD, though. Far from major gains in either direction.

Mercury Research puts that down to an increase in budget chip shipments for Chipzilla, which tallies with other figures out of the tech giant as of late. But where Intel has gained in mobile processor market share, it loses out marginally in desktop. That's where AMD's Ryzen processors are seemingly crushing it, and despite some difficulty sourcing the top-tier chips, such as the Ryzen 9 5950X and Ryzen 9 5900X, AMD is still managing to make gains within the market predisposed to Intel processors for so long. [...] But perhaps the biggest win in AMD's eyes is the 1.8% increase in server market share quarter to quarter, and 3.8 percent year on year. That means its Epyc processors are selling supremely well against Intel's Xeon chips, and the market that AMD will be most determined to get more of a footing in.

CES 2022 is going back to Las Vegas following this year's all-digital event, the Consumer Technology Association said Thursday, as coronavirus restrictions ease in the US. The event will take place Jan. 5-8, with media days taking place Jan. 3-4. From a report: Around 1,000 companies -- including Amazon, AMD, AT&T, Daimler AG, Dell, Google, Hyundai, IBM, Intel, Lenovo, LG, Panasonic, Qualcomm, Samsung and Sony -- are on board for the event, according to the CTA, with more being added. You'll also be able to attend digitally. Plans for the event will evolve depending on coronavirus safety measures from the Centers for Disease Control and Prevention, the CTA noted.

Microsoft on Tuesday announced a new 2021 Surface Laptop, called the Surface Laptop 4. The new version adds 11th-gen Intel Core processors, paired with Intel Iris XE graphics. There's also an AMD processor option -- Zen 2 series -- with a graphics chip called AMD Radeon Graphics Microsoft Surface Edition. From a report: For all the buzz Microsoft's Surface tablets get, I've always thought the Surface Laptop was actually Microsoft's secret weapon. Since Surface Laptop debuted in 2017, it's been a strong contender for the best all-purpose slim Windows laptop. But plenty of companies offer 13-inch-class slim laptops, all hoping to be the Windows version of Apple's ubiquitous MacBook Air. (Microsoft also introduced a 15-inch version in 2019.) Microsoft says the Surface Laptop has the Surface line's highest level of customer satisfaction. Besides simply working well and being stylish and easy to use, the Surface Laptop was frequently on sale at very reasonable prices, making it a great way to get a rock-solid clamshell laptop for not much money. Shortly before the Surface Laptop 4 preorders went live, you could still order a Core i5 13-inch Surface Laptop 3 (with 8GB RAM and a 128GB SSD) for $769, or $899 for a 256GB SSD.

MojoKid writes: Intel just officially launched its first server products built on its advanced 10nm manufacturing process node, the 3rd Gen Xeon Scalable family of processors. 3rd Gen Xeon Scalable processors are based on the 10nm Ice Lake-SP microarchitecture, which incorporates a number of new features and enhancements. Core counts have been significantly increased with this generation, and now offer up to 40 cores / 80 threads per socket versus 28 cores / 56 threads in Intel's previous-gen offerings. The 3rd Gen Intel Xeon Scalable processor platform also supports up to 8 channels of DDR4-3200 memory, up to 6 terabytes of total memory, and up to 64 lanes of PCIe Gen4 connectivity per socket, for more bandwidth, higher capacity, and copious IO.

New AI, security and cryptographic capabilities arrive with the platform as well. Across Cloud, HPC, 5G, IoT, and AI workloads, new 3rd Gen Xeon Scalable processors are claimed to offer significant uplifts across the board versus their previous-gen counterparts. And versus rival AMD's EPYC platform, Intel is also claiming many victories, specifically when AVX-512, new crypto instructions, or DL Boost are added to the equation. Core counts in the line-up range from 8 — 40 cores per processor and TDPs vary depending on the maximum base and boost frequencies and core count / configuration (up to a 270W TDP). Intel is currently shipping 3rd Gen Xeon Scalable CPUs to key customers now, with over 200K chips in Q1 this year and a steady ramp-up to follow.

