AMD Launches 4th Gen EPYC "Genoa" Zen 4 Server Processors: 100% Performance Uplift for 50% More Cores

AMD at a special media event titled "together we advance_data centers," formally launched its 4th generation EPYC "Genoa" server processors based on the "Zen 4" microarchitecture. These processors debut an all new platform, with modern I/O connectivity that includes PCI-Express Gen 5, CXL, and DDR5 memory. The processors come in CPU core-counts of up to 96-core/192-thread. There are as many as 18 processor SKUs, differentiated not just in CPU core-counts, but also the way the the cores are spread across the up to 12 "Zen 4" chiplets (CCDs). Each chiplet features up to 8 "Zen 4" CPU cores, depending on the model; up to 32 MB of L3 cache, and is built on the 5 nm EUV process at TSMC. The CCDs talk to a centralized server I/O die (sIOD), which is built on the 6 nm process.

The processors AMD is launching today are the EPYC "Genoa" series, targeting general purpose servers, although they can be deployed in large cloud data-centers, too. To large-scale cloud providers such as AWS, Azure, and Google Cloud, AMD is readying a different class of processor, codenamed "Bergamo," which is plans to launch later. In 2023, the company will launch the "Genoa-X" line of processor for technical-compute and HPC applications, which benefit from large on-die caches, as they feature the 3D Vertical Cache technology. There will also be "Siena," a class of EPYC processors targeting the telecom and edge-computing markets, which could see an integration of more Xilinx IP.

"Despite the challenging macro environment, we grew revenue 29% year-over-year driven by increased sales of our data center, embedded and game console products. We are confident that our leadership product portfolio, strong balance sheet, and ongoing growth opportunities in our data center and embedded businesses position us well to navigate the current market dynamics."

AMD Set to Unveil its Next Generation Server Processors on the 10th of November

AMD appears to like to play coy when it comes to new product announcements, or at least the reveal of upcoming product announcements. Just as with its November 3rd event, the company has put out a miniscule teaser for its November 10th announcement of what the company is simply calling "the unveiling of our next-gen server processors" on Twitter. The event will kick off at 10 am Pacific time and it appears there will be a live stream, as AMD is inviting people to watch the event online. It's highly likely that we're talking about new EPYC parts here, as the event is called "together we advance_data centers".

AMD Rolls Out GCC Enablement for "Zen 4" Processors with Zenver4 Target, Enables AVX-512 Instructions

AMD earlier this week released basic enablement for the GNU Compiler Collections (GCC), which extend "Zen 4" microarchitecture awareness. The "basic enablement patch" for the new Zenver4 target is essentially similar to Zenver3, but with added support for the new AVX-512 instructions, namely AVX512F, AVX512DQ, AVX512IFMA, AVX512CD, AVX512BW, AVX512VL, AVX512BF16, AVX512VBMI, AVX512VBMI2, GFNI, AVX512VNNI, AVX512BITALG, and AVX512VPOPCNTDQ. Besides AVX-512, "Zen 4" is largely identical to its predecessor, architecturally, and so the enablement is rather basic. This should come just in time for software vendors to prepare for next-generation EPYC "Genoa" server processors, or even small/medium businesses building servers with Ryzen 7000-series processors.

48-Core Russian Baikal-S Processor Die Shots Appear

In December of 2021, we covered the appearance of Russia's home-grown Baikal-S processor, which has 48 cores based on Arm Cortex-A75 cores. Today, thanks to the famous chip photographer Fritzchens Fritz, we have the first die shows that show us exactly how Baikal-S SoC is structured internally and what it is made up of. Manufactured on TSMC's 16 nm process, the Baikal-S BE-S1000 design features 48 Arm Cortex-A75 cores running at a 2.0 GHz base and a 2.5 GHz boost frequency. With a TDP of 120 Watts, the design seems efficient, and the Russian company promises performance comparable to Intel Skylake Xeons or Zen1-based AMD EPYC processors. It also uses a home-grown RISC-V core for management and controlling secure boot sequences.

Below, you can see the die shots taken by Fritzchens Fritz and annotated details by Twitter user Locuza that marked the entire SoC. Besides the core clusters, we see that a slum of cache connects everything, with six 72-bit DDR4-3200 PHYs and memory controllers surrounding everything. This model features a pretty good selection of I/O for a server CPU, as there are five PCIe 4.0 x16 (4x4) interfaces, with three supporting CCIX 1.0. You can check out more pictures below and see the annotations for yourself.

