Fragz' verdict
The Ryzen 9 9950X3D secures the top spot in this comparison, outperforming the Core Ultra 9 285K by 3% in its overall CPU score. The Ryzen part shows a clear advantage in multi-threaded integer operations at 15.2 Gop/s and pushes significantly more draw calls per second, hitting 15,649,133, which translates to smoother scene loading and more on-screen action, further boosted by its massive 128 MB of L3 cache. While the Core Ultra 9 285K does manage a slightly higher single-thread 1T performance at 0.95 Gop/s, which can be critical for raw FPS ceilings in some games, its results are based on a very thin sample of just one verified run. For most gamers, the Ryzen's strong showing in DX11 Supernova FPS at 130.5 and its overall lead make it the better bet for a consistently high-performance gaming experience.

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
