AMD Radeon RX 6950 XT
Refreshed 6900 XT with faster GDDR6 (576 GB/s). 16 GB VRAM, slightly more compute. ROCm officially supported. ~110-145 tok/s on 7B Q4. The bandwidth bump matters for inference; at $520-620 used it competes with used 3090 12GB on raw VRAM and beats it on bandwidth.

Sub-scores sum to 451 / 1000. Headline = 451 × 0.70 (Estimated-confidence discount) = 316. This is an algorithmic performance-tier score — distinct from, and often lower than, the editorial “Our verdict” below, which weighs value and real-world fit (especially for hardware we haven’t measured yet).

Extrapolated from 576 GB/s bandwidth — 57.6 tok/s estimated. No measured benchmarks yet.
Plain-English: Comfortable at 14B and below — snappy enough for a coding agent.

The RX 6950 XT is for the operator who needs 16 GB VRAM for 13B-30B models and wants inference speed that beats a used 3090, but doesn't need CUDA-exclusive software or multi-GPU scaling. It runs 7B Q4 at 110-145 tok/s and 13B Q4 at 60-80 tok/s, thanks to 576 GB/s bandwidth. 30B Q4 models fit in VRAM and run 25-35 tok/s. What breaks: ROCm support is narrower than CUDA; some frameworks (e.g., vLLM, ExLlama) lack full ROCm optimization, and flash attention may be missing. Multi-GPU setups are harder to configure. When to pass: if the workload requires CUDA-only tools (e.g., TensorRT-LLM), or if 24 GB VRAM is needed for 34B+ models. At $520-620 used, this card offers better inference speed than a used 3090 for the same VRAM, but loses on software ecosystem breadth.
›Why this rating
Strong inference speed and 16 GB VRAM for under $600 make it a solid choice for local LLMs, but ROCm's narrower software support and lack of CUDA compatibility hold it back from a higher rating. It's a niche pick for operators who prioritize raw bandwidth and can work around ROCm limitations.
