Many companies, including Intel and AMD, have stopped product shipments to Russia amidst the war in Ukraine in the past few months. This has left the Russian state without any new processors from the two prominent x86 designers, thus slowing down the country's technological progress. To overcome this issue, it seems like the solution is embedded in the Chinese Zhaoxin x86 CPUs. According to the latest report from Habr, a motherboard designer called Dannie is embedding Chinese Zhaoxin x86 CPUs into motherboards to provide the motherland with an x86-capable processor. More precisely, the company had designed a BX-Z60A micro-ATX motherboard that embeds Zhaoxin's KaiXian KX-6640MA SoC with eight cores based on LuJiaZui microarchitecture. The SoC is clocked at a frequency range of 2.1-2.7 GHz, carries 4 MB of L2 cache, 16 lanes of PCIe 3.0, and has integrated graphics, all in a 25 Watt TDP.

As far as the motherboard is concerned, it supports two DDR4 memory slots, two PCIe x16 connectors, M.2-2280 and M.2-2230 slots, and three SATA III connectors for storage. For I/O you have USB ports, DisplayPort, HDMI, VGA/D-Sub, GbE, 3.5-mm audio, and additional PS/2 ports. This is a pretty decent selection; however, we don't know the pricing structure. A motherboard with KaiXian KX-6640MA SoC like this is certainly not cheap, so we are left to wonder if this will help Russian users deal with the newly imposed restriction on importing US tech.

AMD and the Mercedes-AMG Petronas Formula One (F1) Team today showcased how AMD EPYC processors improved aerodynamics testing capacity, contributing to the Mercedes-AMG Petronas team winning its eighth Constructors' Championship in the 2021 racing season. By using AMD EPYC processors, the team was able to achieve a 20 percent performance improvement for computational fluid dynamics (CFD) workloads that were used to model and test aerodynamic flow of their F1 car.

"We are proud to partner with the reigning Constructors' Champions, the Mercedes-AMG Petronas Formula One Team, operating at the cutting edge of racing and technology," said, Dan McNamara, senior vice president and general manager, Server Business Unit, AMD. "For F1 teams, having the most effective computational analysis of aerodynamics can mean the difference between winning and losing a race. With AMD EPYC processors, the Mercedes-AMG F1 team can iterate on vehicle design faster and more efficiently than their previous system."

AMD is slowly preparing to transition its consumer base into a new platform and processor architecture with the launch of Ryzen 7000 series processors codenamed Raphael. Based on the new AM5 LGA socket, these processors will come with up to 16 cores and 32 threads at the top-end configurations. Thanks to the latest round of rumors, we managed to find out just what TDP rating two SKUs will carry. According to a well-known leaker @graymon55, AMD is rating the 12-core SKU with a TDP of 105 Watts. On the other hand, the top-end 16-core 7000 series SKU replacing the current Ryzen 9 5950X will carry a large TDP of 170 Watts.

The 170 Watt TDP configuration will likely require better cooling efforts. AMD will probably advise users to invest in better cooling solutions, such as AIO liquid coolers or giant air coolers.

Designing Artificial Intelligence / Machine Learning hardware accelerators takes effort from hardware engineers in conjunction with scientists working in the AI/ML area itself. A few years ago, we started seeing AI incorporated into parts of electronic design automation (EDA) software tools, helping chip designers speed up the process of creating hardware. What we were "used to" seeing AI do are just a couple of things like placement and routing. And having that automated is a huge deal. However, it looks like the power of AI for chip design is not going to stop there. Researchers at Google and UC Berkeley have made a research project that helps AI design and develop AI-tailored accelerators smaller and faster than anything humans made.

In the published paper, researchers present PRIME - a framework that created AI processors based on a database of blueprints. The PRIME framework feeds off an offline database containing accelerator designs and their corresponding performance metrics (e.g., latency, power, etc.) to design next-generation hardware accelerators. According to Google, PRIME can do so without further hardware simulation and has processors ready for use. As per the paper, PRIME improves performance upon state-of-the-art simulation-driven methods by as much as 1.2x-1.5x. It also reduces the required total simulation time by 93% and 99%, respectively. The framework is also capable of architecting accelerators for unseen applications.