"AMD and Intel have both proposed better ways of doing interrupt and exception handling the last few months," reports LinuxReviews.org.

Then they share this analysis Linus Torvalds posted on the Real World Technologies forum: "The AMD version is essentially "Fix known bugs in the exception handling definition".

The Intel version is basically "Yeah, the protected mode 80286 exception handling was bad, then 386 made it odder with the 32-bit extensions, and then syscall/sysenter made everything worse, and then the x86-64 extensions introduced even more problems. So let's add a mode bit where all the crap goes away".

In contrast, the AMD one is basically a minimal effort to fix actual fundamental problems with all that legacy-induced crap that are nasty to work around and that have caused issues...

Both are valid on their own, and they are actually fairly independent. Honestly, the AMD paper looks like a quick "we haven't even finished thinking all the details through, but we know these parts were broken, so we might as well release this".

I don't know how long it has been brewing, but judging by the "TBD" things in that paper, I think it's a "early rough draft"."
In the article (shared by long-time Slashdot reader xiando), LinuxReviews.org summarizes the state of the conversation today: Torvalds went on to say that while AMD's proposed "quick fix" would be easier to implement for him and others operating system vendors, it's not ideal in the long run. Intel's proposal throws the entire existing interrupt descriptor table (IDT) delivery system under the bus so it can be replaced with what they call a new "FRED event delivery" system. Torvalds believes this is a better long-term solution...

While the pros and cons of Intel and AMD's respective proposals for interrupt and event handling in future processors are worthy of discussion, it's in reality mostly up to Intel. They are the bigger and more powerful corporation. It is more likely than not that future processors from Intel will use their proposed Flexible Return and Event Delivery system. Their next generation processors won't, it will take years not months before consumer CPUs have the FRED technology. Remember, the above-mentioned technical document was published earlier this month [in March]. Things do not magically go from the drawing-board to store-shelves overnight.

Intel isn't going to just hand the FRED technology over to AMD and help them implement it. We will likely see both move forward with their own proposals. Intel will have FRED and AMD will have Supervisor Entry Extensions until AMD, inevitably, adopts FRED or some form of it years down the line.
They also note that Torvalds took issue with a poster arguing that microkernels are more secure than monolithic kernels like Linux. "Bah, you're just parroting the usual party line that had absolutely no basis in reality and when you look into the details, doesn't actually hold up.

It's all theory and handwaving and just repeating the same old FUD that was never actually really relevant."

US chipmaker AMD advised customers last week to disable a new performance feature if they plan to use CPUs for sensitive operations, as this feature is vulnerable to Spectre-like side-channel attacks. From a report: Called Predictive Store Forwarding (PSF), this feature was added to AMD CPUs part of the company's Zen 3 core architecture, a processor series dedicated to gaming and high-performance computing, which launched in November 2020. The feature implements a technique called speculative execution, which works by running multiple alternative CPU operations in advance to make results available faster, and then discarding "predicted" data once deemed unneeded.

ArsTechnica: Today marks the start of retail availability for Intel's 2021 gaming CPU lineup, codenamed Rocket Lake-S. Rocket Lake-S is still stuck on Intel's venerable 14 nm process -- we've long since lost count of how many pluses to tack onto the end -- with features backported from newer 10 nm designs. Clock speed on Rocket Lake-S remains high, but thread counts have decreased on the high end. Overall, most benchmarks show Rocket Lake-S underperforming last year's Comet Lake -- let alone its real competition, coming from AMD Ryzen CPUs. Our hands-on test results did not seem to match up with Intel's marketing claims of up to 19 percent gen-on-gen IPC (Instructions Per Clock cycle) improvement over its 10th-generation parts. It shouldn't come as an enormous surprise that Core i9-11900K underperforms last year's Core i9-10900K in many multithreaded tests -- this year's model only offers eight cores to last year's 10. On the plus side, Intel's claims of 19% gen-on-gen IPC are largely borne out here, mostly balancing the loss out in Passmark and Geekbench. This year's Core i5 makes a much better showing than its Core i9 big sibling. In Cinebench R20, Core i5-11600K almost catches up with Ryzen 5 5600X, and it easily dominates last year's Comet Lake i5 equivalent. It doesn't catch up to its Ryzen competitor in Passmark or Geekbench multithreaded tests, but it outpaces last year's model all the way around.

