Mixtral 8x22B v0.1 — Hardware Requirements & GPU Compatibility

Chat

Mixtral-8x22B-v0.1 is Mistral AI's large sparse mixture-of-experts base model, a pretrained checkpoint with no instruction tuning and no built-in moderation, intended as the foundation for fine-tuned or instruct derivatives rather than direct chat use. It routes each token through 2 of 8 experts, giving roughly 39 billion active parameters out of about 141 billion total, so its per-token compute is far lighter than its total size at the cost of having to hold every expert in memory. Its pretraining data covers English, French, German, Spanish, and Italian. Because all experts must be resident even though only a fraction activate per token, it still needs a multi-GPU workstation even when quantized. Context length is 65,536 tokens. It is released under the Apache 2.0 license, permitting unrestricted commercial and research use, and was published in April 2024, ahead of an instruction-tuned Mixtral-8x22B-Instruct release.

Frequently Asked Questions

How much VRAM does Mixtral 8x22B v0.1 need?

Mixtral 8x22B v0.1 requires 85.1 GB of VRAM at Q4_K_M, or 282.0 GB at BF16. Full 66K context adds up to 14.6 GB (99.7 GB total).

VRAM = Weights + KV Cache + Overhead

Weights = 140.6B × 4.8 bits ÷ 8 = 84.4 GB

KV Cache + Overhead ≈ 0.7 GB (at 2K context + ~0.3 GB framework)

KV Cache + Overhead ≈ 15.3 GB (at full 66K context)

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

Mixtral 8x22B v0.1 requires at least 60.5 GB at Q2_K, 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 ~62 tok/s on AMD Instinct MI350X. Speed depends mainly on GPU memory bandwidth. Real-world results typically within ±20%.

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

Example: NVIDIA B200 → 8000 ÷ 85.1 × 0.65 = ~131 tok/s

Estimated speed at Q4_K_M (85.1 GB)

~131 tok/s
~131 tok/s
~95 tok/s

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