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.

AEWIN provides a series of performant Network Appliances and Edge Server powered by single AMD Zen 4c EPYC 8004 processor codenamed Siena. The latest AMD Siena CPU is produced with 5 nm manufacturing technology to have up to 64 cores (extreme density of 2CCX/CCD) and 225 W TDP with lower energy consumption compared to EPYC SP5. Siena SP6 CPU has the best performance per watt and is with the support of rich I/O and CXL 1.1.

SCB-1945 (1U) and SCB-1947A (2U) are two performant Network Appliances supporting 12x DDR5 sockets and 4x/8x PCIe Gen 5 slots for AEWIN self-design NICs with 1G to 100G copper/fiber interfaces (with/without bypass function) or other accelerators and NVMe SSDs. Both models provide the flexibility to change 2x front panel PCIe slots to 1x PCIe x16 slot for installing off-the-shelf add-on card for additional functions required. It can support 400G NIC card installed such as NVIDIA Mellanox PCIe 5.0 NIC.

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 rolled out the new compacted Socket SP6 server platform designed for smaller servers locally deployed at the edge by organizations. With CPU core-counts of up to 64-core/128-thread, these processors are based on the "Zen 4c" microarchitecture, which comes with identical IPC and ISA to "Zen 4," but with smaller L3 cache available per core. The EPYC 8004 series targets traditional data-centers located on-site for organizations. Even if the heavy-lifting of the IT for them is performed by remote data-centers or cloud providers, organizations still need smaller edge server deployments. The EPYC 8004 series caters to a different kind of servers than the ones the lower core-count models of EPYC 9004 "Genoa" do.

With the EPYC 8004 series, AMD is debuting a new smaller CPU socket called SP6. The socket measures 58.5 mm x 75.4 mm, compared to the 76.0 mm x 80.0 mm of Socket SP5 powering EPYC 9004 "Genoa" and EPYC 97x4 "Bergamo." Socket SP5 is an LGA with a pin count of 4,844, compared to SP5, which is LGA-6096. The first line of processors for this socket, the EPYC 8004 series, are codenamed "Siena." These are very much part of the 4th Gen EPYC series, a lineage it shares with "Genoa" for data-center servers, "Genoa-X" for compute servers, and "Bergamo" for high-density cloud.

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.

EK, the leading liquid cooling gear manufacturer, launches a workstation and a 1U rack-compatible high-performance liquid cooling solution for AMD Zen 4-based EPYC server processors. Code-named "Genoa," these AMD CPUs come with up to 96 cores and 192 threads and have a TDP of up to 360W. These specifications render these processors perfect for liquid cooling, especially in a dual-socket motherboard environment.

Powerful coolers for large processors on Intel Socket LGA 4677! With the new Enterprise Solution Jet and Stream CPU coolers, Alphacool presents progressive solutions for CPU cooling in server and workstation systems.

The Alphacool ES Jet CPU Cooler is equipped with a new complex 4-nozzle technology. For the first time, it distributes water evenly over the cooler base via four nozzles incorporated into the cooler. Thereby, all cores of the high-performance processor are optimally supplied and thus effectively and precisely cooled. The organic water flow ensures a disturbance-free water flow and thus increases the cooling performance. This method makes it possible to optimally dissipate waste heat of up to 800 watts. The chrome-plated cooler base is made of copper and is ideally suited for server and workstation systems with its extremely high thermal conductivity.

AMD is launching two distinct classes of next-generation enterprise processors, the 4th Generation EPYC "Genoa" with CPU core-counts up to 96-core/192-thread; and the new EPYC "Bergamo" with a massive 128-core/256-thread compute density. Pictures of the "Genoa" MCM are already out in the wild, revealing twelve "Zen 4" CCDs built on 5 nm, and a new-generation sIOD (I/O die) that's very likely built on 6 nm. The fiberglass substrate of "Genoa" already looks crowded with twelve chiplets, making us wonder if AMD needed a larger package for "Bergamo." Turns out, it doesn't.

In its latest Corporate presentation, AMD reiterated that "Bergamo" will be based on the same SP5 (LGA-6096) package as "Genoa." This would mean that the company either made room for more CCDs, or the CCDs themselves are larger in size. AMD states that "Bergamo" CCDs are based on the "Zen 4c" microarchitecture. Details about "Zen 4c" are scarce, but from what we gather, it is a cloud-optimized variant of "Zen 4" probably with the entire ISA of "Zen 4," and power characteristics suited for high-density cloud environments. These chiplets are built on the same TSMC N5 (5 nm EUV) process as the regular "Zen 4" CCDs.

Chinese cooler manufacturer Cool Server have recently listed several upcoming coolers for the AMD Zen 4 AM5 & SP5 sockets. The manufacturer has listed 5 AM5 coolers, and 4 SP5 coolers all targeted towards the enterprise sector. The lineup includes several passive coolers which rely on case airflow while the others feature high-performance fans which can get quite noisy. The AM5 socket will be introduced with the next-generation Zen 4 Ryzen processors while the SP5 (LGA6096) socket has been prepared for the Zen 4 EPYC processors. The complete list of coolers can be found below.

AMD's next-generation EPYC enterprise processor that succeeds the upcoming 3rd Gen EYPIC "Milan," codenamed "Genoa," is expected to be the first major platform update for AMD's enterprise platforms since the 2017 debut of the "Zen" based "Naples." Implementing the latest I/O interfaces, such as DDR5 memory and PCI-Express gen 5.0, the chip will also increase CPU core counts by 50% over "Milan," according to ExecutableFix on Twitter, a reliable source with rumors from the semiconductor industry. To enable the goals of new I/O and increased core counts, AMD will transition to a new CPU socket type, the SP5. This is a 6,096-pin land grid array (LGA), and the "Genoa" MCM package on SP5 is imagined to be visibly larger than SP3-generation packages.

With the added fiberglass substrate real-estate, AMD is expected to add more CPU chiplets to the package, and ExecutableFix expects the chiplet count to be increased to 12. AMD is expected to debut the "Zen 4" microarchitecture in the enterprise space with "Genoa," with the CPU chiplets expected to be built on the 5 nm EUV silicon fabrication node. Assuming the chiplets still only pack 8 cores a piece, "Genoa" could cram up to 96 cores per socket, or up to 192 logical processors, with SMT enabled.
