The trouble is you can't actually scale that way. You might be able to make a 5GHz dual core that can match a 2.5GHz quad core, but nobody can make the 80GHz dual core that would be needed to match a 2.5GHz 64-core. Good luck even making a 5GHz 32-core unless you want to measure power consumption in kilowatts.
Meanwhile if all you need is single thread performance for lower core counts, that's Ryzen rather than Epyc, but it's not like they don't make that.
- wilhil 7y agoAgreed, but, not really for servers/enterprise usage which the parent thread was about... For example, I7/I9 is much cheaper and more powerful than entry level Xeons, but, you VERY rarely see them in a rackmount chassis/server. Same goes for Epyc and Ryzen.
- zrm 7y agoThe main enterprise thing you get from Xeon and not Core is ECC memory, but Ryzen does support ECC memory, and anybody can put it in a rackmount chassis. Whether or not it's common, it's available if you want it.
