Fragz' verdict
The Ryzen 9 9950X3D is the clear winner in this CPU showdown, leading the 13th Gen Core i5-13600KF by 36.7% in overall CPU score. This performance gap is particularly visible in gaming-critical areas, with the Ryzen chip achieving 0.92 Gop/s in single-thread operations and 131.4 FPS in the Supernova DX11 scene, significantly outperforming the 13th Gen Core i5's 0.82 Gop/s and 49.5 FPS respectively. Stronger single-thread performance typically sets the FPS ceiling in games, while its superior multi-threaded integer performance of 14.9 Gop/s (compared to 9.3 Gop/s) is crucial for background tasks, streaming, and compiling. The Ryzen also benefits from more cores, threads, a significantly larger L3 cache of 128 MB, and nearly triple the draw calls per second. However, the data for the 13th Gen Core i5-13600KF comes from only one verified run, indicating a thin sample size that introduces uncertainty. Given the substantial performance difference, the Ryzen 9 9950X3D is the superior choice for high-performance gaming.

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
