Fragz' verdict
Based on our component scores, the 13th Gen Core i9-13900K is the clear winner here, leading the Ryzen 7 4800H with Radeon Graphics by 86.6%. With only two verified runs for each processor, the sample size is thin, but the 13th Gen Core i9-13900K shows superior performance in key gaming metrics. Its single-thread performance of 0.88 Gop/s significantly outpaces the Ryzen's 0.5 Gop/s, which translates to a higher potential FPS ceiling in games, and it achieves 77.9 FPS in Supernova DX11 compared to the Ryzen's 54.7 FPS. Furthermore, the 13th Gen Core i9-13900K handles 9342700 draw calls per second, far exceeding the Ryzen's 6556514, and boasts significantly more cores, threads, and L3 cache along with a higher peak clock of 6119 MHz versus 4198 MHz, contributing to its strong multi-threaded integer performance of 12.5 Gop/s compared to 4 Gop/s. While the 13th Gen Core i9-13900K is a powerhouse for high-end gaming and demanding workloads, the Ryzen 7 4800H with Radeon Graphics still offers respectable performance, especially if it's part of a more budget-friendly or power-efficient system where its integrated graphics might be a factor.

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
