Can I run Mixtral 8x22B v0.1 on a Mac?

Mixtral 8x22B v0.1 requires at least 58.8 GB at IQ3_XS, which exceeds the unified memory of most consumer Macs. You would need a Mac Studio or Mac Pro with a high-memory configuration.

Can I run Mixtral 8x22B v0.1 locally?

Yes — Mixtral 8x22B v0.1 can run locally on consumer hardware. At Q4_K_M quantization it needs 85.1 GB of VRAM. Popular tools include Ollama, LM Studio, and llama.cpp.

How fast is Mixtral 8x22B v0.1?

At Q4_K_M, Mixtral 8x22B v0.1 can reach ~34 tok/s on AMD Instinct MI300X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

tok/s = (bandwidth GB/s ÷ model GB) × efficiency

Example: AMD Instinct MI300X5300 ÷ 85.1 × 0.55 = ~34 tok/s

Estimated speed at Q4_K_M (85.1 GB)

~34 tok/s
~21 tok/s

Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
