Fragz' verdict
The 13th Gen Core i9-13900K takes a commanding lead in this CPU showdown, outperforming the Ryzen 7 5700X by 58.5% in component score, though both CPUs have a thin sample size of only one or two verified runs. For gamers, the Core i9's significantly higher single-thread performance is key, shown by its 0.89 Gop/s compared to the Ryzen's 0.58 Gop/s, resulting in a strong 116.4 FPS in Supernova DX11 versus 80.9 FPS. Its 24 cores and 32 threads also drive a massive lead in multi-threaded tasks with 15 Gop/s versus 6.6 Gop/s, and a higher draw call rate of 13.9 million per second, which is critical for complex scenes and background loads. While the Ryzen 7 5700X is clearly outclassed here, its respectable 8 cores and 16 threads, alongside 80.9 Supernova FPS, still offer solid gaming performance for many titles, especially if paired with a capable graphics card.

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
