We have already witnessed a multitude of rumors surrounding the Legion Go S gaming handheld. The product is expected to boast an AMD Ryzen Z2 chip, which, unfortunately, will be based on the older Zen 3+ architecture and features a Radeon 680M iGPU. The system will include 16 GB of LPDDR5 memory, and an 8-inch, 1200p IPS display with a 120 Hz refresh rate. As for pricing, the Legion Go S is expected to cost around €600, and most likely cheaper outside of Europe, putting it in the ballpark of the Steam Deck OLED. Now, leaker Evan Blass has shared a few more images of the device, further revealing a few more details.

Firstly, the image reveals the colorways that the Legion Go S will be available in: black and white. Interestingly, the image also reveals what appears to be a button that is dedicated for Steam, which, so far, we have only seen in the Steam Deck. As VideoCardz notes, there is no concrete information at the moment regarding the purpose of the button. It is possible that the Legion Go S might run SteamOS, although the button might also exist to simply open up Steam. Unfortunately, the leak gives us no further information regarding the product. The Legion Go S is expected to see the light of day at CES 2025, which, luckily for us, happens to be just around the corner.

AMD Ryzen 7 5800X3D has hit end-of-life, according to a ComputerBase.de report. Introducing the new 3D V-cache technology, the 5800X3D breathed life back into the Socket AM4 platform as Intel debuted its 12th Gen Core "Alder Lake" processors, while there was still some time to go before AMD could mount up a defense with Ryzen 7000 "Zen 4." AMD figured out a way to augment the 32 MB on-die L3 cache with an additional 64 MB stacked cache that appears as a contiguous 96 MB addressable block to software. Having such a large fast cache next to the CPU cores greatly enhances performance in gaming workloads.

The 5800X3D was able to match the gaming performance of Intel's flagship Core i9-12900K despite being based on the generationally older "Zen 3" microarchitecture, and being restricted with older DDR4 memory. It would go on to be an incredible upgrade option for those still on the Socket AM4 platform, giving them performance in league with Intel's 12th- and 13th Gen processors. As of this writing, US retailer Newegg no longer has the 5800X3D in stock. Amazon has it, and so do some of the smaller retailers. Across the pond, the chip is vanishing from European retailers. In the absence of the 5800X3D, users still have the option of the Ryzen 7 5700X3D and the 6-core 5600X3D, which were both launched in the last year.

AMD announced that its Ryzen processor branch prediction optimization that provide gaming performance uplifts, is now available for Windows 11 23H2, through an optional update. This update applies to AMD Ryzen processors based on the "Zen 3," "Zen 4," and "Zen 5" microarchitectures, and essentially yields the kind of performance you get in the real Administrator account, on regular Windows accounts, especially non-local (online) accounts. Users should look for "Cumulative Update Preview for Windows 11 Version 23H2 for x64-based Systems (KB5041587)" in Windows Update, which should begin showing up as an optional update. This update requires a system restart to apply.

With this update in place, gaming performance uplifts between Windows 11 23H2 and 24H2 should be identical. "We wanted to let you know that the branch prediction optimization found in Windows 11 24H2 has now been backported to Windows 11 23H2. Users will need to look for KB5041587 under Windows update > Advanced options > Optional updates. We expect the performance uplift to be very similar between 24H2 and 23H2 with KB5041587 installed," AMD said in a statement to Wccftech.

AMD Ryzen 9000 "Granite Ridge" desktop processors have been out for a couple of weeks now, and the "Zen 5" based processors have fallen short of gaming performance expectations, set mainly by some of the numbers AMD put out in its Computex 2024 reveal for the processors. The consensus among the tech press is that these processors are roughly 3-5% faster than Ryzen 7000 series "Raphael," but with noteworthy improvements in energy efficiency. AMD set out to study why there are such vast deltas in performance between its numbers and those of reviews, and arrived a few possible explanations. The company also stated that it is working with Microsoft to fix this in the next major update to Windows 11.