AMD Collaborates with The Energy Sciences Network on Launch of its Next-Generation, High-Performance Network to Enhance Data-Intensive Science

Today AMD (NASDAQ: AMD) announced its collaboration with the Energy Sciences Network (ESnet) on the launch of ESnet6, the newest generation of the U.S. Department of Energy's (DOE's) high-performance network dedicated to science. AMD worked closely with ESnet since 2018 to integrate powerful adaptive computing for the smart and programmable network nodes of ESnet6. ESnet6's extreme scale packet monitoring system uses AMD Alveo U280 FPGA-based network-attached accelerator cards at the core network switching nodes. This will enable high-touch packet processing and help improve the accuracy of network monitoring and management to enhance performance. The programmable hardware allows for new capabilities to be added for continuous innovation in the network.

In order to customize AMD Alveo U280 2x100Gb/s accelerators as network interface cards (NIC) for ESnet6, the OpenNIC overlay - developed by AMD - was used to provide standard network-interface and host-attachment hardware, allowing novel and experimental networking functions to be implemented easily on the Alveo card. OpenNIC has since been open-sourced after being successfully used and evolved by ESnet, as well as various leading academic research groups. Also important for rapid innovation by non-hardware experts was the use of the AMD VitisNetP4 development tools for compiling the P4 packet processing language to FPGA hardware.

AMD Alveo U280 cards, using OpenNIC and VitisNetP4, are being deployed on every node of the ESnet6 network. The high-touch approach based on FPGA-accelerated processing allows every packet in the ESnet6 network to be monitored at extremely high transfer rates to enable deep insights into the behavior of the network, as well as helping to rapidly detect and correct problems and hot spots in the network. The Alveo U280 card with OpenNIC platform also supplies the adaptability to allow the continuous roll-out of new capabilities to the end user community as needs evolve over the lifetime of ESnet6.

AMD-Powered Frontier Supercomputer Faces Difficulties, Can't Operate a Day without Issues

When AMD announced that the company would deliver the world's fastest supercomputer, Frontier, the company also took a massive task to provide a machine capable of producing one ExaFLOP of total sustained ability to perform computing tasks. While the system is finally up and running, making a machine of that size run properly is challenging. In the world of High-Performance Computing, getting the hardware is only a portion of running the HPC center. In an interview with InsideHPC, Justin Whitt, program director for the Oak Ridge Leadership Computing Facility (OLCF), provided insight into what it is like to run the world's fastest supercomputer and what kinds of issues it is facing.

The Frontier system is powered by AMD EPYC 7A53s "Trento" 64-core 2.0 GHz CPUs and Instinct MI250X GPUs. Interconnecting everything is the HPE (Cray) Slingshot 64-port switch, which is responsible for sending data in and out of compute blades. The recent interview points out a rather interesting finding: exactly AMD Instinct MI250X GPUs and Slingshot interconnect cause hardware troubles for the Frontier. "It's mostly issues of scale coupled with the breadth of applications, so the issues we're encountering mostly relate to running very, very large jobs using the entire system … and getting all the hardware to work in concert to do that," says Justin Whitt. In addition to the limits of scale "The issues span lots of different categories, the GPUs are just one. A lot of challenges are focused around those, but that's not the majority of the challenges that we're seeing," he said. "It's a pretty good spread among common culprits of parts failures that have been a big part of it. I don't think that at this point that we have a lot of concern over the AMD products. We're dealing with a lot of the early-life kind of things we've seen with other machines that we've deployed, so it's nothing too out of the ordinary."

Intel Outs First Xeon Scalable "Sapphire Rapids" Benchmarks, On-package Accelerators Help Catch Up with AMD EPYC

Intel in the second day of its InnovatiON event, turned attention to its next-generation Xeon Scalable "Sapphire Rapids" server processors, and demonstrated on-package accelerators. These are fixed-function hardware components that accelerate specific kinds of popular server workloads (i.e. run them faster than a CPU core can). With these, Intel hopes to close the CPU core-count gap it has with AMD EPYC, with the upcoming "Zen 4" EPYC chips expected to launch with up to 96 cores per socket in its conventional variant, and up to 128 cores per socket in its cloud-optimized variant.

Intel's on-package accelerators include AMX (advanced matrix extensions), which accelerate recommendation-engines, natural language processing (NLP), image-recognition, etc; DLB (dynamic load-balancing), which accelerates security-gateway and load-balancing; DSA (data-streaming accelerator), which speeds up the network stack, guest OS, and migration; IAA (in-memory analysis accelerator), which speeds up big-data (Apache Hadoop), IMDB, and warehousing applications; a feature-rich implementation of the AVX-512 instruction-set for a plethora of content-creation and scientific applications; and lastly, the QAT (QuickAssist Technology), with speed-ups for data compression, OpenSSL, nginx, IPsec, etc. Unlike "Ice Lake-SP," QAT is now implemented on the processor package instead of the PCH.

