Details about AMD's Zen 4 5nm EPYC server CPU series, codenamed "Genoa", have been apparently leaked. It appears core count will go right up to 96, allowing the potential of 192-thread processing. Along with that, the incredibly powerful EPYC Genoa chips will support 12-channel DDR5 and up to 128 PCIe 5.0 lanes.

Any other details?
Optane DIMM support?
AVX512?
12 chiplets with 8 cores each...
Or 8 chiplets with 12 cores each.

The leaker reiterated that it was 8-core chiplets. I'd like to see 12-core. 8-core chiplet yields are high on 7nm so many good cores get disabled.
192 threads? maybe 182?
How much IPC improvement % versus Zen 3?