One of them is that AMD's testing was done on Windows 11 23H2 with Admin mode (i.e. a local system administrator account was used), while some reviewers tested with a regular user account that has some admin privileges. Apparently this affects the way the branch prediction units of "Zen 5" processors work. "Our automated test methodology was run in "Admin" mode which produced results that reflect branch prediction code optimizations not present in the version of Windows reviewers used to test Ryzen 9000 Series," AMD said in a statement.

If you're on the Socket AM4 platform, AMD is never gonna give you up, never gonna let you down, never gonna run around and desert you; never gonna make you cry, never gonna say goodbye, never gonna tell a lie, and hurt you. The company is reportedly giving finishing touches to a firecracker of a sub-$200 chip for price-conscious gamers, the Ryzen 5 5500X3D. That's right, AMD is bringing 3D V-cache technology to the mid-range, with a new 6-core processor based on the "Zen 3" microarchitecture, but enjoying the gaming performance boost from 96 MB of L3 cache on tap.

AMD already has a 6-core X3D Socket AM4 chip, the Ryzen 5 5600X3D, which joined the product stack a couple of years after AMD's original Ryzen 7 5800X3D took the gaming PC processor scene by storm, matching the then swanky new Core i9-12900K "Alder Lake" despite being based on an older-generation "Zen 3" architecture. Not much else is known about the 5500X3D, except that it could have a lower clock speed than the 5600X3D. Back in November 2023, when news of the 5700X3D first hit the scene, the 5500X3D was rumored to be a 6-core/12-thread chip with 3.00 GHz base frequency and 4.00 GHz maximum boost, compared to the 3.30 GHz base and 4.40 GHz boost frequency of the 5600X3D. Given that AMD launched the 5600X3D at $230, AMD could target a sub-$200 price point to wow gamers on AM4, such as $199.

An AMD Ryzen 5 9600X "Zen 5" processor engineering sample has been overclocked to 5.70 GHz on all cores, and put through the CPU-Z Benchmark. Here, the chip is found to score 871 points in the single-thread benchmark, and 7096 points in the multithreaded benchmark. The overclock to 5.70 GHz is significant, as this is the maximum boost frequency of the upcoming Ryzen 9 9950X flagship part. The single-thread benchmark highlights that "Zen 5" has a similar IPC to the "Raptor Cove" P-core of the Intel Core i9-14900K processor, while the 7096 points multithreaded score is higher than the that of the Ryzen 7 5800X "Zen 3," meaning that AMD is overcoming the deficit of two whole cores (33% of the core-count of the 9600X) with just IPC and faster memory. AMD is expected to launch the Ryzen 9000 series desktop processors in July 2024.

AMD Socket AM4 is now an 8-year-old platform, since its debut back in 2016. AMD objectively went above and beyond for this platform, launching processors powered by the original "Zen," the refreshed "Zen+," the "Zen 2," and the Intel-beating "Zen 3" microarchitecture, including 3D V-cache versions of the "Zen 3" that were competitive even with Intel's 12th Gen Core "Alder Lake" processors in gaming. Those on older processors on AM4 are spoiled for choice with upgrades within the platform, without having to change it, with AMD releasing new processor models every year for the past 8 years. The 2024 launches include the Ryzen 5000XT series.

It's hard to call the Ryzen 5000XT a "series," since there are only two SKUs—the Ryzen 9 5900XT, and the Ryzen 7 5800XT. Neither of the two feature 3D V-cache, but push clock speeds up. The Ryzen 9 5900XT is a 16-core/32-thread part, and is not meant to be confused with the 5900X, which is a 12-core/24-thread part. The 16-core 5900XT comes with a maximum boost frequency of 4.80 GHz, which is 100 MHz less than that of the 5950X. It has the same 105 W TDP, and a significantly lower $360 price. The Ryzen 7 5800XT, on the other hand, is an 8-core/16-thread chip with 4.80 GHz maximum boost frequency, compared to the 4.70 GHz of the 5800X, and the same 105 W TDP. It's priced around $260. Both chips include an AMD Wraith Prism RGB cooler that's capable of handling 140 W TDP processors. The Ryzen 9 5900XT is claimed by AMD to offer similar gaming performance to the Intel Core i7-13700K; while the 5800XT is claimed to play games competitively to the Intel Core i5-13600KF. Both chips should be available sometime in July, 2024.