ASRock Industrial launches a new range of industrial motherboards powered by 12th Gen Intel Core Processors (Alder Lake-S) with up to 16 cores and 24 threads, supporting the new Intel 600 Series W680, Q670, and H610 chipsets. Featuring high computing power with performance hybrid architecture and enhanced AI capabilities, rich IOs and expansions for up to quad displays 4K@60 Hz, USB 3.2 Gen2x2 (20 Gbit/s), triple Intel 2.5 GbE LANs with real-time TSN, multi M.2 Key M, ECC memory, plus TPM 2.0, and wide voltage support. The new series covers comprehensive form factors, including industrial Mini-ITX, Micro-ATX, and ATX motherboards for diverse applications, such as factory automation, kiosks, digital signage, smart cities, medical, and Edge AIoT applications.

Intel's Alder Lake processors have two types of cores present, with two distinct sets of features and capabilities enabled. For example, smaller E-cores don't support the execution of AVX-512 instructions, while the bigger P-cores have support for AVX-512 instructions. So Intel has decided to remove support for it altogether not to create software errors and run into issues with executing AVX-512 code on Alder Lake processors. This happened just months before the launch of Alder Lake, making us see some initial motherboard BIOSes come with AVX-512 enabled from the box. Later on, all motherboard makers pulled the plug on it, and it is a rare sight to see support for it.

However, it seems like MSI is unhappy with the lack of AVX-512, and the company is reenabling partial support for it. According to Xaver Amberger, editor at Igor's Lab, MSI reintroduces selecting microcode version with its MEG Z690 Unify-X motherboard. There is an option for AVX-512 enablement in the menu, and it is indeed a functional one. With BIOS A22, MSI enabled AVX-512 instruction execution, and there are benchmarks to prove it works. This shows an advantage of 512-bit wide execution units of AVX-512 over something like AVX2, which offers only 256-bit wide execution units. In applications such as Y-Cruncher, AVX-512 enabled the CPU to reach higher performance targets while consuming less power.

Tachyum today announced that it was selected by the Slovak Republic to participate in the latest submission for the Important Projects of Common European Interest (IPCEI), to develop Prodigy 2 for HPC/AI. Prodigy 2 for HPC/AI will enable 1 AI Zettaflop and more than 10 DP Exaflops computers to support superhuman brain-scale computing by 2024 for under €1B. As part of this selection, Tachyum could receive a 49 million Euro grant to accelerate a second-generation of its Tachyum Prodigy processor for HPC/AI in a 3-nanometer process.

The IPCEI program can make a very important contribution to sustainable economic growth, jobs, competitiveness and resilience for industry and the economy in the European Union. IPCEI will strengthen the EU's open strategic autonomy by enabling breakthrough innovation and infrastructure projects through cross-border cooperation and with positive spill-over effects on the internal market and society as a whole.

AMD's Ryzen 7000 series of desktop processors based on the novel Zen 4 core architecture are scheduled to arrive in the second half of 2022. While we are not sure just how big the architectural differences will be going from Zen 3 (with or without 3D V-cache) to the new Zen 4 core, we have some leaked information that confirms the existence of two SKUs that reveal additional details about the processor configuration. In the MilkyWay@Home project, aiming to create a model of the Milky Way galaxy by utilizing countless PCs across the globe, we found two next-generation Ryzen 7000 SKUs. The MilkyWay@Home project isn't a benchmark. However, it is a valuable reference where the next generation processors appeared.

First in line is the 100-000000666-21_N CPU, a codename for an eight-core, sixteen-threaded design. This model should correspond to the AMD Ryzen 7 7800X CPU, a successor to the Ryzen 7 5800X model. Next in line is the 100-000000665-21_N CPU with 16 cores and 32 threads, a successor to the Ryzen 9 5950X named Ryzen 9 7950X. One important thing to note is that these new CPUs feature different level two (L2) cache configurations. With the previous generation 5000 series "Vermeer" processors, the L2 cache was locked at 512 KB per core. However, according to today's leak, the upgraded Zen 4 IP will bring 1024 KB of L2 cache per core, doubling the cache size at one of the fastest levels.

Today at CES 2022, Intel announced the world's fastest mobile processor, bringing its performance hybrid architecture to mobile platforms for the first time with new 12th Gen Intel Core mobile processors that are up to 40 percent faster than the previous generation mobile processor. Intel introduced 28 new 12th Gen Intel Core mobile processors that deliver a feature-rich suite of capabilities to create laptops for people to compute whenever and wherever they need - without compromise.

