MojoKid writes: After months of speculation and early look teases, Intel's 12th Gen Core processors are finally ready for prime time. Today marks the embargo lift for independent reviews of Alder Lake and it's clear Chipzilla is back and bringing the fight again versus chief rival AMD. Intel 12th Gen Core processors incorporate two new CPU core designs, dubbed Efficiency (E-core) and Performance (P-core). In addition to this new hybrid core architecture, 12th Gen Core processors and the Z690 motherboard chipset platform also feature support for the latest memory and IO technologies, including PCI Express Gen 5, DDR5, Thunderbolt 4 and Wi-Fi 6E. The new Core i9-12900K features a monolithic, 16-core (24-thread) die with 8 Performance cores and 8 Efficiency cores, while the Core i5-12600K has 10 cores/16-threads, comprised of 6 P-cores and 4 E-cores. Alder Lake E-cores don't support HyperThreading but P-cores can process two threads simultaneously while E-cores can manage only one, hence the asymmetric core counts.

In the benchmarks, the 16-core Core i9-12900K doesn't sweep AMD's 16-core Ryzen 9 5950X across the board in multi-threaded tests, but it certainly competes very well and notches plenty of victories. In the lightly-threaded tests though, it's a much clearer win for Intel and gaming is an obvious strong point as well. Alder Lake's performance cores are as fast as they come. The $589 (MSRP) 16-core Core i9-12900K competes well with the $750 16-core Ryzen 9 5950X, and the $289 10-core Core i5-12600K has a lower MSRP than a $299 6-core Ryzen 5 5600X. The new Core i5's power and performance look great too, especially when you consider this $289 chip outruns Intel's previous-gen flagship Core i9-11900K more often than not, and it smokes a Ryzen 5 5600X.

NotebookCheck: It seems that Intel was not telling the full story when it compared the Core i9-12900K against the Ryzen 9 5950X, currently AMD's most comparable processor. As it turns out, Intel allowed the Core i9-12900K to consume 2.4x the power of its AMD competitor and benchmarked the Ryzen 9 5950X using an older version of Windows 11 with AMD performance issues.

Phoronix: Now that Windows 11 has been out as stable and the initial round of updates coming out, I've been running fresh Windows 11 vs. Linux benchmarks for seeing how Microsoft's latest operating system release compares to the fresh batch of Linux distributions. First up is the fresh look at the Windows 11 vs. Linux performance on an Intel Core i9 11900K Rocket Lake system. Microsoft Windows 11 Pro with all stable updates as of 18 October was used for this round of benchmarking on Intel Rocket Lake. The Windows 11 performance was being compared to all of the latest prominent Linux distributions, including: Ubuntu 20.04.3 LTS, Ubuntu 21.10, Arch Linux (latest rolling), Fedora Workstation 35, Clear Linux 35150. All the testing was done on the same Intel Core i9 11900K test system at stock speeds (any frequency differences reported in the system table come down to how the information is exposed by the OS, i.e. base or turbo reporting) with 2 x 16GB DDR4-3200 memory, 2TB Corsair Force MP600 NVMe solid-state drive, and an AMD Radeon VII graphics card.

Each operating system was cleanly installed and then run at its OS default settings for seeing how the out-of-the-box OS performance compares for these five Linux distributions to Microsoft Windows 11 Pro. But for the TLDR version... Out of 44 tests run across all six operating systems, Windows 11 had just three wins on this Core i9 11900K system. Meanwhile Intel's own Clear Linux platform easily dominated with coming in first place 75% of the time followed by Fedora Workstation 35 in second place with first place finishes 9% of the time. The geometric mean for all 44 tests showed Linux clearly in front of Windows 11 for this current-generation Intel platform. Ubuntu / Arch / Fedora were about 11% faster overall than Windows 11 Pro on this system. Meanwhile, Clear Linux was about 18% faster than Windows 11 and enjoyed about 5% better performance overall than the other Linux distributions.