Amid all the attention the next-generation "Lion Cove" P-cores powering the upcoming "Lunar Lake" and "Arrow Lake" microarchitectures get as they compete with AMD's "Zen 5," it's easy to lose sight of the next-generation "Skymont" E-cores that will feature in both the upcoming Intel microarchitectures, and as standalone cores in the "Twin Lake" low-power processor. Pictures from an Intel presentation, possibly to PC OEMs, got leaked to the web. These are just thumbnails, we can't see the whole slides, but the person who took the pictures captioned them in a now-deleted social media post on the Chinese microblogging platform Weibo.

And now, the big reveal—the "Skymont" E-core is said to offer a double-digit IPC gain over the "Crestmont" E-core powering the current "Meteor Lake" processor, which in itself posted a roughly 4% IPC gain over the "Gracemont" E-cores found in the "Raptor Lake" and "Alder Lake" microarchitectures. Such an IPC gain over "Gracemont" should make the "Skymont" E-core match the IPC of the "Sunny Cove" or "Willow Cove" P-cores powering the "Ice Lake" and "Tiger Lake" microarchitectures, respectively, which were both within the 90th percentile of the AMD "Zen 3" core in IPC.

AMD classified the Zenbleed vulnerability, CVE-2023-20593, as a medium-level threat about a year ago. AMD has acknowledged that it could potentially allow an attacker to access sensitive information under certain microarchitectural circumstances. Today, MSI has released new BIOS updates featuring AMD's AM4 AGESA 1.2.0.Ca firmware update. This update addresses the Zenbleed vulnerability affecting AMD's Ryzen 4000 series Zen 2 APUs. MSI is proactively rolling out the new BIOS updates across its range of compatible motherboards. The updates are currently available for almost all X570 motherboards, with support for other chipsets and 400 series motherboards expected to follow soon.

The AGESA 1.2.0.Ca firmware update specifically targets the Zenbleed vulnerability in the Zen 2 microarchitecture. Although the vulnerability primarily affects Ryzen 4000 "Renoir" APUs, it also exists in other Zen 2 processors, including the Ryzen 3000 series and certain EPYC and Threadripper CPUs. AMD has already addressed the Zenbleed vulnerability in previous AGESA microcode updates for Ryzen 3000 processors and other platforms, such as EPYC server CPUs and Ryzen mobile CPUs. However, the Ryzen Embedded V2000 CPUs are still awaiting the EmbeddedPi-FP6 1.0.0.9 AGESA firmware update, which is expected to be released by April. While AMD has not explicitly stated whether the security update will impact performance, previous testing of Zenbleed fixes has shown potential performance drops of up to 15% in certain workloads, although gaming performance remained relatively unaffected. Users with AM4 chips based on architectures other than Zen 2, such as Zen+ or Zen 3, do not need to update their BIOS as they are not affected by this specific vulnerability.

SolidRun, a leading developer and manufacturer of high-performance System on Module (SOM) solutions, Single Board Computers (SBC) and network edge solutions, today announced the launch of its new Ryzen V3000 CX7 Com module, configurable with the 8-core/16-thread Ryzen Embedded V3C48 Processor. Boasting AMD's state-of-the-art 6 nm "Zen 3" architecture, this ultra-powerful embedded solution offers industry-leading performance and power efficiency. As SolidRun's first x86-based Com Express 7 module, the Ryzen V3000 CX7 Com module ushers in a new era of efficient, high-performance computing for a diverse range of networking and edge applications.

"Our new Ryzen V3000 CX7 Com module is an exciting addition to our CX7 product line as it represents a significant leap forward in embedded computing and offers unmatched performance and scalability for networking and edge applications," said Dr. Atai Ziv, CEO at SolidRun. "By leveraging the power of AMD's Ryzen Embedded V3000 processor, we are empowering developers to create innovative solutions that meet the evolving demands of modern embedded computing."

