If you are looking for the absolute best single-socket workstation performance for Linux, there has already been the Threadripper 3970X that easily outperforms the likes of the Core i9 10980XE as Intel's top-end HEDT product, but now the Threadripper 3990X is shipping. The Threadripper 3990X is AMD's first 64-core / 128-thread desktop/workstation processor and will love your multi-threaded workloads from code compilation to content creation. As shown in our benchmarks, this single CPU is indeed faster than $20k worth of Intel Xeon Platinum CPUs.
Looks like I know what I'm going to be replacing my workstations with.
Great review by Anandtech - and this is the most important for 3990X launch: you must to use Win 10 for Workstations (or Enterprise) verssion.
From our multithreaded test data, there can only be two conclusions. One is to disable SMT, as it seems to get performance uplifts in most benchmarks, given that most benchmarks don’t understand what processor groups are. However, if you absolutely have to have SMT enabled, then don’t use normal Windows 10 Pro: use Pro for Workstations (or Enterprise) instead.
Honestly as impressive this is, I hope the next generation HEDT AMD needs to up their memory channels to 8. I still see Xeon W C621 platform has better board options when it comes board PCI-E layout and 6 channels. A high end product isn't so compelling if top end of the stack is artificially constrained. Still nice to see competitive pressure as It feels good again to be a PC enthusiast after a long hiatus.
One person (finally?) grasps that workstation CPUs shouldn't be used on consumer-oriented 'normal' version OSes!
Another person compares a prosumer (of which Intel itself has an entire lineup, X299 being the current one) CPU with a server CPU so as to tell us the server CPUs have more options!
