"The AMD EPYC 4004 CPUs fill an important market gap, providing cost-optimized solutions with enterprise-grade dependability, scalability and security in cost-optimized system configurations that make sense for smaller businesses and dedicated hosters."

AMD today introduced the EPYC 4004 line of server processors in the Socket AM5 package. These chips come with up to 16 "Zen 4" CPU cores, a 2-channel DDR5 memory interface, and a 28-lane PCIe Gen 5 I/O, and are meant to power small-business servers, as well as cater to the dedicated web-server hosting business that generally attracts client-segment processors. This is the exact segment of market that Intel addresses with its Xeon E-2400 series processors in the LGA1700 package. The EPYC 4004 series offers a superior support and warranty regime compared to client-segment processors, besides ECC memory support, and AMD Secure Processor, and all of the security features you get with Ryzen PRO 7000 series processors for commercial desktops.

AMD's offer over the Xeon E-2400 series is its CPU core count of up to 16, which lets you fully utilize the 16-core limit of the Windows 2022 Server base license. The EPYC 4004 series is functionally the same processor as the Ryzen 7000 "Raphael" except for its ECC memory support. This chip features up to two 5 nm "Zen 4" CCDs with up to 8 cores, each; and an I/O die that puts out two DDR5 memory channels, and 28 PCIe Gen 5 lanes. Besides today's processor launch, several server motherboard vendors are announcing Socket AM5 server boards that are rackmount-friendly, and with server-relevant features.

The 63rd edition of the TOP500 reveals that Frontier has once again claimed the top spot, despite no longer being the only exascale machine on the list. Additionally, a new system has found its way into the Top 10.

The Frontier system at Oak Ridge National Laboratory in Tennessee, USA remains the most powerful system on the list with an HPL score of 1.206 EFlop/s. The system has a total of 8,699,904 combined CPU and GPU cores, an HPE Cray EX architecture that combines 3rd Gen AMD EPYC CPUs optimized for HPC and AI with AMD Instinct MI250X accelerators, and it relies on Cray's Slingshot 11 network for data transfer. On top of that, this machine has an impressive power efficiency rating of 52.93 GFlops/Watt - putting Frontier at the No. 13 spot on the GREEN500.

AMD has reached a significant milestone, capturing a record-high share of the X86 CPU market in the first quarter of 2024, according to the latest report from Mercury Research. This achievement marks a significant step forward for the chipmaker in its long battle against rival Intel's dominance in the crucial computer processor space. The surge was fueled by strong demand for AMD's Ryzen and EPYC processors across consumer and enterprise markets. The Ryzen lineup's compelling price-to-performance ratio has struck a chord with gamers, content creators, and businesses seeking cost-effective computing power without sacrificing capabilities. It secured AMD's 23.9% share, an increase from the previous Q4 of 2023, which has seen a 19.8% market share.

The company has also made major inroads on the data center front with its EPYC server CPUs. AMD's ability to supply capable yet affordable processors has enabled cloud providers and enterprises to scale operations on AMD's platform. Several leading tech giants have embraced EPYC, contributing to AMD's surging server market footprint. Now, it is at 23.6%, a significant increase over the past few years, whereas AMD was just above 10% four years ago in 2020. AMD lost some share to Intel on the mobile PC front due to the Meteor Lake ramp, but it managed to gain a small percentage of the market share of client PCs. As AMD rides the momentum into the second half of 2024, all eyes will be on whether the chipmaker can sustain this trajectory and potentially claim an even larger slice of the x86 CPU pie from Intel in the coming quarters.Below, you can see additional graphs of mobile PC and client PC market share.

Micron Technology, Inc. (Nasdaq: MU), today announced it is leading the industry by validating and shipping its high-capacity monolithic 32Gb DRAM die-based 128 GB DDR5 RDIMM memory in speeds up to 5,600 MT/s on all leading server platforms. Powered by Micron's industry-leading 1β (1-beta) technology, the 128 GB DDR5 RDIMM memory delivers more than 45% improved bit density, up to 22% improved energy efficiency and up to 16% lower latency over competitive 3DS through-silicon via (TSV) products.

