AMD Radeon RX 6600 XT — Benchmarks & Specs

8 GB VRAM160W TDP$379 MSRP2021

Short answer: the AMD Radeon RX 6600 XT generates a median 34.0 tokens/sec on 7-9B dense models at 4-bit (Q4) under llama.cpp, across 5 cited runs from knightli.com, llama.cpp GitHub, GitHub: ChharithOeun/llm-amd-windows and DEV Community. Its 8 GB of VRAM holds up to Gemma 2 9B at Q4_K_M with an ~8K context, by the Will-It-Run matrix's sizing (8 of 27 models fit). At the $499.00 Amazon price checked 19 h ago (prices change), that is 68.1 tok/s per $1,000, the SpecPicks Value Index. That ranks #21 of 29 GPUs on tok/s per $1,000 in the SpecPicks value table (table built 2026-10-23 10:41 UTC).

Who should buy this instead: the AMD Radeon RX 6600 XT's 8 GB puts it in the 8 GB tier of the local-LLM GPU picks by VRAM (one card per tier, each with cited tok/s). If they need more than 8 GB, start at the 12 GB pick.

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

SpecPicks median: 34.0 tokens/sec across 5 cited single-user runs of 7-9B dense models at 4-bit (Q4) under llama.cpp (range 20.4–64.5 tok/s), from knightli.com, llama.cpp GitHub, GitHub: ChharithOeun/llm-amd-windows, DEV Community (2 runs). At the $499.00 Amazon price of the cheapest linked listing (checked ; prices change), that is a SpecPicks Value Index of 68.1 tok/s per $1,000. One of those runs: llama3.1:8b at q4_K_M generates 20.9 tokens/sec under llama.cpp, per DEV Community. At 1440p Ultra, the Radeon RX 6600 XT averages 70 fps in Borderlands 3, per HWCooling.net. In 3DMark Fire Strike it scores 28,481 points, per LanOC Reviews. Its 8 GB of VRAM is the binding constraint for local inference: the llama3.1:8b run above (8B parameters) is the largest model on file at 4-bit quantization on this card.

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.

Check what fits in 8 GB: by file size at each listed quantization, 8 of the 27 open-weight model files in the SpecPicks Will-It-Run matrix load entirely into the AMD Radeon RX 6600 XT's 8 GB while keeping at least 1.5 GB reserved for an ~8K context; the largest that fits, Gemma 2 9B (a 5.8 GB Q4_K_M file per its Hugging Face listing), leaves roughly 2.2 GB free.

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 6600 XT, 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.
