Fragz' verdict
The Core Ultra 9 285K leads the Ryzen 7 9850X3D by 17.9% in overall CPU score, securing a higher rank, though both CPUs currently have only one verified run, making this a thin sample. The Core Ultra shows its strength in multi-threaded tasks, hitting 12.7 Gop/s in the integer test, significantly higher than the Ryzen's 9.4 Gop/s, and a slight edge in single-thread performance at 0.95 Gop/s. However, the Ryzen 7 9850X3D truly shines in critical gaming metrics, pushing 131.4 FPS in Supernova DX11 and an impressive 15,765,407 draw calls per second, thanks in part to its massive 96 MB L3 cache. This is a clear lead over the Core Ultra's 99.8 FPS and 11,963,538 draw calls in the same tests. For gamers prioritizing raw in-game performance and responsiveness in DX11 titles, the Ryzen 7 9850X3D appears to be the better contender, despite the Core Ultra's higher overall CPU score and multi-core power.

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
