So according to this Sapphire Rapid has 26 cores per socket at about 2.7Ghz. The power consumption of a server with 2 of these inside, including DDR5 and all the rest is ... 800W
EDIT:
It obviously also depends on how much RAM the system has.
The following comparison is obviously apples to oranges but IMO significant enough that I just can't not make it:
I can order a dual-socket Dell
PowerEdge 7525 with 2x Epyc 7713 (225W) with 128 cores (instead of 52 though yeah, only with 2 GHz base clock), fit it with up to and including 14 x 64GB 3200MT/s dimms, before it starts to complain that the 800W PSU is not enough.
Bear in mind the PSU definitely has a safety margin, so even with 16 such dimms it absolutely is drawing less than 800W!
If this is anywhere near accurate and goes aganst 5nm 96 core Genoa (and the 128 Core successor) ....
