Fragz' verdict

The Core Ultra 9 285K is the clear winner in this CPU comparison, leading the 13th Gen Core i5-13600KF by 33.3% in overall CPU score. This performance gap is evident in its superior single-thread performance of 0.95 Gop/s, which is critical for gaming frame rates, and a significantly higher Supernova DX11 FPS of 99.8. The Core Ultra 9 285K also boasts better multi-threaded integer performance and nearly twice the draw calls per second, backed by more cores, threads, and L3 cache. However, with only one verified run for each processor, these results come from a thin sample and should be viewed with some caution. While the Core Ultra 9 285K is a powerhouse, the 13th Gen Core i5-13600KF remains a respectable performer, holding rank 9 out of 57, making it a viable choice depending on a gamer's specific needs.

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
