AMD EPYC Genoa leak details astonishing leap over Milan for the Zen 4 5nm server CPU series: Up to 96 cores, 192 threads, and 12-channel DDR5 memory support
A leak from ExecutableFix has offered up a wealth of information about the Zen 4 AMD EPYC server chips, which are also known as Genoa. The EPYC Genoa series is expected to make an appearance in 2022, after the Zen 3 EPYC Milan range has had an opportunity to amaze the world with its processing power. EPYC Genoa will be based on the 5nm manufacturing process, and it will apparently feature up to a 96-core, 192-thread SKU.
Unsurprisingly, with all those extra cores (Milan is expected to “only” go up to 64 cores) the EPYC Genoa processor is also rumored to be coming with more chiplets. ExecutableFix has posted a mock-up of what a 96-core EPYC Genoa chip could look like with 12 chiplets for the cores and one for the I/O die (see below). Additionally, the same source has stated that EPYC Genoa will offer support for 12-channel DDR5-5200 memory (Milan = 8-channel DDR4-3200) and up to 128 PCIe 5.0 lanes – or even up to 160 in a dual-socket configuration.
It almost seems like AMD has thrown everything but the kitchen sink at the EPYC Genoa server series, which will have a default TDP of 320 W that is configurable up to a whopping 400 W. The final detail mentioned is the SP5 (LGA 6096) socket, while EPYC Naples, Rome, and Milan utilize the SP3 platform and LGA 4094 socket. Everything about EPYC Genoa appropriately sounds epic, and one can only hope this kind of likely impressive generational leap also applies to the Zen 4 desktop and mobile processor ranges.
