Can B200 192GB SXM run gemma-4-31B-it?

NVIDIA · 192 GB HBM3e · 8000 GB/s bandwidth · Google · 30.7B · model ctx up to 256K

Yes — the B200 192GB SXM (192 GB HBM3e) can run gemma-4-31B-it. At Q4 with the default 8K context it needs ≈ 24.03 GB VRAM (weights 16.89 GB + KV cache 6.14 GB + 1 GB runtime overhead), which fits within 192 GB. Decode at Q4/8K: ≈ 165.8 tok/s (estimated, batch 1). FP16 (≈ 68.54 GB) also fits, at ≈ 45.6 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	20.96 GB	Yes	165.8 est.
Q4	8K default	24.03 GB	Yes	165.8 est.
Q4	32K	42.45 GB	Yes	165.8 est.
FP16	4K	65.47 GB	Yes	45.6 est.
FP16	8K default	68.54 GB	Yes	45.6 est.
FP16	32K	86.96 GB	Yes	45.6 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).
