AMD Threadripper 7970X vs AMD Threadripper PRO 9955WX: Comparison
Threadripper 7970X vs Threadripper PRO 9955WX l3 cache compared
L3 cache is where these two genuinely part company, Threadripper 7970X 160 MB against Threadripper PRO 9955WX 80 MB, a 50% lead for Threadripper 7970X. Memory channels runs the same way, 4 channels on the Threadripper 7970X versus 8 channels on the Threadripper PRO 9955WX, another win for Threadripper PRO 9955WX. They differ on core architecture too, Zen 4 "Storm Peak" on the Threadripper 7970X versus Zen 5 "Shimada Peak" on the Threadripper PRO 9955WX. Base clock is not the same on both, 4.0 GHz on the Threadripper 7970X versus 4.1 GHz on the Threadripper PRO 9955WX.
Threadripper 7970X vs Threadripper PRO 9955WX: which one fits your build
The Threadripper 7970X 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. Buy the Threadripper PRO 9955WX for users entering workstation platforms for the first time and Multi-GPU or multi-NVMe builds needing extra PCIe lanes, though it is not the pick for users who need maximum core count and gaming-only builds. Our rating of the Threadripper 7970X (9.1/10): the Threadripper 7970X 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 9955WX (8.6/10): the Threadripper PRO 9955WX 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.