With the introduction of the full 12th Gen Intel Core desktop processor lineup, the 12th Gen Intel Core processor family also represents the company's most scalable lineup to date, powering designs across consumer, enterprise, the Internet of Things (IoT) and other applications. "Intel's new performance hybrid architecture is helping to accelerate the pace of innovation and the future of compute," said Gregory Bryant, executive vice president and general manager of Intel's Client Computing Group. "And, with the introduction of 12th Gen Intel Core mobile processors, we are unlocking new experiences and setting the standard of performance with the fastest processor for a laptop—ever."

Razer, the leading global lifestyle brand for gamers (Hong Kong Stock Code: 1337), is kicking off 2022 with new Razer Blade gaming laptop models including the Razer Blade 14, Razer Blade 15, and Razer Blade 17. The world's fastest laptops for gamers and creators are equipped with the recently announced NVIDIA GeForce RTX 30 Series Laptop GPUs, up to an RTX 3080 Ti, making the new Blades better than ever, now shipping with Windows 11. All new Razer Blade gaming laptops now also include groundbreaking DDR5 memory, providing blistering clock speeds up to 4800 MHz, an increase in frequency by up to 50% compared to the previous generation.

"The Razer Blade series continues to be the best gaming laptop by providing desktop-class performance on-the-go," says Travis Furst, Senior Director of Razer's Systems business unit. "Additionally, we've enabled creators to work anywhere with gorgeous displays, available NVIDIA Studio drivers, and up to 14-Core CPUs. Users will have the ability to choose any model or configuration that best fits their gaming or creating needs, while getting the latest and greatest in graphics, memory and processing technology."

All six Intel 12th Gen Core "Alder Lake" processor models launched to date are unlocked (K or KF) SKUs, which lack a boxed cooling solution. This is expected to change early next year when Intel fleshes out the lineup with at least 10 new SKUs for the retail segment; and with "Alder Lake" marking the first major change to the mainstream desktop processor cooling mount in over a decade; Intel has the opportunity to radically change its cooling design. We got our first hint at what these could look like back in September, and we now have a clear picture of one of them.

There are three stock coolers Intel is preparing. The RH1 (high) will likely go with the top Core i9-12900 and i9-12900F parts. The RM1 (mid) could be bundled with various Core i7 and Core i5 SKUs; while the RS1 (small) could go with entry-level Core i3 SKUs. Here we have the RM1. Back in the September article, we were staring at low-resolution pictures and trying to guess what the heatsink design could look like. At the time we thought that the pointy structures into which the fan is nestled, are metallic extensions of the heatsink's fins, designed to make use of lateral bleed airflow from the fan. The new picture puts this theory to rest. Turns out, those are little more than an aesthetic touch.

Just yesterday, thanks to the Linux driver update, we found information stating that AMD's upcoming EPYC Genoa processor generation based on Zen 4 core IP will have a 12-channel memory controller. However, we didn't know how AMD engineered the memory controller of this processor generation and some of its maximum capabilities. However, there is an exciting discovery. According to the report from ComputerBase, with information exclusive to them, AMD will enable up to 12 TB of DDR5 memory spread across 12 memory channels. The processor supports DDR5-5200 memory, but when all 24 memory slots (two per channel) are populated, the DDR5 maximum speed drops to 4000 MT/s.

It is unclear why this is the case, and if any difficulties were designing the controller, so the maximum speed drops when every slot is used. One reassuring thing is that the bandwidth created by 12 memory channels should be sufficient to make up for the lost speed of DDR5 memory reduction.

According to some testing performed by the team behind RPCS3, a free and open-source emulation software for Sony's PlayStation 3, Intel's Alder Lake processors are enjoying a hefty performance boost when E-Cores is disabled. First of all, the Alder Lake processors feature a hybrid configuration with high-performance P-cores and low-power E-cores. The P-cores are based on Golden Cove architecture and can execute AVX-512 instructions with ease. However, the AVX-512 boost is only applicable when E-cores are disabled as software looks at the whole package. Officially, Alder Lake processors don't support AVX-512, as the processor's little E-cores cannot execute AVX-512 instruction.

