Bottom line: how fast is the Radeon RX 6600 XT?

At 1440p (Ultra), the Radeon RX 6600 XT averages 137 fps in Civilization VI, per Digital Trends. For local LLM inference it generates 711.0 tokens/sec running qwen3:8b at Q8_0 under llama.cpp, per LocalLLaMA. In PassMark G3D Mark it scores 16,450 pts, per PassMark. Its 8 GB of VRAM is the binding constraint for local inference: that capacity fits 7B-parameter models at Q4.

Every figure above is a row in the tables below, and each row links out to the review or public benchmark database the number was taken from. SpecPicks aggregates published measurements; it does not report first-party benchmark runs.
