Ryzen Threadripper PRO 3955WX vs Threadripper PRO 7945WX: which one fits your build
The Ryzen Threadripper PRO 3955WX is the one to take for mainstream desktop builds and everyday productivity, though it is not built for extreme overclocking (unless K/X-series) and workstation-class multi-threaded workloads. Buy the Threadripper PRO 7945WX 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 7945WX (8.6/10): the Threadripper PRO 7945WX 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.
