Fragz' verdict
The Core Ultra 7 265K clearly takes the win here, leading the 13th Gen Core i5-13600KF by 17.7% in overall CPU score. This performance gap is evident across multiple tests, with the Core Ultra 7 265K delivering significantly higher integer multi-threaded Gop/s (11.5 vs 9.3) and nearly doubling the draw calls per second (11,952,062 vs 5,942,599). It also shows a strong lead in the Supernova DX11 scene, hitting 99.7 FPS compared to 49.5 FPS, backed by a higher single-thread Gop/s (0.87 vs 0.82) which often dictates in-game FPS ceilings. With more cores, L3 cache, and a higher peak clock, the Core Ultra 7 265K is the stronger performer. However, it's important to note that both CPUs were measured in only one verified run, so the sample is thin.

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
