Who each one is for
Take the Ryzen Threadripper PRO 3995WX for the most demanding professional workstation workloads needing genuine 64-core, 128-thread single-socket throughput. It is the wrong buy for anyone outside extreme professional workstation use, this is specialized, expensive hardware far beyond consumer or gaming needs. The Threadripper PRO 7955WX is the one to take for users entering workstation platforms for the first time and Multi-GPU or multi-NVMe builds needing extra PCIe lanes, though it is the wrong buy for users who need maximum core count and gaming-only builds. Our rating of the Threadripper PRO 7955WX (8.6/10): the Threadripper PRO 7955WX is the most accessible way into the Threadripper PRO platform, trading some core count for a lower price while keeping the ECC memory support and PCIe lane advantage that define the lineup.
