Measured comparison

Fragz' verdict

The Core Ultra 7 270K Plus comes out on top in this comparison, leading the Ryzen 9 9900X by 9.6% in overall CPU score. This lead is driven by its significantly higher multi-threaded integer performance at 12.7 Gop/s, benefiting from its 24 cores. However, the Ryzen 9 9900X shows its strength in single-thread gaming metrics, achieving a higher single-thread performance of 0.89 Gop/s, more draw calls per second at 15,180,900, and a higher 126.6 FPS in Supernova DX11, which typically dictates in-game frame rates. Given the Core Ultra 7 270K Plus only has one verified run, this result should be viewed with some uncertainty. For gamers prioritizing peak single-thread performance, the Ryzen 9 9900X might still offer a snappier experience in many titles.

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
