Fragz' verdict
The Core Ultra 7 265K takes the lead in this CPU showdown, outperforming the Ryzen 7 9800X3D by 9.4% in overall CPU score, though we must note the Core Ultra 7 265K's score is based on a single verified run. The Core Ultra 7 265K shows its strength with 11.5 Gop/s in multi-threaded integer operations, higher draw calls per second at 11,952,062, and a slight edge in Supernova DX11 performance at 99.7 FPS, likely due to its significantly higher core count of 20 compared to the Ryzen's 8. While the single-thread performance is nearly identical between the two at 0.87 Gop/s for the Core Ultra and 0.86 Gop/s for the Ryzen, the Core Ultra's overall higher scores suggest better handling of background tasks and game engines that can leverage more threads. However, with its 96 MB of L3 cache compared to the Core Ultra's 30 MB, the Ryzen 7 9800X3D could still be a strong contender for games that heavily benefit from large amounts of cache, despite its lower overall CPU score.

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
