Following the AM5 socket leak, it appears that more data is now surfacing on social media featuring the EPYC Genoa server CPU series. 

According to ComputerBase, the details that have leaked on the AMD SP5 socket for next-generation EPYC 7004 “Genoa” server CPU series have leaked through the Gigabyte hack. The files that are surfacing today are focusing on AMD SP5 and AM5 platforms specifically, both being AMD’s first platforms for Zen4 server and consumer platforms respectively.

The screenshots from AMD documents have been posted by @KittyYYuko. There is a good chance that AMD will issue a DMCA claim on those files and those tweets might disappear soon.

The details on AMD Genoa are allegedly from documents dated July 2021, which means they are quite recent. They describe motherboard thermal and power compatibility guidelines and details on the Zen4 EPYC CPUs themselves, including the layout of the compute tiles. It is more or less confirmed at this point that EPYC 7004 series will feature up to 12 CCDs (Core Complex), each carrying up to 8 cores. This means that the top SKU in the Zen4 Genoa lineup is to future 96 cores and 192 threads. This information had leaked before and only now has it finally been confirmed.

Furthermore, it is confirmed that Genoa CPUs will support 12-channel DDR5 memory and that the top SKU will have a default 320W TDP and a maximum of 400W. The data that was shared confirms that the peak power consumption of this SKU (noted as E) may reach up to 700W for 1 ms.
