Fragz' verdict
The Ryzen 9 9950X3D is the clear winner in this comparison, outperforming the Ryzen 7 5800X by a significant 57.9% in overall CPU score and securing its position as rank 1 out of 57 measured CPUs. This lead translates directly into gaming performance, with the Ryzen 9 9950X3D hitting 131.4 FPS in the Supernova DX11 scene, nearly double the Ryzen 7 5800X's 66.8 FPS, and processing almost twice as many draw calls per second. Its superior single-thread performance of 0.92 Gop/s, compared to 0.62 Gop/s, and almost doubled multi-threaded integer performance (14.9 Gop/s vs 7.8 Gop/s), alongside its 16 cores, 32 threads, and a massive 128 MB of L3 cache, provides a substantial boost for high frame rates and smoother gameplay. However, for gamers not chasing the absolute peak performance and mindful of budget, the Ryzen 7 5800X still offers a solid experience with its 8 cores and 16 threads, making it a capable choice for many titles.

What the numbers mean
The CPU score is the processor's own performance — that is what we rank on. GAMING is the whole rig's score in the best PC we measured the processor in, and leans heavily on the graphics card. A strong processor in a weak PC gets a low GAMING score without being worse. We show both and never mix them.
All numbers come from our benchmark suite: four hand-built 3D scenes written directly against the graphics APIs in Rust, the same load on every PC. The methodology is open at https://whatfps.com/metodik
