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 headline score is the part's best measured run, and the measurements under it come from that same run. It shows what the part has been proven to do — not what an average rig gets out of it. 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
