AMD Threadripper 9970X vs AMD Threadripper PRO 9945WX: Comparison
Threadripper 9970X vs Threadripper PRO 9945WX l3 cache compared
On l3 cache the spread is 53%, Threadripper 9970X 160 MB against Threadripper PRO 9945WX 76 MB, so Threadripper 9970X takes it. Memory channels runs the same way, 4 channels on the Threadripper 9970X versus 8 channels on the Threadripper PRO 9945WX, another win for Threadripper PRO 9945WX. Base clock is not the same on both, 4.0 GHz on the Threadripper 9970X versus 4.2 GHz on the Threadripper PRO 9945WX.
Who each one is for
The Threadripper 9970X is the one to take for 3D rendering and animation professionals and engineers running CAD/CAM software, though it is the wrong buy for budget builds and pure gaming rigs. The Threadripper PRO 9945WX suits users entering workstation platforms for the first time and Multi-GPU or multi-NVMe builds needing extra PCIe lanes, though it is not built for users who need maximum core count and gaming-only builds. Our rating of the Threadripper 9970X (9.1/10): the Threadripper 9970X delivers workstation-grade multi-threaded performance with strong single-core boost, making it a serious option for professionals who outgrew mainstream desktop platforms. Our rating of the Threadripper PRO 9945WX (8.6/10): the Threadripper PRO 9945WX 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.
Where the two are identical
Everything else lines up. Boost clock, tdp, release year, core architecture and socket read the same on both, so those are not worth weighing. They match on 1 further specification as well.
Frequently asked questions