MojoKid writes: AMD just unveiled its latest RDNA 2-based GPU that targets 1440p PC gamers, known as Radeon RX 6700 XT. The Radeon RX 6700 XT is built around the company's Navi 22 GPU. In terms of core counts, Navi 22 is effectively a Navi 21 -- the "Big Navi" GPU used on the powerful Radeon RX 6900 XT -- lopped in half. AMD's Radeon RX 6700 XT has fewer CUs and Ray Accelerators (40 vs. 80), and 50% of the total number of Stream Processors (2,560 vs. 5,120). Other parts of the of Navi 22, however, aren't scaled back quite as far. For example, the Radeon RX 6700 XT has 96MB of Infinity Cache, down from 128MB of on the 6900 XT. And the 6700 XT's memory interface is 192-bits wide versus 256-bits on Radeon RX 6800 / 6900 series cards. The 6700 XT also features 12GB of GDDR6 memory (versus 16GB).

AMD has set the MSRP for its Radeon RX 6700 XT at $479. That puts its price higher than the competing GeForce RTX 3060 Ti ($399 MSRP), but somewhat lower than the RTX 3070 ($499 MSRP). Looking at the numbers, that's right where the Radeon RX 6700 XT falls in terms of performance with traditional rasterization. Factor ray tracing into the mix, however, and the Radeon falls behind both of NVIDIA's competitive products. Radeon RX 6700 XT card should be available starting today but for sure demand will be very high, so supply will likely be limited.

The new generation of Intel Core CPUs is here. Intel is using a new architecture on its ancient 14nm process to power the 11th-generation Rocket Lake-S processors. From a report: That results in some significant power improvements, but it also means that Intel can only fit 8 cores on its flagship Core i9-11900K. That sacrifice to the number of cores looks bad compared to the 12-core AMD Ryzen 9 5900X or even the last-gen 10-core i9-10900K. But Intel is also promising massive improvements to efficiency that should keep the Rocket Lake-S parts competitive -- especially in gaming. Rocket Lake-S CPUs launch March 30. The $539 Core i9-11900K has 8 cores and 16 threads with a single-core Thermal Velocity boost of 5.3GHz and 4.8GHz all-core boost. The slightly more affordable $399 i7-11700K boosts up to 5GHz, and the i5-11600K is $262 with 6 cores at a 4.9GHz boost.

While the lack of cores is going to hurt Rocket Lake-S CPUs in multi-threaded applications, Intel claims that its 19% improvement to instructions per clock (IPC) will make up much of the difference. The UHD graphics processor in the CPUs also deliver 50% better performance than last generation. Of course, Intel is focusing on games because that is where its processors remain the most competitive versus AMD. And that should continue with its Rocket Lake-S chips. These high-clocked parts with improved performance should keep up and even exceed AMD's Zen 3 chips in certain games, like Microsoft's Flight Simulator (according to Intel).