An anonymous reader quotes a report from ZDNet: The reign of Apple's M1 SoC at the top of the Geekbench speed benchmarks may soon be over with the impending arrival of Intel's 12th-generation Alder Lake mobile processors. Hardware site Wccftech appears to have been leaked Intel's upcoming Core i9-12900HK mobile CPU, and has now revealed the first benchmarks. The results show Intel's mobile CPU narrowly outperforming Apple's flagship 10-core M1 Max, which also integrates a 32-core GPU and 64GB of unified memory.

In these latest tests, the Core i9-12900HK outperforms the M1 Max on both single-core and multi-core benchmarks. The margin is slim, but is important for Intel since Apple ditched its CPUs for its own designs in new MacBooks. Intel's Alder Lake CPU didn't beat the M1 Max by much, with respective single-core scores of 1851 and 1785. It beat the Core i9-11980HK and AMD's top mobile CPU, the Ryzen 5980HX, by a bigger margin: the latter two CPUs saw scores of 1616 and 1506, respectively. In the multi-core benchmark, the Core i9-12900HK scored 13256 versus the M1 Max's score of 12753. Again, it trounced AMD's 5980HX, which scored 8217. Wccftech's Alder Lake benchmarks were run using Windows 11, so it's possible Thread Director's hardware scheduling influenced the results.

AMD and Microsoft have issued patches to address the slowdowns reported with Ryzen processors when Windows 11 launched. Engadget reports: The latest chipset driver (version 3.10.08.506) should take care of the UEFI CPPC2 issue, which in some cases didn't "preferentially schedule threads on a processor's fastest core," AMD said. That could have slowed down apps that are sensitive to CPU thread performance. AMD noted that the problem was likely more noticeable in more powerful processors with more than eight cores and 65W or higher Thermal Design Power (TDP).

Meanwhile, Microsoft is rolling out a software update tackling a bug that increased L3 cache latency. The issue impacted apps that need quick memory access, which in turn caused CPUs to slow down by up to 15 percent. The patch, Windows 11 update KB5006746, will be available starting today, but at the time of writing, a page containing instructions for installing it isn't yet live. You should be able to install it via Windows Update too.

The original Xbox was released 20 years ago next month, and to mark the upcoming anniversary, the console's designer has apologized to AMD's engineers and its CEO for Microsoft's last-minute decision to drop AMD for rival Intel. GameSpot reports: Seamus Blackley apologized on Twitter to the AMD engineers who worked with Microsoft to create the prototype Xbox consoles that the company used in the lead-up to the OG Xbox's release in November 2001. To AMD CEO Lisa Su, Blackley said, "I beg mercy." "I was standing there on the stage for the announcement, with [Bill Gates], and there they were right there, front row, looking so sad," he said of AMD engineers in the room. "I'll never forget it. They had helped so much with the prototypes. Prototypes that were literally running the launch announcement demos ON AMD HARDWARE." "I felt like such an ass," Blackley said. Microsoft dropped AMD in favor of Intel due to "pure politics," Blackley said in another tweet.

AMD warned last week that its chips are experiencing performance issues in Windows 11, and now Microsoft's first update to its new OS has reportedly made the problems worse. From a report: TechPowerUp reports that it's seeing much higher latency, which means worse performance, after the Windows 11 update went live yesterday. AMD and Microsoft found two issues with Windows 11 on Ryzen processors. Windows 11 can cause L3 cache latency to triple, slowing performance by up to 15 percent in certain games. The second issue affects AMD's preferred core technology, that shifts threads over to the fastest core on a processor. AMD says this second bug could impact performance on CPU-reliant tasks. TechPowerUp measured the L3 cache latency on its Ryzen 7 2700X at around 10ns, and Windows 11 increased this to 17ns. "This was made much worse with the October 12 'Patch Tuesday' update, driving up the latency to 31.9ns," says TechPowerUp. That's a huge jump, and the exact type of issue AMD warned about.

