FAQ
Can the AMD RX 7900 GRE run Qwen 3.5 4B?
Yes. The AMD RX 7900 GRE's 16.0GB of VRAM is enough to run Qwen 3.5 4B at fp16 quantization (9.0GB required).
What's the best quantization to use?
fp16 is the highest-precision quantization that fits in your 16.0GB. It uses about 9.0GB of memory and 10.5GB 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.
