An AMD roadmap of unknown origin leaked to the VideoCardz website confirms the assumption that the upcoming server processors of the Epyc 7004 series with Zen 4 architecture will exceed the previous maximum of 64 cores. However, the heat loss increases significantly at the same time.
More than 64 cores for Genoa
The “AMD Embedded Product Roadmap” shown by VideoCardz, so the title, is of older origin, after all, the Epyc 7003 (Milan) introduced in March 2021 are still listed there as a “concept”. For the year 2022, an entry for Epyc 7004 (Genoa) can be seen, which grants the processors more than 64 cores (“& gt; 64”) and a TDP range between 120 watts and “280+” watts. The current Epyc 7003 do not exceed 280 watts with a maximum of 64 cores.
The unofficial information fits well with the rumor situation from February: Up to 96 cores (192 threads) and a TDP of up to 320 watts were assumed for Genoa. It is conceivable that AMD will increase the number of CPU chips from the current maximum of eight (8 × 8 = 64 cores) by 50 percent to 12 (12 × 8 = 96 cores). There is also speculation about a larger CPU package for the new SP5 socket, 12 DDR5 channels and 128 PCIe 5.0 lanes.
Epyc 7004 Genoa based on Zen-4 is to be used for the first time in the exascale supercomputer El Capitan implemented by HPE and AMD, which with around 2 ExaFLOPS should be the fastest supercomputer in the world from 2023.
This is what Genoa will look like under the hood compared to Rome/Milan. Everything in this picture is scaled 1: 1

Successor for Epyc Embedded and Ryzen Embedded
One floor below the roadmap announces a successor to the three year old Epyc Embedded 3001 at. An introduction was planned or is therefore not planned until 2023. The jump from a maximum of 16 Zen 1 cores to 32 Zen 4 cores is large in line with the period.
The Ryzen Embedded V2000, which was introduced last year, ignores the outdated roadmap in this regard. The successor Ryzen Embedded V3000 is awarded up to eight Zen 3 cores.
