Fragz' verdict
The 13th Gen Core i9-13900K is the clear winner here, leading the Ryzen 7 7735HS with Radeon Graphics by 102.5% in its CPU score, though this data is based on only two verified runs for each processor. This massive performance gap is evident across all CPU-centric tests, with the 13th Gen Core i9-13900K showing significantly higher single-thread performance at 0.88 Gop/s compared to 0.43 Gop/s, which directly translates to a much higher FPS ceiling in games. Its multi-threaded integer performance also dwarfs the competition at 12.5 Gop/s versus 4.5 Gop/s, meaning better handling of background tasks and streaming. This power translates into 77.9 FPS in our Supernova DX11 scene, leaving the Ryzen's 17.4 FPS far behind. While the 13th Gen Core i9-13900K is a top-tier performer, ranking 7th overall, the Ryzen 7 7735HS with Radeon Graphics, ranking 65th, could still be a reasonable choice for systems where the CPU score isn't the ultimate priority.

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