Huawei's new server CPU based on the HiSilicon Taishan V120 core has shown impressive single-threaded performance that matches AMD's Zen 3 architecture in a leaked Geekbench 6 benchmark. The Taishan V120 is likely being manufactured on SMIC's 7 nm process node. The Geekbench 6 result posted on social media does not identify the exact Huawei server CPU model, but speculation points to it being the upcoming Kunpeng 930 chip. In the benchmark, the Taishan V120 CPU operating at 2.9 GHz scored 1527 in the single-core test. This positions it nearly equal to AMD's EPYC 7413 server CPU based on the Zen 3 architecture, which boosts up to 3.6 GHz and which scored 1538 points. It also matches the single-threaded performance of Intel's Coffee Lake-based Xeon E-2136 from 2018, even though that Intel chip can reach 4.5 GHz boost speeds, scoring 1553 points.

The Taishan V120 core first appeared in Huawei's Kirin 9000 smartphone SoC in 2020. Using the core in server CPUs would allow Huawei to achieve competitive single-threaded performance to rival AMD's last-generation EPYC Milan and Intel's older Skylake server chips. Multi-threaded benchmarks will be required to gauge the Kunpeng 930's overall performance fully when it launches. Huawei continues innovating its ARM-based server CPU designs even while facing restrictions on manufacturing and selling chips internationally due to its inclusion on the US Entity List in 2019. The impressive single-threaded results versus leading x86 competitors demonstrate Huawei's resilience and self-reliance in developing homegrown data center technology through its HiSilicon division. More details on the Kunpeng 930 server chip will likely surface later this year, along with server configurations from Chinese OEMs.

BIOSTAR, a leading manufacturer of motherboards, graphics cards, and storage devices today, announces that its AMD AM4 series motherboards are now compatible with the latest AMD Ryzen 5000 series processors.With the official unveiling of the Ryzen 8000 Series desktop processors, AMD has further enhanced its Ryzen 5000 Series, first released in 2020, by introducing four new processors. These additions include the Ryzen 7 5700X3D, Ryzen 7 5700, Ryzen 5 5600GT, and Ryzen 5 5500GT, all built on AMD's efficient Zen 3 architecture. This expansion of the Ryzen 5000 Series offers users a broader range of options, from high-end to mainstream, demonstrating AMD's dedication to diversifying its CPU offerings.

The AMD Ryzen 7 5700X3D and Ryzen 7 5700 processors are equipped with advanced technologies like AMD StoreMI, which enhances storage performance by combining SSDs and HDDs into a more efficient, single-tiered storage system. Additionally, they support AMD Ryzen VR-Ready Premium technology, offering greater immersion in virtual reality, even on older hardware. This combination of StoreMI and VR-Ready Premium technology ensures these processors deliver high storage efficiency and an enhanced VR experience, making them suitable for a wide range of demanding applications.

AMD Socket AM4 continues to be relevant even in 2024, nearly seven years since its introduction, with the company announcing several new processor models at CES. AMD has extended Ryzen 5000 series "Zen 3" support across all three desktop chipset series, including the oldest AMD 300-series, and since all Socket AM4 motherboards feature USB BIOS Flashback, users have the full spread of Socket AM4 processors to upgrade to. The Ryzen 7 5800X3D continues to be a popular final upgrade destination for gamers on Socket AM4 who may have spent a pretty penny building a high-end gaming desktop in 2020-21. The 5800X3D offers gaming performance comparable to an Intel Core i9-12900K "Alder Lake," despite being based on the older "Zen 3" microarchitecture, since it enjoys a large 96 MB L3 cache, thanks to AMD's innovative 3D Vertical Cache technology. The 5800X3D commands a $360 street price, which may be a little steep for some users, and so AMD is increasing choice, with the introduction of the new Ryzen 7 5700X3D.