MojoKid writes: AMD announced new additions to its EPYC server processor lineup today, codenamed Milan. The company's EPYC 7003 series brings with it significantly improved IPC and per-core performance, better multi-core scaling, and more flexible memory configuration options, in a package that's socket compatible with its previous-gen CPUs. Like the current AMD Ryzen 5000 series desktop processors, new EPYC 7003 CPUs leverage AMD's new Zen 3 microarchitecture. Unlike its desktop parts, however, EPYC 7003 server processors use much larger packaging and feature up to CPU nine chiplets (up to eight 7nm CPU dies and a 12nm IO die), with up to 64 physical cores and 128 threads per socket. As things stand today, Intel doesn't currently have any Xeon processors that can match AMD in terms of single-socket core density. As such, AMD's EPYC 7003 series should consistently offer better performance in many workloads. Pricing for these new big iron processors ranges from $913 or the 16-core 7313P, and up to $7,890 for the powerful EPYC 7763, which AMD is calling "the world's highest-performing server processor." Though nearly $8K is not cheap, AMD appears to be continuing its aggressive price strategy with the EPYC 7003 series, relative to Intel's Xeon Scalable processors. The company also announced a who's who of data center and cloud service OEMs supporting the new platform, including AWS, Azure, Dell Technologies, HPE, Cisco, Google Cloud, Oracle and others.

MojoKid writes: AMD announced a new member of its Radeon RX 6000 series graphics card line-up today, dubbed Radeon RX 6700 XT. Based on AMD's RDNA 2 GPU architecture, the Radeon RX 6700 XT targets high frame rate 1440p gaming at max image quality with an MSRP of $479. The new GPU has 40 Compute Units (CUs) with 40 Ray Tracing Accelerators, 96MB of on-chip Infinity Cache, and 12Gb of GDDR6 memory. Game Clocks of up to 2424MHz will be possible and board power is rated for 230 watts. Versus NVIDIA's current competitive offerings, AMD is claiming wins for the Radeon RX 6700 XT across many titles at 1440p/max settings versus the GeForce RTX 3060 Ti and RTX 3070, but with the added benefit of a larger 12GB frame buffer, which should add a measure of future-proofing as games get more graphically complex. Finally, AMD also revealed that it will be doing something a bit different with the launch of the Radeon RX 6700 XT. AMD-built reference cards will be available directly from AMD.com and numerous partner boards will be available from retailers and system builders, all on March 18th.

Nvidia has shared its Q4 2021 earnings, and despite the company's GPUs being in extremely low supply, it didn't seem to hurt how much money the company made. From a report: In fact, it reported a record $5 billion in revenue, which is up 61 percent year-over-year. What's more impressive is that Nvidia expects to make another $5 billion in revenue during Q1 2022. This positive outlook is surprising given that Q1 is generally slower than other quarters, even for the biggest tech companies, as it follows the rush of people buying lots of products during the holiday period. It's generally a slower period in general for product releases across tech and gaming. Also, let's not forget the GPU shortage is still happening. Nvidia reiterated that sparse supply will continue through the next quarter, but that's likely factored into its rosy revenue prediction.

Nvidia says it expects most of that $5 billion revenue estimate in Q1 2022 to come from the gaming market, despite being the segment it's currently having the toughest time serving. Since the launch of the RTX 30-series desktop graphics cards, leading with the RTX 3080, 3090, 3070, and followed by other products, Nvidia hasn't been able to meet the demand -- though it's not the only company affected. AMD has also struggled, perhaps more than Nvidia, to keep a steady stock of graphics cards heading to retailers.

According to Phoronix, AMD currently has several interesting job openings on the Linux front. From the report: While AMD has been delivering reliable Linux support with their recent launches, there is room for improvement in areas like more timely compiler support for new processors, better alignment of their new hardware enablement for getting the code not only upstreamed but into distributions for launch-day, and similar areas. Based on recent job postings, it looks like AMD is working to make such strides.

Here is a look at some of the new and currently active Linux-related job openings at AMD: [Manager Linux Kernel Development, Linux Technical Lead, Linux Engineer, and Linux Systems Architect, among other traditional software/hardware engineering roles].