AMD said Windows 11 can cut game performance on Ryzen CPUs by 10 to 15 percent, and the operating system may not utilize AMD's "preferred core" technology, but a fix is in the works. PCWorld reports: A support note on AMD's web site published this week said Windows 11 may increase L3 cache latency a whopping threefold, which can cause slowdowns in latency sensitive applications. Lighter duty, cache-sensitive games might see a 3 percent to 5 percent hit, and lighter-duty games as e-sports titles could see frame rates drop from 10 to 15 percent. AMD also said its "preferred core" feature, which tells the operating system which core in each CPU can hit the highest clock, also doesn't work right in Windows 11. Each CPU is tested to see which core will run the fastest at the factory and is marked so the OS will dispatch tasks to that "preferred core." Since Windows 11 doesn't seem to work with it right now, any performance bump from using the best core wouldn't happen. The company said the performance cost would be most noticeable in CPUs with more than 8 cores and with TDP ratings above 65 watts.

An anonymous reader quotes a report from The Register: The European Processor Initiative (EPI) has run the successful first test of its RISC-V-based European Processor Accelerator (EPAC), touting it as the initial step towards homegrown supercomputing hardware. EPI, launched back in 2018, aims to increase the independence of Europe's supercomputing industry from foreign technology companies. At its heart is the adoption of the free and open-source RISC-V instruction set architecture for the development and production of high-performance chips within Europe's borders. The project's latest milestone is the delivery of 143 samples of EPAC chips, accelerators designed for high-performance computing applications and built around the free and open-source RISC-V instruction set architecture. Designed to prove the processor's design, the 22nm test chips -- fabbed at GlobalFoundries, the not-terribly-European semiconductor manufacturer spun out of AMD back in 2009 -- have passed initial testing, running a bare-metal "hello, world" program as proof of life.

It's a rapid turnaround. The EPAC design was proven on FPGA in March and the project announced silicon tape-out for the test chips in June -- hitting a 26.97mm2 area with 14 million placeable instances, equivalent to 93 million gates, including 991 memory instances. While the FPGA variant, which implemented a subset of the functions of the full EPAC design, was shown booting a Linux operating system, the physical test chips have so far only been tested with basic bare-metal workloads -- leaving plenty of work to be done. Earlier today, the UK government released its 10-year plan to make the country a global "artificial intelligence superpower," seeking to rival the likes of the U.S. and China. "The so-called 'National Artificial Intelligence Strategy' is designed to boost the use of AI among the nation's businesses, attract international investment into British AI companies and develop the next generation of homegrown tech talent," reports CNBC.

AMD's CFO Devinder Kumar has commented that AMD stands ready to manufacture Arm chips if needed, noting that the company's customers want to work with AMD on Arm-based solutions. From a report: Kumar's remarks came during last week's Deutsche Bank Technology Conference, building on comments from AMD CEO Lisa Su earlier in the year that underscored the company's willingness to create custom silicon solutions for its customers, be they based on x86 or Arm architectures. Intel also intends to produce Arm and RISC-V chips, too, meaning that the rise of non-x86 architectures will be partially fueled by the stewards of the dominant x86 ecosystem. "But I'll tell you from my standpoint, when you look at compute solutions, whether it's x86 or ARM or even other areas, that is an area for our focus on investment for us," AMD CFO Devinder Kumar responded to a question about the company's view of competing Arm chips. "We know compute really well. Even ARM, as you referenced, we have a very good relationship with ARM. And we understand that our customers want to work with us with that particular product to deliver the solutions. We stand ready to go ahead and do that even though it's not x86, although we believe x86 is a dominant strength in that area."

An anonymous reader quotes a report from PCWorld: The latest version of Radeon Software adds an unusual (and welcome) new twist: The ability to automatically overclock your Ryzen processor if you're rocking an all-AMD gaming desktop. Yes, your GPU software can speed up your CPU now, too -- and it can do it all with a single click. [...] The addition of Ryzen auto-overclocking in Radeon Software 21.9.1 continues the theme, and might just allow you to ditch AMD's separate Ryzen Master tool if you're running a Team Red graphics card. They'll need to be newer hardware, though, as the feature currently only supports AMD's latest Ryzen 5000 CPUs and Radeon RX 6000 GPUs.

