Fragz' verdict
The Ryzen 7 9850X3D takes the lead as the better gaming CPU, outperforming the Ryzen 9 9900X by 6.8% in overall CPU score. This edge is primarily seen in its higher single-thread performance of 0.92 Gop/s, better Supernova DX11 FPS at 131.4, and a significantly larger 96 MB L3 cache, all crucial factors for gaming frame rates. It also boasts a higher peak clock of 5602 MHz and processes more draw calls per second, while both CPUs deliver identical multi-threaded integer performance. However, the Ryzen 9 9900X, with its 12 cores and 24 threads, could be a better fit for heavy multi-tasking and workstation loads, though it's important to note the Ryzen 7 9850X3D's data comes from only one verified run, making the sample thin.

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
