AMD Threadripper 9980X vs AMD Threadripper PRO 9965WX: Comparison
Threadripper 9980X vs Threadripper PRO 9965WX: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: Threadripper 9980X 320 MB against Threadripper PRO 9965WX 152 MB, 53% in favour of Threadripper 9980X. Threadripper PRO 9965WX also leads on memory channels, 4 channels on the Threadripper 9980X versus 8 channels on the Threadripper PRO 9965WX. Core count is not the same on both, 64 cores on the Threadripper 9980X versus 24 cores on the Threadripper PRO 9965WX. There is a split on thread count as well, 128 threads on the Threadripper 9980X versus 48 threads on the Threadripper PRO 9965WX. Base clock is not the same on both, 3.2 GHz on the Threadripper 9980X versus 4.3 GHz on the Threadripper PRO 9965WX. Memory support is closer, Quad-channel ECC-capable DDR5 on the Threadripper 9980X versus 8-channel ECC DDR5 on the Threadripper PRO 9965WX.
Who each one is for
Buy the Threadripper 9980X for 3D rendering and animation professionals and engineers running CAD/CAM software, though it is not built for budget builds and pure gaming rigs. The Threadripper PRO 9965WX suits content creators mixing single- and multi-threaded work and software developers with large compile jobs, though it is the wrong buy for gaming-focused builds and users on air cooling under 240mm. Our rating of the Threadripper 9980X (9.1/10): the Threadripper 9980X 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 9965WX (8.9/10): the Threadripper PRO 9965WX is a well-balanced high-core-count chip that handles both single-threaded and parallel workloads without the premium of the top-tier models.
What Threadripper 9980X and Threadripper PRO 9965WX have in common
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
Is the ECC Support the same on the Threadripper 9980X and Threadripper PRO 9965WX?
