Fragz' verdict
The Ryzen 7 9850X3D takes a commanding lead in this CPU showdown, outperforming the Core i9-9900K by 48% in overall CPU score. However, with only one verified run for each, remember the sample size is thin. The Ryzen's advantage is evident across the board, showing a higher single-thread performance of 0.92 Gop/s compared to 0.59 Gop/s for the Core i9, which directly translates to a higher FPS ceiling in games. It also pushes significantly more draw calls per second (15.7 million vs 9.2 million) and delivers a much higher 131.4 FPS in Supernova DX11, alongside a stronger multi-threaded integer score of 9.4 Gop/s, backed by its higher peak clock speed and significantly larger L3 cache. This superior performance makes the Ryzen 7 9850X3D the clear performance 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
