Fragz' verdict
The Core Ultra 7 265K takes a decisive win over the Ryzen 5 5600X, leading by a solid 51% in overall CPU score. This advantage is clear in gaming-relevant metrics; the Core Ultra 7 265K pushes significantly more draw calls per second at 12,220,713 compared to 8,677,022, and delivers 101.9 FPS in the Supernova DX11 test against 72.3 FPS. Its superior single-thread performance of 0.77 Gop/s (vs. 0.57 Gop/s) is key for higher game FPS ceilings, while its 10 integer multi-thread Gop/s (vs. 4.9 Gop/s) and higher core/thread count (20/20 vs 6/12) will handle background tasks and streaming much better. While clearly outpaced, the Ryzen 5 5600X still offers respectable performance, especially if you're looking for a capable CPU that won't break the bank and aren't chasing the absolute highest frame rates.

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
