Mixtral 8x22B Instruct v0.1 — Hardware Requirements & GPU Compatibility
ChatFunctionsMixtral-8x22B-Instruct-v0.1 is Mistral AI's instruction-tuned chat model, fine-tuned from the Mixtral-8x22B-v0.1 base model. It is a sparse Mixture-of-Experts model with 8 experts per layer and 2 active per token, giving roughly 39.2 billion active parameters out of about 140.6 billion total, and supports function calling for agentic and tool-use workflows. Because all experts must stay in memory even though only two run per token, it needs a multi-GPU workstation or a high-memory machine even once quantized. Context length is 65,536 tokens. It is released under the Apache 2.0 license, permitting unrestricted commercial and research use. It was published in April 2024, as the instruct variant of the larger successor to Mixtral 8x7B.

Frequently Asked Questions
How much VRAM does Mixtral 8x22B Instruct v0.1 need?
Mixtral 8x22B Instruct v0.1 requires 85.2 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 ≈ 0.8 GB (at 2K context + ~0.3 GB framework)
Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
KV Cache + Overhead ≈ 15.3 GB (at full 66K context)
VRAM usage by quantization
Can NVIDIA GeForce RTX 5090 run Mixtral 8x22B Instruct v0.1?
No — Mixtral 8x22B Instruct v0.1 requires at least 39.4 GB at IQ2_XXS, which exceeds the NVIDIA GeForce RTX 5090's 32 GB of VRAM.
What's the best quantization for Mixtral 8x22B Instruct v0.1?
For Mixtral 8x22B Instruct v0.1, Q4_K_M (85.2 GB) offers the best balance of quality and VRAM usage. Q5_K_S (97.5 GB) provides better quality if you have the VRAM. The smallest option is IQ2_XXS at 39.4 GB.
VRAM requirement by quantization
★ Recommended — best balance of quality and VRAM usage.
Can I run Mixtral 8x22B Instruct v0.1 on a Mac?
Yes — Mac Studio M5 Max (48 GB) and 55 other Macs can run Mixtral 8x22B Instruct v0.1, the smallest at IQ2_XXS. Apple Silicon uses unified memory, so the model shares RAM with the system. At Q4_K_M you need at least 85.2 GB of usable unified memory (RAM minus macOS overhead), from Mac Studio (M3 Ultra, 96GB).
Can I run Mixtral 8x22B Instruct v0.1 locally?
Yes — Mixtral 8x22B Instruct v0.1 can run locally on consumer hardware. Popular tools include Ollama, LM Studio, and llama.cpp.
How fast is Mixtral 8x22B Instruct v0.1?
At Q4_K_M, Mixtral 8x22B Instruct 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 = 1000 ÷ (active GB ÷ (bandwidth GB/s × efficiency) × 1000 + layers × routing ms)
Mixture-of-Experts: just the active experts get read for each token, along with a fixed routing cost per layer.
Example: NVIDIA B200 → 23.7 GB active ÷ (8000 × 0.65) = 4.56 ms, plus 56 layers × 0.055 ms = 3.08 ms, so 1000 ÷ 7.64 ms = ~131 tok/s
Estimated speed at Q4_K_M (85.2 GB)
Real-world results typically within ±20%. Speed depends on batch size, quantization kernel, and software stack.
What's the download size of Mixtral 8x22B Instruct v0.1?
At Q4_K_M, the download is about 84.38 GB. The full-precision BF16 version is 281.26 GB. The smallest option (IQ2_XXS) is 38.67 GB.
Which GPUs can run Mixtral 8x22B Instruct v0.1?
No single consumer GPU has enough VRAM to run Mixtral 8x22B Instruct v0.1 at Q4_K_M (85.2 GB). Multi-GPU or professional hardware is required.
Which devices can run Mixtral 8x22B Instruct v0.1?
30 devices with unified memory can run Mixtral 8x22B Instruct v0.1 at Q4_K_M (85.2 GB), including ASUS Ascent GX10, Beelink GTR9 Pro (Ryzen AI Max+ 395, 128 GB), Framework Desktop (Ryzen AI Max+ 395, 128 GB), GMKtec EVO-X2 (Ryzen AI Max+ 395, 128 GB). Apple Silicon Macs use unified memory shared between CPU and GPU, making them well-suited for local LLM inference.
