Can Mac Studio M3 Ultra 96 GB run Qwen3 8B?

96 GB unified · 819 GB/s memory bandwidth · Qwen3 8B has 8.2B parameters.

Short answer

Yes, excellent for chat and acceptable or better for every workload we test.

Best quantization for chat: 6-bit (6.4 GB of weights) on LM Studio. Generation: 45–60 tok/s, leaving about 78 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.
