Fragz' verdict
The Core Ultra 9 285K takes a decisive win over the Ryzen 7 5800X, leading by 54% in component score, though we only have one verified run for the Ultra 9, so consider that sample thin. This new chip packs significantly more cores and threads, hitting 12.7 Gop/s in integer multi-threaded operations compared to the Ryzen's 7.8 Gop/s, which is great for background tasks and streaming. Crucially for gaming, the Core Ultra 9 285K also boasts superior single-thread performance at 0.95 Gop/s versus 0.62 Gop/s, allowing it to push more draw calls per second and achieve higher framerates, like its 99.8 FPS in Supernova DX11. Its higher peak clock of 5334 MHz and larger 36 MB L3 cache further boost its capabilities. While the Ryzen 7 5800X still delivers a respectable 10075 CPU score and has many more verified runs, the Core Ultra 9 285K is clearly the more powerful CPU for raw 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