Thanks to the team behind the RPCS3 emulator, we have some information and tests that suggest that turning E-cores off gives a performance boost to the emulation speed and game FPS. With E-Cores disabled, and only P-cores left, the processor can execute AVX-512 and gets a higher ring ratio. This means that latency in the ring bus is presumably lower. The team benchmarked Intel Core i9-12900K, and Core i9-11900K processors clocked at 5.2 GHz for tests. The Alder Lake chip had disabled E-cores. In God of War: Ascension, the Rocket Lake processor produced 68 FPS, while Alder Lake produced 78 FPS, representing around 15% improvement.

With Intel's Alder Lake processors released, the company introduced a rather interesting concept of mixing high-performance and high-efficiency cores into one design. This hybrid approach combines performance P-cores based on Golden Cove architecture with high-efficiency E-cores based on Gracemont design. While Intel dedicated a lot of effort to optimizing software for Alder Lake, there are sometimes issues that persist when playing older games. At the heart of ADL processors, a thread scheduler decides which task is running on P or E-cores and ensures the best core gets selected for the job.

However, many users know that E-cores can be recognized as another system by DRM software and cause troubles on the latest 12th Generation machines. GIGABYTE has designed a software tool for its Z690 motherboards to fix this issue, which allows on-demand enablement of E-cores. Users can easily "park" or "unpark" E-cores and enable some older game titles to run efficiently with the help of P-cores. This DRM Fix Tool is a lightweight utility that unfortunately runs exclusively on GIGABYTE motherboards. It is less than a megabyte in size and requires no particular installation. However, it is an excellent addition to GIGABYTE's customers, and all that it needs is the latest BIOS update to run. Here you can download the tool, and below, you can see the list of the latest BIOS versions of GIGABYTE Z690 motherboards that support this tool.

Intel's upcoming lineup of mobile processors with the novel hybrid core technology are codenamed Alder Lake-P. Contrary to the desktop Alder Lake-S, the P variant was envisioned with a lower power budget in mind to fit various form factors. Today, we get to see some of the first benchmarks of the Alder Lake-P processors and get to compare them to AMD's competing products. In the Geekbench 5 listing discovered by BechLeaks, Intel's Core i7-12800H processor with six performance and eight efficiency cores appear. The CPU ran at a base frequency of 2.8 GHz, while Geekbench didn't show boosting clocks in the submission.

The CPU managed to score 1654 points in single-core results and 9618 points in multi-core runs. If we compare this to AMD Ryzen 7 5800H, a direct competitor, the CPU is faster by 25% and 35% in single-core and multi-core results, respectively. If the previous Tiger Lake-H generation is a reference, the Alder Lake-P chip manages 12% and 20% higher single-core and multi-core scores. This specific processor is part of the GIGABYTE AORUS 15 YE4 laptop used for the Geekbench 5 benchmark test run.

AMD EPYC class of enterprise processors has gotten infected by as many as 22 different security vulnerabilities. These vulnerabilities range anywhere from medium to high severity, affecting all three generations of AMD EPYC processors. This includes AMD Naples, Rome, and Milan generations, where almost all three are concerned with the whole 22 exploits. There are a few exceptions, and you can find that on AMD's website. However, not all seems to be bad. AMD says that "During security reviews in collaboration with Google, Microsoft, and Oracle, potential vulnerabilities in the AMD Platform Security Processor (PSP), AMD System Management Unit (SMU), AMD Secure Encrypted Virtualization (SEV) and other platform components were discovered and have been mitigated in AMD EPYC AGESA PI packages."

AMD has already shipped new mitigations in the form of AGESA updates, and users should not fear if they keep their firmware up to date. If you or your organization is running on AMD EPYC processors, you should update the firmware to avoid any exploits from happening. The latest updates in question are NaplesPI-SP3_1.0.0.G, RomePI-SP3_1.0.0.C, and MilanPI-SP3_1.0.0.4 AGESA versions, which fix all of 22 security holes.

Intel's fourth-generation Core processors, codenamed Haswell, are subject to new security exploits. According to the company, a vulnerability exists inside the graphics controller of 4th generation Haswell processors, happening once the DirectX 12 API loading occurs. To fix the problem, Intel has found that disabling this API results in a fix. Starting with Intel graphics driver 15.40.44.5107 applications that run exclusively on DirectX 12 API no longer work with the following Intel Graphics Controllers: Intel Iris Pro Graphics 5200/5100, HD Graphics 5000/4600/4400/4200, and Intel Pentium and Celeron Processors with Intel HD Graphics based on 4th Generation Intel Core.

