Full processor specifications and performance ratings AMD Genoa were published by Moore’s Law is Dead.
It looks like AMD is planning to release up to 18 SKUs in the EPYC 9004 series, flagship data center processors based on the Zen4 microarchitecture. The series has up to 96 cores and 192 threads and has a default maximum TDP of 360W, although they can be configured up to 400W.
The MLID leak concerns the EPYC 9004 series, divided into different categories, focusing on core performance or density optimization. The flagship SKU called EPYC 9654 is said to offer 96 cores, 360W TDP and a clock speed of up to 3,7GHz. On the other side of the spec sheet is the 8-core EPYC 9174F with 16 cores and a TDP of 320W, although some SKUs will run at an even lower 200W.
Slides published by MLID compare AMD’s Genoa series with the 3rd generation Xeon Scalable series. The said 96-core EPYC processor offers up to 2,6 times better performance than the Xeon Platinum 9380. It is also almost twice as powerful as the 64-core EPYC 7763 Milan, which is 1,4 times faster than the Xeon.
The YouTuber published a performance chart of SPECrate 2017 Integer_Base Benchmark, which shows almost all SKUs from the said line. The fastest EPYC processor (9654) scores around 1600 points, which is four times faster than the EPYC 9124 (16 cores).
AMD has not confirmed a launch date for the EPYC 9004 series, but the new processors are expected to appear on new servers later this year. The company is also set to release the Zen4c-based Bergamo series, followed by the Genoa-X series with Zen4 cores equipped with 3D-VCache. They are not part of this leak.
The Zen4 architecture will support new DDR5 memory technology (up to 4800 Mbps) and PCIe Gen5/CXL 1.1 standards. The new processors will also require new motherboards and will not be compatible with existing AMD Milan/Rome systems.
