Fragz' verdict
The Core Ultra 7 265K takes a decisive win over the Core i9-10900F, showing a 30.6% lead in overall CPU score. This performance gap is evident across key gaming metrics: the Ultra 7 265K hits 0.77 Gop/s in single-thread performance compared to the i9-10900F's 0.55 Gop/s, which directly translates to higher potential FPS ceilings. It also boasts a massive lead in draw calls per second (12.2 million versus 4.3 million) and more than doubles the Supernova DX11 FPS, hitting 101.9 FPS versus 36.5 FPS, indicating superior game engine handling. With more cores (20 versus 10), larger L3 cache (30 MB versus 20 MB), and a higher peak clock of 5356 MHz, the Ultra 7 265K is a significantly more capable processor for modern gaming and multi-threaded tasks like streaming. While the Core i9-10900F's single verified run suggests a thin sample, its performance is clearly outmatched, making the Core Ultra 7 265K the stronger choice for gamers looking for a substantial CPU upgrade.

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
