You know when you see something that seems totally overkill it makes you laugh? This is one of them. 1.4ghz speed does seem slow, but it IS an engineering sample. The EPYC 7601 32/64 runs at 2.2ghz base, so between the process shrink and tweaking, I wouldn't be surprised to see this thing at 1.8ghz base, if not higher, before retail. Makes you wonder though, with the average speeds being listed at 2.2ghz, it looks like it's able to hold its boost clocks well.
