Can B200 192GB SXM run Qwen2.5-72B-Instruct?

NVIDIA · 192 GB HBM3e · 8000 GB/s bandwidth · Alibaba · 72.7B · model ctx up to 128K

Yes — the B200 192GB SXM (192 GB HBM3e) can run Qwen2.5-72B-Instruct. At Q4 with the default 8K context it needs ≈ 55.53 GB VRAM (weights 39.99 GB + KV cache 14.54 GB + 1 GB runtime overhead), which fits within 192 GB. Decode at Q4/8K: ≈ 70.0 tok/s (estimated, batch 1). FP16 (≈ 160.94 GB) also fits, at ≈ 19.3 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	48.26 GB	Yes	70.0 est.
Q4	8K default	55.53 GB	Yes	70.0 est.
Q4	32K	99.15 GB	Yes	70.0 est.
FP16	4K	153.67 GB	Yes	19.3 est.
FP16	8K default	160.94 GB	Yes	19.3 est.
FP16	32K	204.56 GB	No	48.5 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).