"A potential security vulnerability in Intel Graphics may allow escalation of privilege on 4th Generation Intel Core processors. Intel has released a software update to mitigate this potential vulnerability. In order to mitigate the vulnerability, DirectX 12 capabilities were deprecated." says the Intel page. If a user with a Haswell processor has a specific need to run the DirectX 12 application, they can downgrade their graphics driver to version 15.40.42.5063 or older.

The x86 instruction set architecture has experienced many issues, and today's announcement is no exception. Yesterday morning, the Linux kernel received an urgent set of patches that are supposed to fix "yet another hardware trainwreck," as Thomas Gleixner, the kernel developer, describes. This time, the problem occurs with the high precision event timer (HPET) that stops once x86 processors reach PC10 idle state. In that event, the timer stops even when the OS/kernel uses it and could potentially cause a vulnerability inside a processor that an attacker can exploit. The problem has been known for quite a while since, in 2019, the Linux kernel started removing HPET functionality from some Intel processors.

The priority of this patch for Linux Kernel version 5.15-rc5 is high and marked as an urgent update. A reliable hardware timer and an interrupt are a must for the proper function of a processor. The hardware fix for this will not happen soon, so the Linux kernel has to adapt to it and create a solution at the software level. According to Mr. Gleixner, "The probability that this problem is going to be solved in the forseeable future is close to zero, so the kernel has to be cluttered with heuristics to keep up with the ever growing amount of hardware and firmware trainwrecks. Hopefully some day hardware people will understand that the approach of "This can be fixed in software" is not sustainable. Hope dies last..."

AMD today announced a goal to deliver a 30x increase in energy efficiency for AMD EPYC CPUs and AMD Instinct accelerators in Artificial Intelligence (AI) training and High Performance Computing (HPC) applications running on accelerated compute nodes by 2025.1 Accomplishing this ambitious goal will require AMD to increase the energy efficiency of a compute node at a rate that is more than 2.5x faster than the aggregate industry-wide improvement made during the last five years.

Accelerated compute nodes are the most powerful and advanced computing systems in the world used for scientific research and large-scale supercomputer simulations. They provide the computing capability used by scientists to achieve breakthroughs across many fields including material sciences, climate predictions, genomics, drug discovery and alternative energy. Accelerated nodes are also integral for training AI neural networks that are currently used for activities including speech recognition, language translation and expert recommendation systems, with similar promising uses over the coming decade. The 30x goal would save billions of kilowatt hours of electricity in 2025, reducing the power required for these systems to complete a single calculation by 97% over five years.

With the 15.6 and 17.3 inch XMG APEX gaming laptops, XMG is positioning a new model series below its own high-end range consisting of the NEO and PRO series. These new laptops combine mobile AMD eight-core processors up to the Ryzen 9 5900HX with NVIDIA GeForce RTX graphics cards up to the RTX 3070. The company is simultaneously introducing the XMG FOCUS, a new product series in the entry-level segment. Intel's Core i7-11800H and an NVIDIA GeForce RTX 3050 Ti offer decent gaming performance, while good connectivity and memory round off the overall package. All four new models feature an IPS display with 144 Hz.

Until now, the XMG APEX 15 in the older E20 generation represented uncompromising desktop CPU performance, with processors up to the Ryzen 9 3950X in a laptop. Although XMG is already working on a direct successor under a slightly different name, it is unleashing the XMG APEX 15 and APEX 17 of the M21 generation for the time being with the currently fastest eight-core mobile processors from AMD. The laptops are available with an AMD Ryzen 7 5800H as well as with the slightly faster Ryzen 9 5900HX from the 54 watt TDP class, as well as with an NVIDIA GeForce RTX 3070 or RTX 3060 in the respective maximum TGP configuration (RTX 3070: 125 watts plus 15 watts Dynamic Boost 2.0; RTX 3060: 115 watts plus 15 watts Dynamic Boost 2.0).

