Usable shared or unified memory is the main blocker for this model.
Not enough usable memory
The model needs 33.3 GB, but this setup only exposes 11.5 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, Mixtral 8x7B requires more memory than MacBook Pro M2 Pro 16GB provides.
Mixtral 8x7B (47B parameters) requires approximately 33.3 GB of memory with Q4_K_M quantization.
The recommended quantization for Mixtral 8x7B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M2 Pro 16GB, Mixtral 8x7B achieves approximately 4.5 tokens per second decode speed with a time-to-first-token of 42722ms using Q4_K_M quantization.
For coding workloads, Mixtral 8x7B on MacBook Pro M2 Pro 16GB receives a F grade with 4.5 tok/s and 4K context.
On MacBook Pro M2 Pro 16GB, Mixtral 8x7B can safely use up to 4K tokens of context. The model's official context limit is 33K, 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. MacBook Pro M2 Pro 16GB 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.
