Can I run Qwen3.6 35B-A3B on Nvidia GeForce RTX 4090 (24GB)?
No. Qwen3.6 35B-A3B needs ~24.5 GB even at Q4_K_M, but Nvidia GeForce RTX 4090 (24GB) only has ~23 GB usable.
Needs ~24.5 GB even at Q4_K_M, but only ~23 GB is usable.
That figure is at a 4k context and moves about ±15% as context length changes.
The gap is about 1.5 GB: Qwen3.6 35B-A3B needs roughly 24.5 GB at Q4_K_M and Nvidia GeForce RTX 4090 (24GB) leaves only about 23 GB usable for a model. The lightest tracked hardware that runs Qwen3.6 35B-A3B is the Nvidia GeForce RTX 5090 (32GB) at 32 GB. See Qwen3.6 35B-A3B on Nvidia GeForce RTX 5090 (32GB).

FAQ
Can Nvidia GeForce RTX 4090 (24GB) run Qwen3.6 35B-A3B?
No. Qwen3.6 35B-A3B needs ~24.5 GB even at Q4_K_M, but Nvidia GeForce RTX 4090 (24GB) only has ~23 GB usable.
How much memory does Qwen3.6 35B-A3B need?
Nvidia GeForce RTX 4090 (24GB) does not have enough memory. At Q4_K_M the weights are ~22.29 GB; with KV cache and runtime overhead, budget ~24.5 GB at a 4k context. It is a Mixture-of-Experts model (36B total / 3B active), so all experts must stay in memory; memory tracks total params, not active params.
What is the best tool to run Qwen3.6 35B-A3B on Windows?
LM Studio for a simple setup; Ollama (CUDA) for the most speed. AMD GPUs run via Vulkan/ROCm at roughly half CUDA throughput. NVIDIA is the smooth path on Windows.

Weights are measured from GGUF files; KV cache and overhead are computed, so totals can vary ~15% with context and runtime. Any tok/s is a bandwidth estimate. See methodology.