AMD's blog describes how to use the new tool: "To access this easy-to-use feature, open up Radeon Software using the hotkey 'ALT' + 'R', navigate to the 'Performance' tab found at the top of the window, and select 'Tuning' in the sub tab directly below it. If you have the latest generation of AMD Ryzen and Radeon product installed on your system, a 'Tuning Control' section should appear for your system, allowing you to select 'Auto Overclock' to increase performance on both your processor and graphics card. We also have a new tuning section for CPUs, allowing you to overclock just your CPU. When the feature is selected, the system will ask for a restart and once you are back in Windows, you will be good to go!" "Radeon Software 21.9.1 also adds official Windows 11 support and the ability for Radeon RX 5000-series GPUs to tap into Smart Access Memory," adds PCWorld. "AMD also took the time to tout FidelityFX Super Resolution's rapid uptake. The DLSS rival is now supported in 27 games, with Arkane's awesome-looking Deathloop set to launch this week with native FSR support in place."

Intel has pivoted on its server strategy in order to fight a supply-constrained AMD, reports DigiTimes. It's reportedly flooding the market with chips at discount pricing, rather than sticking to MSRP. From a report: While some reports point toward a relative normalization on AMD's CPU supply, AMD has two distinct disadvantages when compared to Intel: It has fewer revenue sources than its much bigger CPU rival, and AMD doesn't own the factories that produce its market-turning Zen chips. Intel, on the other hand, can leverage its vertical integration (meaning that development and manufacturing takes place in an almost entirely Intel-owned and managed supply chain), as well as its massive revenue advantage, to play with final client pricing. In other words, Intel pull a lot more levers to increase demand and (Intel hopes) attract would-be AMD clients back into the Intel fold.

AMD has seemingly been making strides in server market penetration. As seen in renowned system distributor Puget Systems' statistics, AMD has risen from a 5% share in systems sold since June 2020, up to a dominating 60% as of June 2021. However, unserved demand means that companies looking to invest in their server infrastructure or who aim to deploy AMD chips in any major way sometimes can't wait for the chips to become available. And Intel is smartly making it more attractive for those companies to go back to the Intel fold, or to skip AMD in the first place.

PCGamer reports: Microsoft continues to double down on its assertion that the Windows 11 system requirements are absolutely necessary, and this whole TPM 2.0 schtick is vital for the safety of you, your PC, and maybe even the world. Okay, I made that last bit up, but the big M is sticking to its guns and has released another video backing its decision on excluding a whole lot of hardware that was fine with Windows 10. The latest claim is that you're going to see fewer blue screens of death -- or maybe black screens of death -- because of the new system requirements, citing a "99.8% crash-free experience in the [Windows 11] preview." Look, there's still a part of us that feels at some point in the future, maybe the distant future, Microsoft will turn around and say 'You know, what? We don't mind what processor you use with Windows 11,' but for right now this is where we're at. You need a modern CPU for Windows 11 for security and reliability.

And maybe a little performance. "So the requirement for Intel 8th Gen and AMD Ryzen 2000-series, and newer, chipsets does definitely contribute to performance," states Microsoft VP Steve Dispensa in the recent video. "But the main rationale here is actually the balanced security with performance. Security is at the core of these requirements." He does point to differences in how Windows 11 prioritises apps running in the foreground window. With the system running at 90% CPU load, it's still possible to get a responsive experience opening and using foreground apps thanks to these prioritisations.

