Can MI300X 192GB run Magistral-Small-2509?

AMD · 192 GB HBM3 · 5300 GB/s bandwidth · Mistral · 24.0B · model ctx up to 128K

Yes — the MI300X 192GB (192 GB HBM3) 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 192 GB. Decode at Q4/8K: ≈ 140.5 tok/s (estimated, batch 1). FP16 (≈ 53.8 GB) also fits, at ≈ 38.6 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	140.5 est.
Q4	8K default	19.0 GB	Yes	140.5 est.
Q4	32K	33.4 GB	Yes	140.5 est.
FP16	4K	51.4 GB	Yes	38.6 est.
FP16	8K default	53.8 GB	Yes	38.6 est.
FP16	32K	68.2 GB	Yes	38.6 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).
