Can RTX 5090 32GB run Mixtral-8x7B-Instruct-v0.1?

NVIDIA · 32 GB GDDR7 · 1792 GB/s bandwidth · Mistral · 46.7B (active 12.9B) · MoE · model ctx up to 32K

Yes — the RTX 5090 32GB (32 GB GDDR7) can run Mixtral-8x7B-Instruct-v0.1. At Q4 with the default 8K context it needs ≈ 29.27 GB VRAM (weights 25.69 GB + KV cache 2.58 GB + 1 GB runtime overhead), which fits within 32 GB. Decode at Q4/8K: ≈ 88.4 tok/s (estimated, batch 1). FP16 needs ≈ 96.98 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	27.98 GB	Yes	88.4 est.
Q4	8K default	29.27 GB	Yes	88.4 est.
Q4	32K	37.01 GB	No	188.8 est.
FP16	4K	95.69 GB	No	7.8 est.
FP16	8K default	96.98 GB	No	7.6 est.
FP16	32K	104.72 GB	No	6.5 est.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s means the model is far beyond this card (offload-only territory).
