Measured comparison

Fragz' verdict

The Core Ultra 9 285K takes a commanding lead in this CPU showdown, outperforming the Ryzen 7 7800X3D by 72.4% in overall CPU score, though both CPUs only have a single verified run. This massive advantage comes from its significantly higher single-thread performance at 0.95 Gop/s, superior draw calls per second, and a much stronger 99.8 FPS in the Supernova DX11 test, all of which are key for maximizing game frame rates. Its 12.7 Gop/s in multi-threaded integer performance also points to better handling of background tasks and streaming. While the Ryzen 7 7800X3D features a larger 96 MB L3 cache, the Core Ultra 9 285K's higher clock speed and core/thread count deliver a clear performance win across all core CPU metrics measured.

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