Intel Expects to Lose More Market Share, to Reconsider Exiting Other Businesses

During Evercore ISI TMT conference, Intel announced that the company would continue to lose market share, with a possible bounce back in the coming years. According to the latest report, Intel's CEO Pat Gelsinger announced that he expects the company to continue to lose its market share to AMD as the competition has "too much momentum" going for it. AMD's Ryzen and EPYC processors continue to deliver power and efficiency performance figures, which drives customers towards the company. On the other hand, Intel expects a competing product, especially in the data center business with Sapphire Rapids Xeon processors, set to arrive in 2023. Pat Gelsinger noted, "Competition just has too much momentum, and we haven't executed well enough. So we expect that bottoming. The business will be growing, but we do expect that there continues to be some share losses. We're not keeping up with the overall TAM growth until we get later into '25 and '26 when we start regaining share, material share gains."

The only down years that are supposed to show a toll of solid competition are 2022 and 2023. As far as creating a bounceback, Intel targets 2025 and 2026. "Now, obviously, in 2024, we think we're competitive. 2025, we think we're back to unquestioned leadership with our transistors and process technology," noted CEO Gelsinger. Additionally, he had a say about the emerging Arm CPUs competing for the same server market share as Intel and AMD do so, stating that "Well, when we deliver the Forest product line, we deliver power performance leadership versus all Arm alternatives, as well. So now you go to a cloud service provider, and you say, 'Well, why would I go through that butt ugly, heavy software lift to an ARM architecture versus continuing on the x86 family?"

AMD EPYC "Genoa" Zen 4 Product Stack Leaked

With its recent announcement of the Ryzen 7000 desktop processors, the action now shifts to the server, with AMD preparing a wide launch of its EPYC "Genoa" and "Bergamo" processors this year. Powered by the "Zen 4" microarchitecture, and contemporary I/O that includes PCI-Express Gen 5, CXL, and DDR5, these processors dial the CPU core-counts per socket up to 96 in case of "Genoa," and up to 128 in case of "Bergamo." The EPYC "Genoa" series represents the main trunk of the company's server processor lineup, with various internal configurations targeting specific use-cases.

The 96 cores are spread twelve 5 nm 8-core CCDs, each with a high-bandwidth Infinity Fabric path to the sIOD (server I/O die), which is very likely built on the 6 nm node. Lower core-count models can be built either by lowering the CCD count (ensuring more cores/CCD), or by reducing the number of cores/CCD and keeping the CCD-count constant, to yield more bandwidth/core. The leaked product-stack table below shows several of these sub-classes of "Genoa" and "Bergamo," classified by use-cases. The leaked slide also details the nomenclature AMD is using with its new processors. The leaked roadmap also mentions the upcoming "Genoa-X" processor for HPC and cloud-compute uses, which features the 3D Vertical Cache technology.

AMD Pensando Distributed Services Card to Support VMware vSphere 8

AMD announced that the AMD Pensando Distributed Services Card, powered by the industry's most advanced data processing unit (DPU)1, will be one of the first DPU solutions to support VMware vSphere 8 available from leading server vendors including Dell Technologies, HPE and Lenovo.

As data center applications grow in scale and sophistication, the resulting workloads increase the demand on infrastructure services as well as crucial CPU resources. VMware vSphere 8 aims to reimagine IT infrastructure as a composable architecture with a goal of offloading infrastructure workloads such as networking, storage, and security from the CPU by leveraging the new vSphere Distributed Services Engine, freeing up valuable CPU cycles to be used for business functions and revenue generating applications.

AMD Confirms Optical-Shrink of Zen 4 to the 4nm Node in its Latest Roadmap

AMD in its Ryzen 7000 series launch event shared its near-future CPU architecture roadmap, in which it confirmed that the "Zen 4" microarchitecture, currently on the 5 nm foundry node, will see an optical-shrink to the 4 nm process in the near future. This doesn't necessarily indicate a new-generation CCD (CPU complex die) on 4 nm, it could even be a monolithic mobile SoC on 4 nm, or perhaps even "Zen 4c" (high core-count, low clock-speed, for cloud-compute); but it doesn't rule out the possibility of a 4 nm CCD that the company can use across both its enterprise and client processors.

