Can the RTX 4090 run Qwen3.6 35B A3B?

Just. Qwen3.6 35B A3B at Q4_K_M needs about 22.8 GB of the RTX 4090's 24 GB, running at an estimated 238 tok/s. Keep context short and close other GPU apps.

Estimates. Needs = weights + 1.8 GB for KV cache and runtime at modest context. Speed is single-stream decode scaled from the RTX 4090's 1008 GB/s bandwidth (XiongjieDai/GPU-Benchmarks-on-LLM-Inference). Long contexts need more memory and run slower.

Frequently asked

Quick answers

Can the NVIDIA RTX 4090 run Qwen3.6 35B A3B?

Just. Qwen3.6 35B A3B at Q4_K_M needs about 22.8 GB of the RTX 4090's 24 GB, running at an estimated 238 tok/s. Keep context short and close other GPU apps.

How much VRAM does Qwen3.6 35B A3B need?

About 21 GB of weights at Q4_K_M, 39 GB at Q8_0 and 72 GB at FP16. Add roughly 1.8 GB for the KV cache and runtime at modest context lengths.

How fast is Qwen3.6 35B A3B on the RTX 4090?

Roughly 238 tokens per second at Q4_K_M (single user, llama.cpp-style decode). This is an estimate from the RTX 4090's 1008 GB/s memory bandwidth; as a mixture-of-experts model only about 3B parameters are read per token, which is why it is faster than its size suggests.