Several of these new job descriptions do begin with, "step up into a new organization built to engage more strategically and deeply with the technical teams of our commercial customers." Interestingly, I only see that opening line on their current Linux job postings. When asking AMD if there is a "new (Linux) organization" at AMD, the comment was there is no organization to announce but this is part of the overall expansion at AMD. So for now it's back to dreaming about a new unit akin to the defunct AMD Operating System Research Center that previously drove their Linux support or Intel's former Open-Source Technology Center.

If you're one of the few people still using a PC with an x86 processor more than 15 years old, here's another reason to upgrade: the devices will not work with future Chrome releases, starting with version 89 of the world's most popular browser. TechSpot reports: The Chromium development team announced that CPUs older than the Intel Core 2 Duo and AMD Athlon 64 would not work with Chrome 89 and future versions as they do not meet the new minimum instruction set requirement of SSE3 (Supplemental Streaming SIMD Extensions 3) support. So, if you are still sporting an Intel Atom or Celeron M CPU, you'll soon be counting Chrome as one of the many programs that are incompatible with your potato-like rig. The devices will no longer attempt to install the browser, while running it will result in the software crashing. It's noted that the change only affects Windows as Chrome OS, Android and, Mac already require SSE3 support.

Tesla has unveiled refreshed versions of its Model X and Model S cars, revealing that both are equipped with gaming hardware supporting "up to 10 teraflops of processing power." This theoretically puts a car within the ballpark of a new generation console. From a report: The Tesla models, priced in excess of $80,000 and shipping in March, are fitted with hardware to power Tesla Arcade, an in-car gaming system that is already available in current Tesla models. The difference is that previous models are only able to run less demanding games such as Cuphead and Cat Quest, while the promotional materials for the new Tesla models show The Witcher 3 displayed on the 17" central console. This suggests a significant step up for the car's gaming potential. Specifics on how powerful the car's gaming rig is isn't easy to tell, as the quoted "up to 10 teraflops of processing power" can't be directly translated to the power of a PS5, which is capable of 10.28 teraflops. The accompanying components must also be taken into account, and Tesla has offered no details on the full specs of the hardware. It's unclear if Nvidia or AMD GPUs are being used, or if it all comes from Tesla's own system-on-a-chip. And while The Witcher 3 is an impressive game by... err... car standards, it's very much a last-gen experience now. Theoretically, though, the system in the new Teslas is capable of strong gaming performance.

Ryan Smith, writing at AnandTech: Following plans first unveiled last year during the launch of their DG1 GPU, Intel sends word this morning that the first Iris Xe video cards have finally begun shipping to OEMs. Based on the DG1 discrete GPU that's already being used in Intel's Iris Xe MAX laptop accelerators, the Iris Xe family of video cards are their desktop counterpart, implementing the GPU on a traditional video card. Overall, with specifications almost identical to Xe MAX, Intel is similarly positioning these cards for the entry-level market, where they are being released as an OEM-only part. As a quick refresher, the DG1 GPU is based on the same Xe-LP graphics architecture as Tiger Lake's integrated GPU. In fact, in broad terms the DG1 can be thought of as a nearly 1-to-1 discrete version of that iGPU, containing the same 96 EUs and 128-bit LPDDR4X memory interface as Tiger Lake itself. Consequently, while DG1 is a big first step for Intel -- marking the launch of their first discrete GPU of the modern era -- the company is planning very modestly for this generation of parts. The first DG1 GPUs were shipped in the fall as part of Intel's Iris Xe MAX graphics solution for laptops. At the time, Intel also indicated that a desktop card for OEMs would also be coming in 2021, and now, right on schedule, those desktop cards have begun shipping out.

