Fragz' verdict

The 13th Gen Core i9-13900K takes the overall win in this CPU comparison, outperforming the Core i5-14600KF by a solid 53.5% in its component score, though we only have two verified runs for the i9. This lead is driven by its superior raw compute, boasting a significantly higher single-thread performance at 0.88 Gop/s and multi-threaded integer performance at 12.5 Gop/s, which translates to a higher FPS ceiling in games and better handling of background tasks. The i9 also benefits from a higher peak clock of 6119 MHz, more cores, threads, and L3 cache. Interestingly, the Core i5-14600KF actually pulled ahead in our Supernova DX11 test, hitting 99.8 FPS, and delivered more draw calls per second, showing it can still pack a punch in certain scenarios. For gamers prioritizing value where those specific DX11 numbers shine, the Core i5-14600KF could still be a compelling choice, but the i9-13900K is the clear performance champion.

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
