In practical terms maybe this shouldn’t be a huge story, you’d have to think not that many people are actually in the market for a sixty four core CPU for a desktop PC. However it would be remiss not to take a moment and acknowledge that cramming sixty four cores into a single CPU is a hell of a thing to be doing. It’s not the flying cars and dinosaur theme parks we might have wanted in 2020 but it is quite a milestone and it won't eat you.
Specification-wise the Threadripper 3990X comes in with the aforementioned 64/128 cores/threads running off a base clock of 2.9GHz and a stated maximum boost clock of 4.3GHz. It has a 4MB L1 cache, 32MB L2 cache and 256MB L3 cache. It has a default TDP of 280W and, yes, it is unlocked for overclocking, because why have more CPU cores than sixteen budget systems duct-taped together if you can’t push them til they squeal?
The MSRP for the 3990X is a cool $3990 US, which makes me wonder if profit margins are taking a hit to accommodate the on-the-nose pricing or if there’s a cool name surcharge in effect.
