Fragz' verdict
The Core Ultra 9 285K is the decisive winner in this CPU comparison, leading the Core Ultra X7 358H by a substantial 46.7% in overall CPU score. This dominant performance is clearly visible in its single-thread score of 0.95 Gop/s compared to the 0.78 Gop/s from the Core Ultra X7 358H, which is crucial for setting the FPS ceiling in many games. Furthermore, the Core Ultra 9 285K excels in multi-threaded tasks with 12.7 Gop/s in integer operations (vs 6.4 Gop/s), alongside a massive lead in DX11 draw calls per second and an impressive 99.8 FPS in the Supernova DX11 scene (vs 27.5 FPS). With 24 cores and 36 MB of L3 cache, it offers a significantly more robust platform for gaming and background processes compared to the Core Ultra X7 358H, despite the latter's higher peak clock. However, it's important to remember that both CPUs have only one verified run each, meaning the sample is currently 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