The Ryzen 7 5700X3D is an 8-core/16-thread Socket AM4 processor, which is practically the same silicon as the 5800X3D, but with lower clock speeds, and more importantly a 30% lower price. While the 5800X3D commands $360 in the market, the new 5700X3D is coming in at an attractive $250. The 5700X3D comes with a base frequency of 3.00 GHz, and maximum boost frequency of 4.10 GHz. In comparison the 5800X3D has a 3.40 GHz base frequency, and 4.50 GHz boost. Both chips enjoy the same power limits, with a TDP of 105 W. The 5700X3D gets the same 96 MB of L3 cache that includes 64 MB of 3D Vertical Cache; and 512 KB of L2 cache per core. The I/O is identical, too, with a 24-lane PCI-Express Gen 4 interface, and dual-channel DDR4 memory, with DDR4-3600 being the sweetspot frequency.Update Jan 9th: AMD clarified the specs of the Ryzen 5 5500GT in an updated slide. It is indeed a 6-core/12-thread processor.

The AMD Socket AM4 platform is still alive and kicking, with AMD releasing new processor models in its 7th year. Many of these chips started selling online in Europe. The Ryzen 7 5700X3D is a slightly lower clocked version of the 5800X3D, which for many of those still on AM4 is the final upgrade to their platform. The 5800X3D may be based on the older "Zen 3" microarchitecture, but thanks to its 3D Vertical Cache technology, offers gaming performance comparable to the Core i9-12900K "Alder Lake," making even 7-year old AM4 gaming desktops contemporary. To cash in on this exact market, AMD released a more cost-effective option, the Ryzen 7 5700X3D.

The 5700X3D is an 8-core/16-thread Socket AM4 processor that features 96 MB of L3 cache thanks to the 3D V-cache technology, just like the 5800X3D, but comes with a maximum boost frequency of 4.10 GHz, compared to the 4.50 GHz of the 5800X3D. Store listings do not mention its TDP or base frequency. The 5700X3D is being listed at 271€ including taxes, or about 15-20% cheaper than the 5800X3D. A word of caution when choosing the 5700X3D would be its close to non-existent overclocking headroom, so this probably isn't a chip that you can manually overclock to performance levels of a 5800X3D while saving some 40€ on the side.

AMD is preparing to update its desktop processor lineup not just with new Ryzen 8000G series APUs for the Socket AM5 platform, but also a handful new SKUs for AM4. Possible pricing of many of these chips is detailed in our recent report. Among the chips listed is a mysterious new Ryzen 7 5700 Socket AM4 processor. Although we don't have its pricing, AMD sneakily put up its product information on its website. On the product page, the company says that the product came out in April 2022, but it never did, at least not in the retail channel.

The Ryzen 7 5700 is an 8-core/16-thread processor that lacks integrated graphics, and yet is based on the 7 nm "Cezanne" monolithic silicon, with similar clock speeds to the Ryzen 7 5700G APU. Think of this as the 5700G with its iGPU disabled. The chip comes with a CPU base frequency of 3.70 GHz compared to the 3.80 GHz of the 5700G, although the two have an identical maximum boost frequency of 4.60 GHz. Each of the eight "Zen 3" CPU cores has 512 KB of dedicated L2 cache, and share a 16 MB L3 cache. The processor's TDP is set to 65 W, and the retail package includes a Wraith Stealth cooling solution. One pitfall of choosing the 5700 over something like the 5700X would be its lack of a PCIe Gen 4 interface (it's limited to the older Gen 3), which would mean a slower NVMe storage sub-system.

The Chinese chipmaker Loongson has launched its newest desktop processors, the 4-core, 8-thread 3A6000 series, based on the company's LoongArch microarchitecture. We have previously reported that the company wants to match Intel's "Willow Cove" and AMD's Zen 3 instruction per clock (IPC) levels with its 3A6000 CPU series, and today we have the first preview of the performance. Powered by the LA664 cores, 3A6000 is built on a 14/12 nm manufacturing process, with clock speeds going from 2.0 to 2.5 GHz and power consumption of up to 50 Watts. It features 256 KB of L2 cache and 16 MB of L3 cache in total.

