Can Desktop PC · GeForce RTX 4090 · 64 GB RAM run Qwen3.6 35B-A3B?
24 GB VRAM + 64 GB RAM · 1008 GB/s memory bandwidth · Qwen3.6 35B-A3B has 36B parameters (3B active per token).
Short answer
Yes, excellent for chat and acceptable or better for every workload we test.
Best quantization for chat: Q4_K_M (21 GB of weights) on Ollama. Generation: 240–330 tok/s, leaving about 1.5 GB free for your other apps.
How it rates for each workload
Same model and machine, different jobs. Agents and long documents send far bigger prompts than chat, so they need much more speed and memory.