Micron's collaboration with industry leaders and customers has yielded broad adoption of these new high-performance, large-capacity modules across high-volume server CPUs. These high-speed memory modules were engineered to meet the performance needs of a wide range of mission-critical applications in data centers, including artificial intelligence (AI) and machine learning (ML), high-performance computing (HPC), in-memory databases (IMDBs) and efficient processing for multithreaded, multicore count general compute workloads. Micron's 128 GB DDR5 RDIMM memory will be supported by a robust ecosystem including AMD, Hewlett Packard Enterprise (HPE), Intel, Supermicro, along with many others.

AMD is readying a new line of EPYC branded server processors in the Socket AM5 package, VideoCardz reports. The new processor lineup is being built to target two distinct classes of customers—small business servers, and data-centers selling small-size dedicated servers that were otherwise having to offer Ryzen chips. Intel currently has the Xeon E-2400 series "Raptor Lake-E" processors in the Socket LGA1700 package to target these exact kinds of customers. The EPYC 4004 series will be based on the same "Raphael" package as the Ryzen 7000 series, and will be a step up from the Ryzen PRO 7000 series. What sets the Ryzen PRO 7000 apart from the EPYC 4004 series are the target markets. The Ryzen PRO series target commercial desktops. Perhaps the biggest differentiator between EPYC 4004 and Ryzen PRO 7000 series is the support and warranty AMD provides to its server processors.

The "Raphael" package gives the EPYC 4004 series CPU core counts ranging between 6 and 16. These CPU cores are based on the "Zen 4" microarchitecture. The memory controllers in the I/O die will probably be reconfigured to support server memory densities, besides ECC support like on the Ryzen PRO 7000 series. There's even talk of variants with 3D V-cache, although it remains to be seen if the 12-core and 16-core variants are similar to the 7900X3D and 7950X3D, where only one of the two CCDs has 3D V-cache; or if they're the chip we all dreamed about—a "Raphael" with both CCDs featuring 3D V-cache. There are already Socket AM5 motherboards by companies such as Advantech, which are server-grade, with server-relevant I/O, like the one pictured below, and so the ecosystem for EPYC 4004 series already exists, along with upgrade headroom for future generations.

MSI, a leading global server provider, is showcasing its latest GPU servers powered by AMD processors at the 2024 NAB Show, Booth #SL9137 in the Las Vegas Convention Center from April 14-17.

AMD's next-gen EPYC Zen 5 processor family seems to be nearing launch status—late last week, momomo_us uncovered an unnamed motherboard's datasheet; this particular model will accommodate a single 9000-series CPU—with a maximum 400 W TDP—via an SP5 socket. 500 W and 600 W limits have been divulged (via leaks) in the past, so the 400 W spec could be an error or a: "legitimate compatibility issue with the motherboard, though 400 Watts would be in character with high-end Zen 4 SP5 motherboards," according to Tom's Hardware analysis.

AMD's current-gen "Zen 4" based EPYC "Genoa" processor family—sporting up to 96-cores/192-threads—is somewhat limited by its DDR5 support transfer rates of up to 4800 MT/s. The latest leak suggests that "Turin" is upgraded quite nicely in this area—when compared to predecessors—the SP5 board specs indicate DDR5 speeds of up to 6000 MT/s with 4 TB of RAM. December 2023 reports pointed to "Zen 5c" variants featuring (max.) 192-core/384-thread configurations, while larger "Zen 5" models are believed to be "modestly" specced with up to 128-cores and 256-threads. AMD has not settled on an official release date for its EPYC "Turin" 9000-series processors, but a loose launch window is expected "later in 2024" based on timeframes presented within product roadmaps.

On February 26, 2024, AMD received new research related to an industry-wide DRAM issue documented in "ZENHAMMER: Rowhammering Attacks on AMD Zen-based Platforms" from researchers at ETH Zurich. The research demonstrates performing Rowhammer attacks on DDR4 and DDR5 memory using AMD "Zen" platforms. Given the history around Rowhammer, the researchers do not consider these rowhammering attacks to be a new issue.

Mitigation
AMD continues to assess the researchers' claim of demonstrating Rowhammer bit flips on a DDR5 device for the first time. AMD will provide an update upon completion of its assessment.

The TinyBox AI server system attracted plenty of media attention last week—its creator, George Hotz, decided to build with AMD RDNA 3.0 GPU hardware rather than the expected/traditional choice of CDNA 3.0. Tiny Corp. is a startup firm dealing in neural network frameworks—they currently "write and maintain tinygrad." Hotz & Co. are in the process of assembling rack-mounted 12U TinyBox systems for customers—an individual server houses an AMD EPYC 7532 processor and six XFX Speedster MERC310 Radeon RX 7900 XTX graphics cards. The Tiny Corp. social media account has engaged in numerous NVIDIA vs. AMD AI hardware debates/tirades—Hotz appears to favor the latter, as evidenced in his latest choice of components. ROCm support on Team Red AI Instinct accelerators is fairly mature at this point in time, but a much newer prospect on gaming-oriented graphics cards.

