Fragz' verdict
The Ryzen 7 9800X3D takes a commanding lead in this CPU comparison, outperforming the 11th Gen Core i5-11400 @ 2.60GHz by 69.1% in overall CPU score. This dominant performance is evident across key metrics, with the Ryzen chip delivering significantly higher single-thread performance at 0.86 Gop/s compared to 0.52 Gop/s, which often dictates maximum in-game FPS. It also boasts stronger multi-threaded raw compute at 9.2 Gop/s versus 4.5 Gop/s, alongside a higher Supernova DX11 FPS of 96.1 and 11522990 draw calls per second, crucial for handling game logic and background tasks. The Ryzen 7 9800X3D benefits from more cores (8 vs 6), threads (16 vs 12), a much larger L3 cache at 96 MB, and a higher peak clock of 5427 MHz, all contributing to its superior gaming capabilities. While the 11th Gen Core i5-11400 @ 2.60GHz remains a decent option for its rank of 19 out of 42, the Ryzen 7 9800X3D is clearly the powerhouse for serious gamers looking for top-tier CPU performance.

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