The last time AMD hyphenated two foundry nodes for a single generation of the "Zen" architecture, was with the original (first-generation) "Zen," which debuted on the 14 nm node, but was optically shrunk and refined on the 12 nm node, with the company designating the evolution as "Zen+." The Ryzen 7000-series desktop processors, as well as the upcoming EPYC "Genoa" server processors, will ship with 5 nm CCDs, with AMD ticking it off in its roadmap. Chronologically placed next to it are "Zen 4" with 3D Vertical Cache (3DV Cache), and the "Zen 4c." The company is planning "Zen 4" with 3DV Cache both for its server- and desktop segments. Further down the roadmap, as we approach 2024, we see the company debut the future "Zen 5" architecture on the same 4 nm node, evolving into 3 nm on certain variants.

AMD Zen 4 EPYC CPU Benchmarked Showing a 17% Single Thread Performance Increase from Zen 3

The next-generation flagship AMD GENOA EPYC CPU has recently appeared on Geekbench 5 in a dual-socket configuration for a total of 192 cores and 384 threads. The processors were installed in an unknown Suma 65GA24 motherboard running at 3.51 GHz and paired with 768 GB of DDR5 memory. This setup achieved a single-core score of 1460 and multi-core result of 96535 which places the processor approximately 17% ahead of an equivalently clocked 128 core EPYC 7763 in single-threaded performance. The Geekbench listing also includes an OPN code of 100-000000997-01 which most likely corresponds to the flagship AMD EPYC 9664 with a max TDP of 400 W according to existing leaks.

AMD Confirms Ryzen 7000 Launch Within Q3, Radeon RX 7000 Series Within 2022

AMD in its Q2-2022 financial results call with analysts, confirmed that the company's next-generation Ryzen 7000 desktop processors based on the "Zen 4" microarchitecture will debut this quarter (i.e. Q3-2022, or before October 2022). CEO Dr Lisa Su stated "Looking ahead, we're on track to launch our all-new 5 nm Ryzen 7000 desktop processors and AM5 platforms later this quarter with leadership performance in gaming and content creation."

The company also stated that its next-generation Radeon 7000 series GPUs based on the RDNA3 graphics architecture are on-track for launch "later this year," without specifying whether it meant this quarter, which could mean launch any time before January 2023. AMD is also on course to beating Intel to the next-generation of server processors with DDR5 and PCIe Gen 5 support, with its EPYC "Genoa" 96-core processor slated for later this year, as Intel struggles with a Q1-2023 general availability timeline for its Xeon Scalable "Sapphire Rapids" processor.

AMD Announces the "Zen 5" Microarchitecture and EPYC "Turin" Processor on 4nm

AMD in its Financial Analyst Day 2022 presentation, unveiled its next-generation "Zen 5" CPU microarchitecture. The company's latest CPU microarchitecture roadmap also confirms that variants of its "Zen 4" CCDs with 3D Vertical Cache (3DV Cache) are very much in the works, and there will be variants of the EPYC "Genoa" processors with 3DV Cache, besides standard ones.

AMD stated that it completed the design goal of the current "Zen 3" architecture, by building it on both 7 nm and 6 nm nodes (the latter being the client "Rembrandt" processor). The new "Zen 4" architecture will debut on the 5 nm node (TSMC N5), and could see a similar optical shrink to the newer 4 nm node somewhere down the line, although AMD wouldn't specify whether it's on the enterprise segment, or client. The next-gen "Zen 5" architecture will debut on 4 nm, and see an optical shrink to 3 nm on some future product.

ORNL Frontier Supercomputer Officially Becomes the First Exascale Machine

Supercomputing game has been chasing various barriers over the years. This has included MegaFLOP, GigaFLOP, TeraFLOP, PetaFLOP, and now ExaFLOP computing. Today, we are witnessing for the first time an introduction of an Exascale-level machine contained at Oak Ridge National Laboratory. Called the Frontier, this system is not really new. We have known about its upcoming features for months now. What is new is the fact that it was completed and is successfully running at ORNL's facilities. Based on the HPE Cray EX235a architecture, the system uses 3rd Gen AMD EPYC 64-core processors with a 2 GHz frequency. In total, the system has 8,730,112 cores that work in conjunction with AMD Instinct MI250X GPUs.

As of today's TOP500 supercomputers list, the system is overtaking Fugaku's spot to become the fastest supercomputer on the planet. Delivering a sustained HPL (High-Performance Linpack) score of 1.102 Exaflop/s, it features a 52.23 GigaFLOPs/watt power efficiency rating. In the HPL-AI metric, dedicated to measuring the system's AI capabilities, the Frontier machine can output 6.86 exaFLOPs at reduced precisions. This alone is, of course, not a capable metric for Exascale machines as AI works with INT8/FP16/FP32 formats, while the official results are measured in FP64 double-precision form. Fugaku, the previous number one, scores about 2 ExaFLOPs in HPL-AI while delivering "only" 442 PetaFlop/s in HPL FP64 benchmarks.
