We are thinking of buying a Dell PowerEdge R7425 servers with AMD Epyc cpus.
We are looking to do a starting server of around 32cores/64threads and these are the options.
AMD EPYC™ 7281 - 32mb L3 cache 2.7ghz
AMD EPYC™ 7301 - 64mb L3 cache + 180$ per cpu 2.7ghz
AMD EPYC™ 7351 - 64mb L3 cache + 440$ per cpu 2.9ghz
all of these are 64thread cpus when paired (so x2)
So i was thinking on does that L3 matters that much or not to justify the price because the overall ghz will be roughly the same across the board.
Any knowledge about this subject is appreciated. Thanks! Wrong place for the topic though was in hardware so if some admin can move it would be awesome!
