Users of the Chinese forum Chiphell continue to post information related to the upcoming AMD EPYC Genoa server processors. Yesterday we saw a new processor socket LGA 6096 (Socket SP5) for future chips, the first real photo of the EPYC Genoa series processor with the heat spreading cover removed today appeared. It contains 12 CCD chips.

Recall that EPYC Genoa processors will be able to offer up to 96 physical cores with support for up to 192 virtual threads. AMD is going to release several chip models in which some of the physical cores will be artificially disabled. The presence of 12 CCD blocks in the processor does not mean that it will have all 96 active cores.
The area of one CCD chiplet on the Zen 4 architecture is 72 mm2which is 8 mm2 less than the footprint of a single EPYC Milan Zen 3 CCD block. AMD seems to have had no problem placing two sets of 6 chiplets on either side of the central I/O die. However, this is not surprising, given the 37% increase in SP5 packaging area compared to SP3.

The new AMD Socket SP5 platform will support a 12-channel DDR5 RAM controller as well as a PCIe 5.0 interface. Samples of EPYC Genoa have already begun shipping to early customers, AMD said. The release of a new series of server processors should take place by the end of this year
