Can H200 141GB SXM5 run Magistral-Small-2509?

NVIDIA · 141 GB HBM3e · 4800 GB/s bandwidth · Mistral · 24.0B · model ctx up to 128K

Yes — the H200 141GB SXM5 (141 GB HBM3e) can run Magistral-Small-2509. At Q4 with the default 8K context it needs ≈ 19.0 GB VRAM (weights 13.2 GB + KV cache 4.8 GB + 1 GB runtime overhead), which fits within 141 GB. Decode at Q4/8K: ≈ 127.3 tok/s (estimated, batch 1). FP16 (≈ 53.8 GB) also fits, at ≈ 35.0 tok/s (estimated). 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	16.6 GB	Yes	127.3 est.
Q4	8K default	19.0 GB	Yes	127.3 est.
Q4	32K	33.4 GB	Yes	127.3 est.
FP16	4K	51.4 GB	Yes	35.0 est.
FP16	8K default	53.8 GB	Yes	35.0 est.
FP16	32K	68.2 GB	Yes	35.0 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).