AMD is slowly preparing the launch of the latest and greatest Ryzen processor family based on the Zen 4 CPU core design. Among various things that are getting an overhaul, the Raphael processor generation is now getting revamped temperature reading and better power management circuitry. According to an Igor's Lab report, AMD has prepared a few new improvements that will make temperature reading and power management easier for PC enthusiasts. Currently, the reported CPU temperature is called Tcontrol (Tctl), which is what the cooling solution sees. If Tctl is high, the fans spin up and cool the system. If Tctl is low, the fans slow down to reduce noise.

With Raphael, the CUR_TEMP (current temperature) output part of Tctl has been upgraded to reflect a much smoother curve, and avoid jittering with fans as they are not spiking so suddenly anymore. This is helping contribute to the noise output and has made it run at a consistent fan speed in the system. Another note about Raphael is a new power management technique. AMD has designed the AM5 platform to avoid sudden power spikes, to maintain maximum efficiency over time. It is a design decision made from the very start, and the CPU will try to constrain itself in the TDP range that it is configured for. For more details about the circuitry, please head over to the Igor's Lab article.

[Editor's note: We have published the review of HYTE Revolt 3 Case here.]

HYTE, the new PC components and lifestyle brand of iBUYPOWER, a leading manufacturer of high-performance custom gaming PCs, today released its premier product, the Revolt 3 Mini-ITX PC case. Previously announced during CES 2021 as the Revolt 3 MK3, the Revolt 3 was designed with careful consideration for DIY PC enthusiasts, gamers, and creators alike.

"iBUYPOWER is excited to introduce its new sub-brand, HYTE, to our community with its very first product, the Revolt 3" said Darren Su, Executive Vice President of iBUYPOWER. "With over 20 years of experience as a systems integrator we felt like we had a unique perspective to bring to the table when developing PC Components. We approached the Revolt 3 with the goal of designing a case with the freedom and flexibility that would allow the use of a wide range of components without imposing performance restrictions based on the size of the case."

Intel's upcoming Alder Lake processor family is set to bring a mixture of big and little cores, combined into one package designed for the hybrid way of computing. Alongside the CPU cores, Intel is also etching integrated graphics into the Alder Lake silicon. However, according to Komachi (@KOMACHI_ENSAKA), there will be Alder Lake SKUs that don't feature a working integrated GPU. Just like we witnessed Intel produce "F" models for its past few generations of Core processors, we could see a re-appearance of the F SKUs with Alder Lake as well. In the leaked listing, Komachi notes the appearance of Intel Core i5-12600KF, Core i7-12700KF, and Core i9-12900KF.

All of the listed models are overclockable SKUs, just with their integrated graphics disabled. Just like the previous generation, Intel decided to introduce this SKU, giving customers a few benefits with the non-functional iGPU. As there is no GPU to produce heat, overclocking efforts could be much better on the "F" SKUs. In addition to that, these SKUs could be a bit cheaper compared to the regular models, saving the buyers some spare cash if they are going to purchase a 3rd party dedicated GPU anyway.

Intel today announced AWS customers can access the latest 3rd Gen Intel Xeon Scalable processors via the new Amazon Elastic Compute Cloud (Amazon EC2) M6i instances. Optimized for high-performance, general-purpose compute, the latest Intel-powered Amazon EC2 instances provide customers increased flexibility and more choices when running their Intel-powered infrastructure within the AWS cloud. Today's news is a further continuation of Intel and AWS' close collaboration, giving customers scalable compute instances in the cloud for almost 15 years.

"Our latest 3rd Gen Intel Xeon Scalable processors are our highest performance data center CPU and provide AWS customers an excellent platform to run their most critical business applications. We look forward to continuing our long-term collaboration with AWS to deploy industry-leading technologies within AWS' cloud infrastructure." -Sandra Rivera, Intel executive vice president and general manager, Datacenter and AI Group.

The leading global motherboard, graphics card, and small form factor PC manufacturer, ASRock, has released the latest BIOS that support AMD Ryzen 5000 G-Series Desktop Processors with Radeon Graphics and AMD Ryzen 5000 Series Desktop Processors with PRO Technologies.

AMD Ryzen 5000 G-Series Desktop Processors with Radeon Graphics are the newest generation processors come with industry-leading 7nm technology, elevating processing performance to the next level. And now, ASRock 500-Series, B450 AMD Ryzen motherboards and X300 Mini PC are able to support both of them by updating the latest BIOS.
