Impressive results.
Look like they chosen the best 7nm silicon available at TSMC to assemble these SKUs. Basically they
have two times the cores (same clock) with only 40W more power consumption over Naples, not to mention the Zen 2 core is stronger so it draw more power than plain Zen on the same process and the
level of power hungry off die interconnection is INSANE.
A great showcase, now AMD has to prove to be able to supply the channels with Epyc. One thing
is to supply limited quantities, another one millions and millions of SKUs.
Bet an hypothetical very popular cpu ala 7742 could be rated between 280-300W to have enough silicon for customers scoring an acceptable profit.
Great show :). Now i want to see the manufacturing/financial side of the story.
