Fragz' verdict
The Core Ultra 7 265K takes a decisive win here, leading the Core Ultra X7 358H by 15.2% in overall CPU score. This lead is driven by its significantly stronger multi-threaded performance, evidenced by 10 Gop/s in the integer test compared to 6.4 Gop/s, and a much higher 12.2 million draw calls per second. Gamers will notice this difference in titles that stress the CPU with many objects or complex physics, translating to a substantially higher 101.9 FPS in the Supernova DX11 scene. While the Core Ultra X7 358H does show a slightly higher peak clock and similar single-thread performance, its overall lower core count and L3 cache, combined with a thin sample size of only one verified run, make it a less competitive option for gaming rigs seeking top CPU 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