Tiny Corporation's unusual leveraging of Radeon RX 7900 XTX GPUs in a data center configuration has already hit a developmental roadblock. Yesterday, the company's social media account expressed driver-related frustrations in a public forum: "If AMD open sources their firmware, I'll fix their LLVM spilling bug and write a fuzzer for HSA. Otherwise, it's not worth putting tons of effort into fixing bugs on a platform you don't own." Hotz's latest complaint was taken onboard by AMD's top brass—Dr. Lisa Su responded with the following message: "Thanks for the collaboration and feedback. We are all in to get you a good solution. Team is on it." Her software engineers—within a few hours—managed to fling out a set of fixes in Tiny Corporation's direction. Hotz appreciated the quick turnaround, and proceeded to run a model without encountering major stability issues: "AMD sent me an updated set of firmware blobs to try. They are responsive, and there have been big strides in the driver in the last year. It will be good! This training run is almost 5 hours in, hasn't crashed yet." Tiny Corp. drummed up speculation about AMD open sourcing GPU MES firmware—Hotz disclosed that he will be talking (on the phone) to Team Red leadership.

AMD released its latest PMC (power management controller) driver patches for the Linux kernel, which reference a yet unreleased "Family 1Ah" processors. Phoronix believes this is the first reference to AMD's next generation "Zen 5" microarchitecture in the PMC driver. We've already seen AMD EPYC "Turin" server processors based on "Zen 5" in the flesh, and it's likely that AMD is handing these out to some of its biggest data-center customers for testing and evaluation, before giving them some final touches and green-lighting mass-production in 2024. The patches themselves are barely two new lines of code, and talk about a new sleep state called "s2idle." This is a software-defined system sleep state. The EPYC "Turin" processor comes in two packages, one with up to 128 "Zen 5" cores, and another with up to 192 "Zen 5c" cores for cloud applications.

AMD's upcoming server processor, the 5th Gen EPYC "Turin," has been pictured as an engineering sample is probably being evaluated by the company's data-center or cloud customers. The processor has a mammoth core-count of 192-core/384-thread in its high-density cloud-focused variant that uses "Zen 5c" CPU cores. Its regular version that uses larger "Zen 5" cores that can sustain higher clock speeds, also comes with a fairly high core-count of 128-core/256-thread, up from the 96-core/192-thread of the "Zen 4" based EPYC "Genoa."

The EPYC "Turin" server processor based on "Zen 5" comes with an updated sIOD (server I/O die), surrounded by as many as 16 CCDs (CPU complex dies). AMD is expected to build these CCDs on the TSMC N4P foundry node, which is a more advanced version of the TSMC N4 node the company currently uses for its "Phoenix" client processors, and the TSMC N5 node it uses for its "Zen 4" CCD. TSMC claims that the N4P node offers an up to 22% improvement in power efficiency over N5, as well as a 6% increase in transistor density. Each of the "Zen 5" CCDs is confirmed to have 8 CPU cores sharing 32 MB L3 cache memory. A total of 16 such CCDs add up to the processor's 128-core/256-thread number. The high-density "Turin" meant for cloud data-centers, is a whole different beast.

Yesterday, Intel unveiled its latest Xeon data center processors, codenamed Emerald Rapids, delivering the new Xeon Platinum 8592+ flagship SKU with 64 cores and 128 threads. Packed into its fresh silicon, Intel promises boosted performance and reduced power hunger. The comprehensive tech benchmarking website Phoronix essentially confirms Intel's pitch. Testing production servers running the new 8592+ showed solid gains over prior Intel models, let alone older generations still commonplace in data centers. On average, upgrading to the 8592+ increased single-socket server performance by around 23.5% compared to the previous generation configs of Sapphire Rapid, Xeon Platinum 8490H. The dual-socket configuration records a 17% boost in performance.

