AMD Radeon RX 6900 XT — Benchmarks & Specs

Bottom line: how fast is the Radeon RX 6900 XT?

SpecPicks median: 96.5 tokens/sec across 4 cited single-user runs of 7-9B dense models at 4-bit (Q4) under llama.cpp (range 83.0–108 tok/s), from llama.cpp GitHub (3 runs), KnightLi llama.cpp GPU Benchmark Scoreboard. At the $2,259.99 Amazon price of the cheapest linked listing (checked 2026-10-21 04:14 UTC; prices change), that is a SpecPicks Value Index of 42.7 tok/s per $1,000. At 1440p Ultra, the Radeon RX 6900 XT averages 140 fps in Far Cry 6 with a 104 fps 1% low, per Tech4Gamers. For local LLM inference it generates 18.5 tokens/sec running Qwen2.5 14B Instruct at q4_K_M under ollama, per LocalScore.ai. In 3DMark Fire Strike it scores 31,200–50,587 points, across two published results (Notebookcheck, Tom's Hardware). It has 16 GB of VRAM, and the Qwen2.5 14B Instruct run above (14B parameters) is the largest model on file at 4-bit quantization on this card. Larger models have no sourced run on file.

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; the SpecPicks median is computed here from the runs it names, each a row in the AI table, and the per-$1,000 figure divides it by the dated listing price. SpecPicks aggregates published measurements; it does not report first-party benchmark runs.
