FAQ
Can the AMD RX 6900 XT run Mistral Small 3?
Yes. The AMD RX 6900 XT's 16.0GB of VRAM is enough to run Mistral Small 3 at Q4_1 quantization (15.8GB required).
What's the best quantization to use?
Q4_1 is the highest-precision quantization that fits in your 16.0GB. It uses about 15.8GB of memory and 17.3GB recommended for comfortable inference.
What if I need more headroom for context length?
KV cache memory grows with context length. The numbers above assume a baseline 2K-4K context. For long-context use (32K+), add another 2-6GB depending on the model architecture.