However, Intel is not in the data center market by itself. AMD's 64-core offering that Xeon Platinum 8592+ is competing with is AMD EPYC 9554. The Emerald Rapids chip is faster by about 2.3%. However, AMD's lineup doesn't stop at only 64 cores. AMD's Genoa and Genoa-X with 3D V-cache top out at 96 cores, while Bergamo goes up to 128 cores. On the power consumption front, the Xeon Platinum 8592+ was pulling about 289 Watts compared to the Xeon Platinum 8490H average of 306 Watts. At peak, the Xeon Platinum 8592+ CPU managed to hit 434 Watts compared to the Xeon Platinum 8490H peak of 469 Watts. This aligns with Intel's claims of enhanced efficiency. However, compared to the 64-core counterpart from AMD, the EPYC 9554 had an average power consumption of 227 Watts and a recorded peak of 369 Watts.

Intel's upcoming Sierra Forest Xeon server chip has debuted on Geekbench 6, showcasing its potential in multi-core performance. Slated for release in the first half of 2024, Sierra Forest is equipped with up to 288 Efficiency cores, positioning it to compete with AMD's Zen 4c Bergamo server CPUs and other ARM-based server chips like those from Ampere for the favor of cloud service providers (CSP). In the Geekbench 6 benchmark, a dual-socket configuration featuring two 144-core Sierra Forest CPUs was tested. The benchmark revealed a notable multi-core score of 7,770, surpassing most dual-socket systems powered by Intel's high-end Xeon Platinum 8480+, which typically scores between 6,500 and 7,500. However, Sierra Forest's single-core score of 855 points was considerably lower, not even reaching half of that of the 8480+, which manages 1,897 points.

The difference in single-core performance is a matter of choice, as Sierra Forest uses Crestmont-derived Sierra Glen E-cores, which are more power and area-efficient, unlike the Golden Cove P-cores in the Sapphire Rapids-based 8480+. This design choice is particularly advantageous for server environments where high-core counts are crucial, as CSPs usually partition their instances by the number of CPU cores. However, compared to AMD's Bergamo CPUs, which use Zen 4c cores, Sierra Forest lacks pure computing performance, especially in multi-core. The Sierra Forest lacks hyperthreading, while Bergaamo offers SMT with 256 threads on the 128-core SKU. Comparing the Geekbench 6 scores to AMD Bergamo EPYC 9754 and Sierra Forest results look a lot less impressive. Bergamo scored 1,597 points in single-core, almost double that of Sierra Forest, and 16,455 points in the multi-core benchmarks, which is more than double. This is a significant advantage of the Zen 4c core, which cuts down on caches instead of being an entirely different core, as Intel does with its P and E-cores. However, these are just preliminary numbers; we must wait for real-world benchmarks to see the actual performance.

Supermicro, Inc., a Total IT Solution Manufacturer for AI, Cloud, Storage, and 5G/Edge, is announcing three new additions to its AMD-based H13 generation of GPU Servers, optimized to deliver leading-edge performance and efficiency, powered by the new AMD Instinct MI300 Series accelerators.

Researchers at Graz University of Technology and the Helmholtz Center for Information Security have released their paper on CacheWarp—the latest vulnerability affecting some of the prior generation AMD EPYC CPUs. Titled CVE-2023-20592, the exploit targets first-generation EPYC Naples, second-generation EPYC Rome, and third-generation EPYC Milan. CacheWarp operates by exploiting a vulnerability in AMD's Secure Encrypted Virtualization (SEV) technology, specifically targeting the SEV-ES (Encrypted State) and SEV-SNP (Secure Nested Paging) versions. The attack is a software-based fault injection technique that manipulates the cache memory of a virtual machine (VM) running under SEV. It cleverly forces modified cache lines of the guest VM to revert to their previous state. This action circumvents the integrity checks that SEV-SNP is designed to enforce, allowing the attacker to inject faults without being detected.

Unlike attacks that rely on specific guest VM vulnerabilities, CacheWarp is more versatile and dangerous because it does not depend on the characteristics of the targeted VM. It exploits the underlying architectural weaknesses of AMD SEV, making it a broad threat to systems relying on this technology for security. The CacheWarp attack can bypass robust security measures like encrypted virtualization, posing a significant risk to data confidentiality and integrity in secure computing environments. AMD has issued an update for EPYC Milan with a hot-loadable microcode patch and updated the firmware image without any expected performance degradation. And for the remaining generations, AMD states that no mitigation is available for the first or second generations of EPYC processor (Naples and Rome) since the SEV and SEV-ES features are not designed to protect guest VM memory integrity, and the SEV-SNP is not available.
