What the numbers mean

The GAMING score is a geometric mean of GPU (63 %), CPU (30 %), RAM (5 %) and drive (2 %) — a weak part cannot hide behind a strong one. The drive score is a geometric mean of sequential read (1 MB blocks) and random 4K read (IOPS), measured unbuffered on a 256 MB temp file on the system drive. Only the system drive is measured. The same model can differ between rigs: PCIe generation, fill level and driver all matter. Every run is HMAC-signed in the app and scored on the server.
