Can H100 80GB SXM5 run gemma-4-31B-it?

NVIDIA · 80 GB HBM3 · 3350 GB/s bandwidth · Google · 30.7B · model ctx up to 256K

Yes — the H100 80GB SXM5 (80 GB HBM3) 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 80 GB. Decode at Q4/8K: ≈ 69.4 tok/s (estimated, batch 1). FP16 (≈ 68.54 GB) also fits, at ≈ 19.1 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	69.4 est.
Q4	8K default	24.03 GB	Yes	69.4 est.
Q4	32K	42.45 GB	Yes	69.4 est.
FP16	4K	65.47 GB	Yes	19.1 est.
FP16	8K default	68.54 GB	Yes	19.1 est.
FP16	32K	86.96 GB	No	46.2 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).
