Fragz' verdict
Core Ultra 9 290HX Plus has the higher CPU score, leading the Core Ultra X7 358H by 47.1 %. Since single-thread usually sets the FPS ceiling in games, you get better performance here with 0.94 Gop/s compared to 0.78 Gop/s. The Core Ultra X7 358H has only been measured in a single rig, so that number is less certain. You will also see much higher draw calls per second at 11,343,956 versus 3,294,083, which matters when there is a lot on screen. In Supernova, the Core Ultra 9 290HX Plus delivers 94.6 FPS while the other chip only hits 27.5 FPS. Core Ultra 9 290HX Plus is highest in every performance test we ran.
Generated November 14, 2026 from the 25 verified runs available then. The verdict is never silently rewritten — new numbers get a new verdict.
What the numbers mean
The headline score is the part's best measured run, and the measurements under it come from that same run. It shows what the part has been proven to do — not what an average rig gets out of it. 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
