There is a split on memory support as well, DDR4-3200 ECC RDIMM on the Ryzen Threadripper PRO 3995WX versus DDR4, 8-Channel, Up to 3200 MT/s on the Ryzen Threadripper PRO 5965WX.
Which should you buy, Ryzen Threadripper PRO 3995WX or Ryzen Threadripper PRO 5965WX?
Take the Ryzen Threadripper PRO 3995WX for the most demanding professional workstation workloads needing genuine 64-core, 128-thread single-socket throughput. Avoid it for anyone outside extreme professional workstation use, this is specialized, expensive hardware far beyond consumer or gaming needs. Buy the Ryzen Threadripper PRO 5965WX for mainstream desktop builds and everyday productivity, though it is not the pick for extreme overclocking (unless K/X-series) and workstation-class multi-threaded workloads.
Where the two are identical
Everything else lines up. Tdp, memory channels, socket, max memory speed and pcie generation read the same on both, so those are not worth weighing.
