Can RTX 5090 32GB run Mistral-Medium-3.5-128B?

NVIDIA · 32 GB GDDR7 · 1792 GB/s bandwidth · Mistral · 128.0B · model ctx up to 256K

No — Mistral-Medium-3.5-128B at Q4 needs ≈ 84.2 GB even at 4K context, beyond the RTX 5090 32GB's 32 GB GDDR7. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 2.8 tok/s (estimated, batch 1). FP16 needs ≈ 282.6 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	84.2 GB	No	3.7 est.
Q4	8K default	97.0 GB	No	2.8 est.
Q4	32K	173.8 GB	No	—
FP16	4K	269.8 GB	No	—
FP16	8K default	282.6 GB	No	—
FP16	32K	359.4 GB	No	—

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).
