Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 154.0 GB, but this setup only exposes 46.1 GB of usable shared or unified memory.
Move to a larger memory pool
A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.

No, Qwen 3 235B A22B requires more memory than Mac Studio M1 Ultra 64GB provides.
Qwen 3 235B A22B (235B parameters) requires approximately 154.0 GB of memory with Q4_K_M quantization.
The recommended quantization for Qwen 3 235B A22B is Q4_K_M, which balances quality and memory efficiency.
On Mac Studio M1 Ultra 64GB, Qwen 3 235B A22B achieves approximately 4.0 tokens per second decode speed with a time-to-first-token of 48043ms using Q4_K_M quantization.
For coding workloads, Qwen 3 235B A22B on Mac Studio M1 Ultra 64GB receives a F grade with 4.0 tok/s and 4K context.
On Mac Studio M1 Ultra 64GB, Qwen 3 235B A22B can safely use up to 4K tokens of context. The model's official context limit is 131K, but available memory constrains the safe maximum.
Move to a larger memory pool. A larger unified-memory SKU or a discrete high-bandwidth GPU is the cleanest way to make this model practical.
Not always. Mac Studio M1 Ultra 64GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
