Fragz' verdict
Based on a thin sample of two verified runs for each, the 13th Gen Core i9-13900K takes a strong lead in this CPU comparison, outperforming the Ryzen 7 7435HS by 56.1% in overall CPU score. This performance gap is evident across the board, with the 13th Gen Core i9-13900K showing significantly higher multi-threaded integer performance at 12.5 Gop/s compared to the Ryzen 7's 6 Gop/s, which benefits tasks like streaming or compiling. Crucially for gamers, its single-thread performance is also stronger at 0.88 Gop/s against 0.56 Gop/s, indicating a higher FPS ceiling in many titles, further supported by its 24 cores, 32 threads, 36 MB of L3 cache, and a peak clock of 6119 MHz. It also delivered 9,342,700 draw calls per second and 77.9 FPS in the Supernova DX11 scene. While the Ryzen 7 7435HS still holds a respectable 42nd place out of 93 CPUs, if top-tier CPU performance is your absolute priority, the 13th Gen Core i9-13900K is the clear winner here.

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