While several hardware partners are announcing new Loongson-powered solutions, ASUS China's "Uncle Tony" managed to get his hands on one of them and overclocker the CPU to 2.63 GHz on air cooling. In overclocking tests using liquid nitrogen cooling, a 3A6000 processor reached 3.0 GHz, though there are indications that there is still overhead. In standard out-of-the-box configuration, the 3A6000 performs similarly to Intel's Core i3-10100 four-core CPU, an achievement for Loongson but still behind Intel's latest offerings that clock nearly twice as high. This rapid development of Loongson IP has led to a massive performance increase, matching the IPC of modern CPUs. We are still left to see more information about these 3A6000 series SKUs; however, early benchmarks suggest a significant improvement. You can see the CPU benchmarks below, which include UnixBench and SPEC CPU 2006.

AMD Socket AM4 users are in for a treat, as the company plans two more processor models in the Ryzen 5000X3D series, according to chi11eddog, a reliable source with AMD leaks. Although based on the older "Zen 3" microarchitecture, these chips feature 3D Vertical Cache technology, which helps shore up their gaming performance to levels comparable at least to 12th Gen Intel Core "Alder Lake," giving Socket AM4 platform users a cost-effective upgrade path to prolong their gaming PC builds that could be as old as 5 years now. If you recall, AMD has formally extended "Zen 3" and 3D V-cache support to all Socket AM4 chipset generations, including AMD 300-series.

Among the two new processor models are the Ryzen 7 5700X3D, and the Ryzen 5 5500X3D. The 5700X3D is an 8-core/16-thread processor with 100 MB of total cache (that's 512 KB of L2 cache per core, plus 96 MB of L3 cache); while the Ryzen 5 5500X3D is a 6-core/12-thread chip with 99 MB of total cache. What sets the 5700X3D and 5500X3D apart from the 5800X3D and 5600X3D are lower clock speeds, and possibly, lower TDP. Both chips come with a base frequency of 3.00 GHz, compared to the 3.30 GHz of the 5600X3D and 3.40 GHz of the 5800X3D. The 5700X3D boosts up to 4.10 GHz compared to the 4.50 GHz of the 5800X3D; while the 5500X3D boosts up to 4.00 GHz when compared to 4.40 GHz of the 5600X3D. Both the 5800X3D and 5600X3D have their TDP rated at 105 W, so it's possible that AMD is using lower TDP and PPT values for the 5700X3D and 5500X3D. There's no word on when the two new chips are coming out, although AMD continues to release updates to the Socket AM4 AGESA microcode, with the latest version ComboAM4v2 1.2.0.B being released as recently as September 2023.

AMD Ryzen processors with 3D Vertical Cache technology, denoted with the "X3D" brand extension on processor model numbers, are showing unexpected popularity numbers with close to a quarter of respondents to a TechPowerUp Frontpage Poll question saying that they use one. In August, we asked our readers if they use a Ryzen X3D processor. The question was "Are you using an AMD Ryzen X3D CPU with 3D V-Cache?" This was a few months into the launch of the Ryzen 7000X3D processor series that restored the gaming performance leadership for AMD against Intel's 13th Gen Core "Raptor Lake" processors.

Since the poll went live in August, we've seen 31,862 responses. From these, 14,732, or 46% say that they use a classic Ryzen processor (one without 3D V-cache). followed by 9,780 or 31% saying they use an Intel processor; an impressive 4,316 or 14% saying they use a Socket AM4 Ryzen 5000X3D series processor (5800X3D or 5600X3D); followed by 3,034 or 10% saying they use the latest 7000X3D series "Zen 4" processors. The X3D series together make 7,350 votes, or 23%.

A couple of slides from AMD's internal presentation were leaked to the web by Moore's Law is Dead, referencing what's allegedly the next-generation "Zen 5" microarchitecture. Internally, the performance variant of the "Zen 5" core is referred to as "Nirvana," and the CCD chiplet (CPU core die) based on "Nirvana" cores, is codenamed "Eldora." These CCDs will make up either the company's Ryzen "Granite Ridge" desktop processors, or EPYC "Turin" server processors. The cores themselves could also be part of the company's next-generation mobile processors, as part of heterogenous CCXs (CPU core complex), next to "Zen 5c" low-power cores.

