Can B200 192GB SXM run Qwen3-Coder-30B-A3B-Instruct?

NVIDIA · 192 GB HBM3e · 8000 GB/s bandwidth · Alibaba · 30.5B (active 3B) · MoE · model ctx up to 128K

Yes — the B200 192GB SXM (192 GB HBM3e) can run Qwen3-Coder-30B-A3B-Instruct. At Q4 with the default 8K context it needs ≈ 18.38 GB VRAM (weights 16.78 GB + KV cache 0.6 GB + 1 GB runtime overhead), which fits within 192 GB. Decode at Q4/8K: ≈ 1697.0 tok/s (estimated, batch 1). FP16 (≈ 62.6 GB) also fits, at ≈ 466.7 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	18.08 GB	Yes	1697.0 est.
Q4	8K default	18.38 GB	Yes	1697.0 est.
Q4	32K	20.18 GB	Yes	1697.0 est.
FP16	4K	62.3 GB	Yes	466.7 est.
FP16	8K default	62.6 GB	Yes	466.7 est.
FP16	32K	64.4 GB	Yes	466.7 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).
