AMD Ryzen Threadripper PRO 3975WX vs AMD Ryzen Threadripper PRO 5965WX: Comparison
What is the difference between Ryzen Threadripper PRO 3975WX and Ryzen Threadripper PRO 5965WX?
Boost clock is the dividing line, Ryzen Threadripper PRO 3975WX 4.2 GHz against Ryzen Threadripper PRO 5965WX Up to 4.5 GHz. Add l2 cache to that, 16 MB on the Ryzen Threadripper PRO 3975WX versus 12 MB on the Ryzen Threadripper PRO 5965WX, and the pattern holds. There is a split on release year as well, 2020 on the Ryzen Threadripper PRO 3975WX versus 2022 on the Ryzen Threadripper PRO 5965WX. Core count is not the same on both, 32 cores on the Ryzen Threadripper PRO 3975WX versus 24 cores on the Ryzen Threadripper PRO 5965WX. There is a split on thread count as well, 64 threads on the Ryzen Threadripper PRO 3975WX versus 48 threads on the Ryzen Threadripper PRO 5965WX. Base clock is not the same on both, 3.5 GHz on the Ryzen Threadripper PRO 3975WX versus 3.8 GHz on the Ryzen Threadripper PRO 5965WX. Memory support is not the same on both, DDR4-3200 ECC RDIMM on the Ryzen Threadripper PRO 3975WX versus DDR4, 8-Channel, Up to 3200 MT/s on the Ryzen Threadripper PRO 5965WX.
Who each one is for
Take the Ryzen Threadripper PRO 3975WX for professional workstation workloads needing genuine 32-core, 64-thread single-socket throughput without the top-tier 64-core price. Avoid it for anyone outside professional workstation use, this is specialized, expensive hardware far beyond consumer needs. The Ryzen Threadripper PRO 5965WX suits mainstream desktop builds and everyday productivity, though it is not built for extreme overclocking (unless K/X-series) and workstation-class multi-threaded workloads.
Where the two are identical
Where they agree, they agree completely, tdp, l3 cache, memory channels, socket and max memory speed included, so the decision does not turn on any of those. They match on 1 further specification as well.
Frequently asked questions
Is the PCIe Generation the same on the Ryzen Threadripper PRO 3975WX and Ryzen Threadripper PRO 5965WX?
It is. Both are listed at PCIe 4.0, so it is not a reason to pick one over the other.