Lenovo will ring in the arrival of Windows 11 with a pair of premium AMD Ryzen-based laptops. PCWorld reports: The IdeaPad Slim 7 Carbon will feature a carbon lid and aluminum body to go with its drop-dead gorgeous 14-inch OLED screen. Besides the infinite contrast an OLED provides, Lenovo will use a fast 90Hz, 2880x1800 panel with an aspect ratio of 16:10 on the Slim 7 Carbon. That's just over 5 megapixels with a density of 243 pixels-per-inch. This is one smoking screen. But this beauty goes deeper than the skin. Inside the Slim 7 Carbon, you'll find an 8-core Ryzen 7 5800U with an optional Nvidia GeForce MX450 GPU. Lenovo will offer up to 16GB of power efficient LPDDR4X RAM and up to a 1TB PCIe SSD.
[...]
If a 14-inch screen laptop with a GeForce MX450 isn't enough for you, Lenovo also unveiled a new IdeaPad Slim 7 Pro. It's aimed at someone who needs a little more oomph. The laptop also features a 16:10 aspect ratio screen, which we consider superior to 16:9 aspect ratio laptops for getting work done. The IPS panel shines at a very bright 500 nits, and it's rated for 100 percent of the sRGB spectrum with an option for a 120Hz refresh rate version. Inside the laptop you'll find an 8-core Ryzen 7 5800H, up to 16GB of DDR4, a 1TB PCIe SSD, and up to a GeForce RTX 3050 Laptop graphics chip. Compared to the Slim 7 Carbon, you should expect the CPU to run faster thanks to the additional thermal headroom of the H-class Ryzen chip. The GeForce RTX 3050 Laptop GPU, meanwhile, is based on Nvidia's newest "Ampere" GPU cores instead of the older "Turing" GPU the GeForce MX450 uses in the Slim 7 Carbon. That upgrade translates to far better gaming performance, hardware ray tracing support, and the inclusion of Nvidia hardware encoding and decoding, which can help you use Adobe Premiere on the road.

Long-time Slashdot reader UnknowingFool writes: Last week IBM announced their next generation mainframe CPU Telum. Manufactured by Samsung's 7nm node, each Telum processor has 8 cores with each core running at a base 5GHz. Two processors are combined in a package similar to AMD's chiplet design. A drawer in each mainframe can hold 4 packages (sockets), and the mainframe can hold 4 drawers for combined 256 cores.

Different from previous generations, there is no dedicated L3 or L4 cache. Instead each core has a 32MB L2 cache that can pool to become a 256MB L3 "virtual" cache on the same processor or 2GB L4 "virtual" cache on the same drawer. Also included to help with AI is a on-die but not on-core inference accelerator running at 6TFLOPS using Intel's AVX-512 to communicate with the cores.

Despite Linux reaching its 30th anniversary, "most outside the tech industry will be unaware that Linux has reached such a milestone," writes ZDNet, "even though the project has had a huge impact on everything from smartphones to cloud computing."

They add that Linus Torvalds "poked fun at that lack of recognition in his usual Sunday release note for a new stable version of the Linux kernel." "So I realize you must all still be busy with all the galas and fancy balls and all the other 30th anniversary events, but at some point you must be getting tired of the constant glitz, the fireworks, and the champagne," Torvalds said. "That ball gown or tailcoat isn't the most comfortable thing, either. The celebrations will go on for a few more weeks yet, but you all may just need a breather from them."

Linux 5.14 includes additional features for Intel's Alder Lake mobile-ready CPUs, extra AMD support and better support for the Raspberry Pi 400 PC. "Because 5.14 is out there, just waiting for you to kick the tires and remind yourself what all the festivities are about," notes Torvalds...

Torvalds is upbeat about Linux's future, predicting decades more work for the kernel's several thousand contributors who help shape the Linux kernel and drivers. "Of course, the poor tireless kernel maintainers won't have time for the festivities, because for them, this just means that the merge window will start tomorrow. We have another 30 years to look forward to, after all. But for the rest of you, take a breather, build a kernel, test it out, and then you can go back to the seemingly endless party that I'm sure you just crawled out of," he wrote.

