Fragz' verdict
The 13th Gen Core i9-13900K takes a commanding lead over the Ryzen 5 5500U with Radeon Graphics, outperforming it by 391.2% in CPU score, though it's important to note both have thin sample sizes with only two and one verified runs respectively. This massive performance gap is evident in its multi-threaded integer operations at 12.5 Gop/s compared to 1.5 Gop/s, and a single-thread score of 0.88 Gop/s versus 0.19 Gop/s. For gamers, this means a significantly higher FPS ceiling and smoother handling of background tasks, further highlighted by its 77.9 FPS in the Supernova DX11 test and 9,342,700 draw calls per second. The Ryzen 5 5500U, with its lower core count, threads, L3 cache, and peak clock of 1704 MHz against the i9's 6119 MHz, simply isn't in the same league for gaming performance, making it only suitable for extremely light tasks where gaming isn't 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
