Radeon RX 6600 XT

Measured performance for Radeon RX 6600 XT across 1 verified WhatFPS runs. Every number is measured in our benchmark suite — not estimated, not self-reported. GPU score (the card's own performance): 4,231 on average over the best run per rig, best run 4,231 — #34 of 64 measured graphics cards. The best rig we measured it in scored 4,552 GAMING (that number reflects the whole PC, not just Radeon RX 6600 XT). Most often paired with Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz.

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 GPU score is the hardware's own performance and what we rank on. Every run is HMAC-signed in the app and scored on the server. The full methodology is open at https://whatfps.com/metodik
