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 RAM score is a geometric mean of bandwidth and latency. Bandwidth is measured on ONE thread — a single core cannot saturate two memory channels, so the measurement cannot see channels and we claim nothing about them. Latency is a pointer chase in a buffer four times larger than L3. The score is measured on the whole configuration: a kit running below its rated speed (XMP/EXPO off) gets the score the rig actually delivered. Every run is HMAC-signed in the app and scored on the server. The full methodology is open at https://whatfps.com/metodik
