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
