What the numbers mean
The GPU score is the graphics card's own performance — that is what we rank on. GAMING is the whole rig's score in the best PC we measured the card in, and depends on processor, memory and storage. 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
