AMD will release the Zen 4 architecture EPYC series server processor codenamed Genoa in the fourth quarter of this year, which will use the new SP5 socket (LGA 6096) and SP6 socket, and it is also AMD’s first server platform to support PCIe 5.0 and DDR5 memory.
Recently, Twitter user @yuuki_ans revealed that the specifications of the top-level EPYC 9664 in the new generation of EPYC series server processors are slightly different from the past, and the naming method of EPYC 700x has been abandoned. The EPYC 9664 has 96 cores and 192 threads, a 50% increase in core and thread count compared to top EPYC server processors based on the Zen 3 architecture.
AMD EPYC 9664 processor has a total of 12 CCDs, each CCD has 8 cores based on Zen 4 architecture, the L3 cache is 32MB, and each core has 1MB of L2 cache, adding up to a total of 96MB of L2 cache and 384MB of L3 cache. The current flagship EPYC 7773X has 32MB of L2 cache and 256MB of L3 cache, a 67% increase in the number of caches.
It is understood that the current AMD EPYC 9664 ES version displays a base clock of 2.25GHz and a boost clock of 3.8GHz, which is slightly higher than the EPYC 7773X (2.2GHz/3.5GHz). The TDP of EPYC 9664 is 400W, which is not the upper limit of the new generation SP5 platform, which is said to reach more than 700W.
