Can B200 192GB SXM run NVIDIA-Nemotron-3-Super-120B-A12B-BF16?

NVIDIA · 192 GB HBM3e · 8000 GB/s bandwidth · NVIDIA · 120.0B (active 12.0B) · MoE · model ctx up to 256K

Yes — the B200 192GB SXM (192 GB HBM3e) can run NVIDIA-Nemotron-3-Super-120B-A12B-BF16. At Q4 with the default 8K context it needs ≈ 69.4 GB VRAM (weights 66.0 GB + KV cache 2.4 GB + 1 GB runtime overhead), which fits within 192 GB. Decode at Q4/8K: ≈ 424.2 tok/s (estimated, batch 1). FP16 needs ≈ 243.4 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	68.2 GB	Yes	424.2 est.
Q4	8K default	69.4 GB	Yes	424.2 est.
Q4	32K	76.6 GB	Yes	424.2 est.
FP16	4K	242.2 GB	No	209.5 est.
FP16	8K default	243.4 GB	No	207.4 est.
FP16	32K	250.6 GB	No	195.7 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).