In broad strokes, AMD describes "Zen 5" as introducing a 10% to 15% IPC increase over the current "Zen 4." The core will feature a larger 48 KB L1D cache, compared to the current 32 KB. As for the core itself, it features an 8-wide dispatch from the micro-op queue, compared to the 6-wide dispatch of "Zen 4." The integer execution stage gets 6 ALUs, compared to the current 4. The floating point unit gets FP-512 capabilities. Perhaps the biggest announcement is that AMD has increased the maximum cores per CCX from 8 to 16. At this point we don't know if it means that "Eldora" CCD will have 16 cores, or whether it means that the cloud-specific CCD with 16 "Zen 5c" cores will have 16 cores within a single CCX, rather than spread across two CCXs with smaller L3 caches. AMD is leveraging the TSMC 4 nm EUV node for "Eldora," the mobile processor based on "Zen 5" could be based on the more advanced TSMC 3 nm EUV node.

Giga Computing, a subsidiary of GIGABYTE and an industry leader in high-performance servers, workstations, and mini-PCs, today announced a newly designed ultra-compact, mainstream mini-PC for the GIGABYTE BRIXs lineup that adopts AMD Ryzen 7030 series processors. With AMD Zen 3 architecture and TSMC 7 nm process, AMD advanced its high-performance, efficient mobile processors for the mobile market to multitask and stay entertained. Even while adopting a compact size, all new mainstream BRIXs still delivers powerful computing that fits perfectly in any IoT deployment, whether for office use, education use, home use, digital signage, medical care, or KIOSK.

The most recent generation of mainstream BRIXs products in 2023 adopt an all-new chassis design. Computing performance has increased, but the design does not require an increase in the size of the chassis. Its appearance has curved, soft, and twisted lines with a liveliness that makes it very unobtrusive. By the way it was assembled and layered, and designing oblique angles around the base, a sense of simplicity is created to achieve a lightweight design. This allows users to enjoy ultimate computing performance while also having a stylish and elegant product.

Gamers Nexus has uploaded a video feature dedicated to the history of AMD's Zen CPU architecture—editor-in-chief and founder Stephen Burke ventured to Team Red's Austin, Texas-based test and engineering campus. Longer and more in-depth coverage of his lab tour will be released at a later date, but today's upload included an interesting segment covering unreleased hardware. The Gamers Nexus crew spent some time looking at several examples of current and past generation AMD 3D V-Cache CPUs. Prototype Ryzen 7000-series Zen 4 designs were shown off by principal engineer Amit Mehra and technical team member Bill Alverson. They also brought out older 5000-series Zen 3 units that never reached retail—the 16-core Ryzen 9 5950X3D was demonstrated as having a 3.5 GHz base clock, and it can boost up to 4.1 GHz. The 12-core Ryzen 9 5900X3D had 3.5 GHz base and 4.4 GHz boost clocks.

Team Red only sells one AM4 3D V-Cache model at the moment, in the form of its well received Ryzen 7 5800X3D CPU. It was released over a year ago, but recent price cuts have resulted in increased unit sales—system builders looking to maximize the potential of their older generation Ryzen 5000-series compatible mainboards are snapping up 5800X3Ds. AMD could be readying a cheaper alternative, with previous reports proposing that a "Ryzen 5 5600X3D" is positioned to take on Intel's 13th Gen Core i5 series (with DDR4). The unreleased Ryzen 9 5950X3D and 5900X3D have 3D V-Cache stacks on both of their CCDs (granting 192 MB of L3 cache), which is unique given that all retail 3D V-Cache CPUs (released so far) restrict this to a single CCD stack. Apparently AMD decided to stick with the latter setup due to it offering the best balance of performance and efficiency, plus gaming benchmarks demonstrated that there was not much of a difference between the configurations.

