Fragz' verdict
The Ryzen 7 5800X dominates this comparison, outperforming the Ryzen 5 6600H with Radeon Graphics by a substantial 158.5% in overall CPU score. This lead is driven by significantly higher single-thread performance at 0.62 Gop/s versus 0.28 Gop/s, directly contributing to its 66.8 FPS in Supernova (DX11) compared to 36.5 FPS for the Ryzen 5, indicating a much higher potential FPS ceiling in games. The Ryzen 7 5800X also boasts superior multi-threaded integer performance at 7.8 Gop/s, nearly double the draw calls per second, 8 cores and 16 threads, double the L3 cache at 32 MB, and a higher peak clock of 5044 MHz. It's important to note that the Ryzen 5 6600H with Radeon Graphics only has one verified run, so its data has a higher degree of uncertainty. For serious gaming performance, the Ryzen 7 5800X is the unequivocal choice.

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
