Fragz' verdict
The Ryzen 7 9850X3D takes a commanding lead in this CPU comparison, outperforming the 13th Gen Core i5-13600KF by 13.1% in overall CPU score, though both processors have only one verified run each, so the sample is thin. The Ryzen 7 truly shines in gaming-centric workloads, delivering significantly higher performance in the Supernova DX11 scene at 131.4 FPS compared to the Core i5's 49.5 FPS, and processing far more draw calls per second. This is bolstered by its superior single-thread performance at 0.92 Gop/s and substantially larger L3 cache of 96 MB, indicating a clear advantage for games that benefit from low latency and high single-core speed. While the Core i5-13600KF still offers a respectable 9.3 Gop/s in multi-threaded integer operations and a strong rank overall, the Ryzen 7 9850X3D is the clear choice for raw gaming performance.

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