AMD is finally coming around to the idea of a 6-core processor with 3D Vertical Cache technology, only this time it's for the older Socket AM4 platform. The new Ryzen 5 5600X3D could be positioned competitively against the lower end of Intel's 13th Gen Core i5 processor series, so it could attract a class of DIY gaming PC builders that can take advantage of cheap Socket AM4 motherboards and DDR4 memory to build formidable mainstream gaming PC builds.

The Ryzen 5 5600X3D is based on the same "Vermeer" 3DV cache MCM as the 5800X3D. It is a 6-core/12-thread processor with a base frequency of 3.30 GHz, and 4.40 GHz boost, which are both 100 MHz less than those of the 5800X3D. The processor gets the full 96 MB of last-level cache (that's 32 MB of on-die L3 cache + 64 MB of 3DV cache), which the 5800X3D offers. It bears the OPN "100-000001176." The company didn't reveal pricing, but given that the 5800X3D can be had for as low as $290, the 5600X3D could possibly target a $200-225 price, making it an attractive option, given that you can pair it with even cheap B450 chipset motherboards priced well under $100, and 32 GB of DDR4 memory that can be had around the $60-mark. The 5600X3D could also provide an affordable upgrade path to those still on the AM4 platform, with Ryzen 3000-series processors.

Chinese company Loongson, specializing in creating processors for usage in mainland China, has been steadily working on enabling its next-generation Loongson 3A6000 CPUs. Aiming to provide the performance level of Intel Willow Cove and AMD Zen 3, these new CPUs will use Loongson's custom LoongArch Instruction Set Architecture (ISA) with a new set of 64-bit superscalar LA664 cores. Today, thanks to the report from Phoronix, we find out that Loongson has submitted some Linux patches that enable the upcoming 3A6000 CPUs to work with Linux-based operating systems at launch. Interestingly, as the new CPU generation gets closer to launch, more Linux kernel patches begin to surface.

Today's kernel patches focus on supporting the hardware page table walker (PTW). As PTW can handle all fast paths of TLBI/TLBL/TLBS/TLBM exceptions by hardware, software only needs to handle slow paths such as page faults. Additionally, in the past, LoongArch utilized "dbar 0" as a complete barrier for all operations. However, this full completion barrier severely impacted performance. As a result, Loongson-3A6000 and subsequent processors have introduced various alternative hints. Loongson plans to ship samples to select customers in the first half of 2023, so we could see more information surfacing soon.

Researchers at the Technical University of Berlin have published a paper called "faulTPM: Exposing AMD fTPMs' Deepest Secrets," highlighting AMD's firmware-based Trusted Platform Module (TPM) is susceptible to the new exploit targeting Zen 2 and Zen 3 processors. The faulTPM attack against AMD fTPMs involves utilizing the AMD secure processor's (SP) vulnerability to voltage fault injection attacks. This allows the attacker to extract a chip-unique secret from the targeted CPU, which is then used to derive the storage and integrity keys protecting the fTPM's non-volatile data stored on the BIOS flash chip. The attack consists of a manual parameter determination phase and a brute-force search for a final delay parameter. The first step requires around 30 minutes of manual attention, but it can potentially be automated. The second phase consists of repeated attack attempts to search for the last-to-be-determined parameter and execute the attack's payload.

Once these steps are completed, the attacker can extract any cryptographic material stored or sealed by the fTPM regardless of authentication mechanisms, such as Platform Configuration Register (PCR) validation or passphrases with anti-hammering protection. Interestingly, BitLocker uses TPM as a security measure, and faulTPM compromises the system. Researchers suggested that Zen 2 and Zen 3 CPUs are vulnerable, while Zen 4 wasn't mentioned. The attack requires several hours of physical access, so remote vulnerabilities are not a problem. Below, you can see the $200 system used for this attack and an illustration of the physical connections necessary.

AMD announced that it is bundling "Company of Heroes 3" with retail PIB packages of Ryzen 5000 series "Zen 3" desktop processors.
