Fragz' verdict
Core Ultra 9 290HX Plus has the higher CPU score, with a 93.7 % lead over 12th Gen Core i5-12400F. Since single-thread performance usually sets the FPS ceiling in games, you will notice the advantage with 0.94 Gop/s compared to 0.66 Gop/s. You get much better results in integer all threads testing at 14.6 Gop/s versus 4.8 Gop/s, which says more about streaming, compiling and background load. When there is a lot on screen, the Core Ultra 9 290HX Plus handles 11,343,956 draw calls per second while the 12th Gen Core i5-12400F manages 10,971,232 per second. In Supernova, the Core Ultra 9 290HX Plus hits 94.6 FPS while the 12th Gen Core i5-12400F reaches 91.5 FPS. Core Ultra 9 290HX Plus is highest in every performance test we ran.

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
