FAQ
Can the AMD RX 7900 XT run Qwen 3.6 27B?
Yes. The AMD RX 7900 XT's 20.0GB of VRAM is enough to run Qwen 3.6 27B at Q4_K_M quantization (17.4GB required).
What's the best quantization to use?
Q4_K_M is the highest-precision quantization that fits in your 20.0GB. It uses about 17.4GB of memory and 18.9GB 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.