A team of researchers with AMD have filed a patent application that looks toward a more efficient and reliable quantum computing architecture, thanks to a conventional multi-SIMD (Single Instruction Multiple Data) approach. Tom's Hardware reports: According to the application, AMD is researching a system that aims to use quantum teleportation to increase a quantum system's reliability, while simultaneously reducing the number of qubits necessary for a given calculation. The aim is to both alleviate scaling problems and calculation errors stemming from system instability. The AMD patent, titled "Look Ahead Teleportation for Reliable Computation in Multi-SIMD Quantum Processor," aims to improve quantum stability, scalability, and performance in novel, more efficient ways. It describes a quantum architecture based on quantum processing regions: areas of the chip that hold or can hold qubits, lying in wait for their turn on the processing pipeline. AMD's approach aims to improve on existing quantum architectures by actually reducing the number of qubits needed to perform complex calculations -- via the science fiction-esque concept of quantum teleportation.

AMD's design aims to teleport qubits across regions, enabling workloads that would theoretically require in-order execution to become capable of being processed in an out-of-order philosophy. As a quick refresher, in-order execution features dependencies between one instruction and the next, meaning that a workload has to be processed sequentially, with later steps dependent on the previous step being fully processed and its result being known before the chip can move ahead with the computation. As you may imagine, there are chip resources (in this case, qubits) that sit idle until it's their time to perform the next calculation step. On the other hand, Out-of-order execution analyzes a given workload, figures out which parts of it are dependent on previous results and which are not, and executes every step of the instruction that doesn't require a previous result, thus improving performance via increased parallelism.

AMD's patent also includes a look-ahead processor embedded into the architecture, tasked to analyze the input workload, predict what steps can be tackled in parallel (and those that can't), and appropriately distribute the workload across qubits, using a quantum teleporting technique to deliver them to the required quantum processing, SIMD-based region. How this quantum teleportation occurs isn't described in the patent -- it looks like AMD is playing its cards close to its chest on this one.

Internet-grooming company Cloudflare has revealed that it was unable to put Intel inside its new home-brew servers, because they just used too much energy. A Tuesday post by platform operations engineer Chris Howells reveals that Cloudflare has been working on designs for an eleventh-generation server since mid-2020. jaa101 writes: "We evaluated Intel's latest generation of 'Ice Lake' Xeon processors," Howells wrote. "Although Intel's chips were able to compete with AMD in terms of raw performance, the power consumption was several hundred watts higher per server -- that's enormous." Fatally enormous -- Cloudflare's evaluation saw it adopt AMD's 64-core Epyc 7713 for the servers it deploys to over 200 edge locations around the world. Power savings also influenced a decision to go from three disks to two in the new design. A pair of 1.92TB Samsung drives replaced the three of the Korean giant's 960GB units found in previous designs. The net gain was a terabyte of capacity, and six fewer watts of power consumption. Howellls's post also reveals that testing produced data showing that equipping its servers with 512GB of RAM did not produce enough of a performance boost to justify the expense. The company has therefore settled on 384GB of memory, but did jump from DDR4-2933 to DDR4-3200 as the slight cost increase delivered a justifiable performance boost.

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.

MojoKid writes: AMD officially unveiled the Radeon RX 6600 XT in late July but the cards have officially launched today, aimed at 1080p gaming. In a review at HotHardware, PowerColor is offering both a high-end Radeon RX 6600 XT Red Devil and its somewhat more mainstream "Fighter" branded counterpart, for example. Whereas AMD's reference Radeon RX 6600 XT offers a Game clock up to 2359MHz and a Boost clock of 25895MHz, the PowerColor Red Devil peaks at 2428MHz (Game) and 2607MHz (Boost). Those higher GPU clocks result in higher compute performance and fillrate, etc., but the memory configuration and frequency are the same -- so in memory bandwidth constrained situations, performance won't be all that much different.

Performance-wise, with most game titles that use traditional rasterization, the Radeon RX 6600 XT is clearly faster than the GeForce RTX 3060 and previous-gen cards like the Radeon RX 5700 XT or GeForce RTX 2060 Super. However, when you factor ray tracing into the equation, NVIDIA has a distinct and significant advantage still. The Radeon RX 6600 XT Fighter should sell for at or close to its $379 MSRP. PowerColor says that they should be readily available for gamers to purchase today.