Intel's new CEO, Pat Gelsinger, doesn't start his new role until February, but he's already prepping the company to take on Apple's M1 chips. From a report: The Oregonian, a local newspaper in Oregon where Intel maintains a large presence, reports that the chip maker held an all-hands company meeting yesterday, and Gelsinger attended. "We have to deliver better products to the PC ecosystem than any possible thing that a lifestyle company in Cupertino" makes, Gelsinger reportedly told Intel employees. "We have to be that good, in the future." Intel has been facing increased competition from both Apple and AMD recently. Apple announced its transition to its own silicon back in June, calling it a "historic day for the Mac." The transition has gone well, with M1-based Macs providing impressive performance and battery life compared to existing Intel-based Macs.

Today, Qualcomm has announced they will be acquiring NUVIA for $1.4 billion -- acquiring the start-up company consisting of industry veterans which originally were behind the creation of Apple's high-performance CPU cores. AnandTech reports: NUVIA was originally founded in February 2019 and coming out of stealth-mode in November of that year. The start-up was founded by industry veterans Gerard Williams III, John Bruno and Manu Gulati, having extensive industry experience at Google, Apple, Arm, Broadcom and AMD. Gerard Williams III in particular was the chief architect for over a decade at Apple, having been the lead architect on all of Apple's CPU designs up to the Lightning core in the A13 -- with the newer Apple A14 and Apple M1 Firestorm cores possibly also having been in the pipeline under his direction.

NUVIA had been able to recruit a lot of top industry talent from various CPU design teams across the industry, and had planned to enter the high-performance computing and enterprise market with a new server SoC with a new CPU core dubbed "Phoenix." NUVIA particularly had made aggressive claims about how their design would be able to significantly outperform the competition both in raw performance and power efficiency once it came to market -- usually such claims are always to be taken with scepticism, however due to the members of the design team and talent having proven themselves in the form of Apple's very successful CPU microarchitectures, there's a lot more weight and credibility to them compared to other start-ups.

Qualcomm now acquiring NUVIA gives them the possibility to take advantage of the start-up's early work in the server space, possibly reinvigorating the company's ambitions in the server space, and giving them a second shot at the market. It's to be noted however that in today's press release about the acquisition there had been no mention of server or enterprise plans. Furthermore, the move also has larger repercussions in the consumer space, with Qualcomm claiming that NUVIA CPU designs are expected to be deployed in flagship mobile SoCs and next generation laptops, as well as other industrial applications such as digital cockpits and ADAS.

Intel CEO Bob Swan is set to step down effective Feb. 15. From a report: VMWare CEO Pat Gelsinger will take over the position, sources told CNBC. Intel's stock was up about 13% in premarket trading following the news. VMWare's stock was down nearly 5%. Swan was named CEO in January 2019 after serving as interim CEO for seven months. During Swan's tenure, Intel has suffered blows from competitors. Over the summer, Intel reported that its latest generation chips would be delayed while AMD's were already shipping inside laptops. Apple announced in the fall that it would use its own proprietary chips in its Mac computers, breaking a 15-year partnership with Intel for its chip supplies.

Advanced Micro Devices showed off some impressive Ryzen 5000 mobile processors today and teased the performance of its 3rd Gen Epyc server chips. From a report: Those chips are aimed at keeping AMD's performance lead over its rival Intel in the mobile and server markets. AMD CEO Lisa Su showed off the new chips in a keynote speech at CES 2021, the online-only tech trade show. AMD is launching its Ryzen 5000 Series mobile processors for gaming laptops and thin-and-light notebooks. These eight-core x86 chips are built with a 7-nanometer manufacturing process (where the circuits are 7 billionths of a meter apart). They are also based on the Zen3 design for processor cores, which can process instructions 19% faster per clock cycle than Zen2 cores.

The H-Series focuses on top performance in laptops for gamers and content creators, while the U-Series focuses on thin-and-light notebooks with great battery life. The chips have four to eight cores and they range in power consumption from 15 watts to 45 watts. AMD said the 5000 Series will be available in PCs in February, and we'll see more than 150 systems using it. That compares to 100 systems for the Ryzen 4000 Series and 70 for the Ryzen 3000.
