FAQ
Can the NVIDIA RTX 4070 Super run Qwen 3.5 0.8B?
Yes. The NVIDIA RTX 4070 Super's 12.0GB of VRAM is enough to run Qwen 3.5 0.8B at fp16 quantization (2.6GB required).
What's the best quantization to use?
fp16 is the highest-precision quantization that fits in your 12.0GB. It uses about 2.6GB of memory and 4.1GB 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.
