Can H100 80GB SXM5 run gemma-3-1b-it?

NVIDIA · 80 GB HBM3 · 3350 GB/s bandwidth · Google · 1.0B · model ctx up to 32K

Yes — the H100 80GB SXM5 (80 GB HBM3) can run gemma-3-1b-it. At Q4 with the default 8K context it needs ≈ 1.75 GB VRAM (weights 0.55 GB + KV cache 0.2 GB + 1 GB runtime overhead), which fits within 80 GB. Decode at Q4/8K: ≈ 2131.8 tok/s (estimated, batch 1). FP16 (≈ 3.2 GB) also fits, at ≈ 586.2 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	1.65 GB	Yes	2131.8 est.
Q4	8K default	1.75 GB	Yes	2131.8 est.
Q4	32K	2.35 GB	Yes	2131.8 est.
FP16	4K	3.1 GB	Yes	586.2 est.
FP16	8K default	3.2 GB	Yes	586.2 est.
FP16	32K	3.8 GB	Yes	586.2 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).
