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.

SilverStone introduced the XE360-SP5, an all-in-one liquid CPU cooler for AMD Socket SP5, making it fit for servers and workstations based on the EPYC "Genoa" and "Genoa-X" processors, and its upcoming Ryzen Threadripper HEDT processors, assuming AMD sticks to this socket infrastructure. The cooler features a copper water block that's optimized for the chiplet design of Socket SP5 processors, considering the hottest components (the up to twelve "Zen 4" CCDs) are toward the edges, and the central region has the relatively cooler sIOD. The block does not have an integrated pump, which makes it 1U-capable. It measures 92 mm (W) x 25 mm (H) x 118 mm (D). The block is made of nickel-plated copper, with come of its structural parts being made of aluminium.

A set of 46 cm-long coolant tubes connects the block to the 28 mm-thick 360 mm x 120 mm radiator. This radiator has an integrated pump that turns at speeds of up to 4,000 RPM. A set of three SilverStone 120 mm fans comes included, each of these takes in 4-pin PWM input, turns at speeds ranging between 600 to 2,800 RPM, with a noise level of up to 46 dBA, airflow of up to 87.72 CFM, and 3.09 mm H₂O pressure. The company didn't reveal pricing.

AMD today announced revenue for the second quarter of 2023 of $5.4 billion, gross margin of 46%, operating loss of $20 million, net income of $27 million and diluted earnings per share of $0.02. On a non-GAAP basis, gross margin was 50%, operating income was $1.1 billion, net income was $948 million and diluted earnings per share was $0.58.

The second-hand market in China is always full of gems, but we never expected to see an unreleased 5 nm 96-core EPYC 9684X Genoa-X CPU with 1152 MB of L3 cache. According to the seller, the CPU is "almost new" and in working condition.

In case you missed it earlier, AMD is working on 5 nm Genoa-X EPYC CPUs which will feature up to 96 Zen 4 cores in 5 nm with over 1 GB of L3 cache per socket. These are scheduled to release this year, optimized for technical computing and databases. AMD is also working on Siena CPUs, which should also come this year, featuring up to 64 Zen 4 cores with optimized performance-per-watt, meant for intelligent edge and telco markets.

AMD's EPYC lineup already features the new Zen 4 core designed for better performance and efficiency. However, since the release of EPYC Milan-X processors with 3D V-cache integrated into server offerings, we wondered if AMD will continue to make such SKUs for upcoming generations. According to the report from Wccftech, we have a leaked table of specifications that showcase what some seemingly top-end Genoa-X SKUs will look like. The two SKUs listed here are the "100-000000892-04" coded engineering sample and the "100-000000892-06" coded retail sample. With support for the same SP5 platform, these CPUs should be easily integrated with the existing offerings from OEM.

As far as specifications, this processor features 384 MBs of L3 cache coming from CCDs, 768 MBs of L3 cache from the 3D V-Cache stacks, and 96 MBs of L2 cache for a total of 1248 MBs in the usable cache. A 3 MB stack of L1 cache is also dedicated to instructions and primary CPU data. Compared to the regular Genoa design, this is a 260% increase in cache sizes, and compared to Milan-X, the Genoa-X design also progresses with 56% more cache. With a TDP of up to 400 Watts, configurable to 320 Watts, this CPU can boost up to 3.7 GHz. AMD EPYC Genoa-X CPUs are expected to hit the shelves in the middle of 2023.

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 in its recent interview with TechPowerUp had asserted that 3D Vertical Cache (or 3DV Cache), isn't a one-off technology and that it would be a continual part of its roadmap. In its 2022 Financial Analyst Day presentation, the company confirmed this, by announcing variants of its CPU chiplets that have 3DV Cache, extending to both the upcoming "Zen 4" microarchitecture, and the upcoming "Zen 5," which it unveiled today.

EPYC "Genoa" is codename for the upcoming line of server processors based on the "Zen 4" CPU microarchitecture, with CPU core-counts of up to 96-core/192-thread. These feature the standard "Zen 4" CCD. The company hasn't yet announced the last-level cache (L3 cache) size of the standard "Zen 4" CCD. The company will launch the EPYC "Genoa-X" processor, which much like the EPYC "Milan-X," will incorporate 3DV Cache, with a stacked L3 cache die on top of the chiplet. "Genoa-X" is slated for a 2023 debut.
