AMD Radeon RX 6600S — Benchmarks & Specs

Short answer: the AMD Radeon RX 6600S generates 50.6 tokens/sec on llama2:7b (Q4_0) under llama.cpp in a single cited run, per knightli.com llama.cpp GPU Vulkan Scoreboard; there are too few comparable runs on file for a median.

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

At 1440p Ultra, the Radeon RX 6600S averages 45 fps in Red Dead Redemption 2, per CGMagazine. For local LLM inference it generates 50.6 tokens/sec running llama2:7b at Q4_0 under llama.cpp, per knightli.com llama.cpp GPU Vulkan Scoreboard. In 3DMark Solar Bay it scores 29,529 points, per Notebookcheck.

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.

Gaming Performance (reported FPS)

Average and 1% low frame rates by game, resolution, and quality preset. Bars are scaled against the fastest result on this page.

Gaming frame rates for the Radeon RX 6600S by game, resolution, and quality preset. Rows from aggregator sites are estimates, not measured runs, dated by when SpecPicks fetched them. “1% low” is the frame-time floor that determines perceived smoothness. Each row links to its original review or benchmark database.

AI Inference Performance

Tokens per second under each model + quantization. Higher = faster generation. Bars compare runs across the same model.

Local LLM inference throughput on the Radeon RX 6600S, in generated tokens per second for a single request (one user's generation speed). Higher is better; each row links to the community report or benchmark database it came from.

Synthetic Benchmarks

Higher is better. Bars are scaled within each benchmark family (multi-thread, single-thread, etc.) so you can compare like-with-like at a glance.

Synthetic benchmark scores for the Radeon RX 6600S — higher is better. Each row links to the public database the number was taken from. A benchmark listed more than once is separate published results, shown as published rather than averaged.
