Can H100 80GB SXM5 run Phi-4-mini-instruct?

NVIDIA · 80 GB HBM3 · 3350 GB/s bandwidth · Microsoft · 3.8B · model ctx up to 128K

Yes — the H100 80GB SXM5 (80 GB HBM3) can run Phi-4-mini-instruct. At Q4 with the default 8K context it needs ≈ 3.85 GB VRAM (weights 2.09 GB + KV cache 0.76 GB + 1 GB runtime overhead), which fits within 80 GB. Decode at Q4/8K: ≈ 561.0 tok/s (estimated, batch 1). FP16 (≈ 9.36 GB) also fits, at ≈ 154.3 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	3.47 GB	Yes	561.0 est.
Q4	8K default	3.85 GB	Yes	561.0 est.
Q4	32K	6.13 GB	Yes	561.0 est.
FP16	4K	8.98 GB	Yes	154.3 est.
FP16	8K default	9.36 GB	Yes	154.3 est.
FP16	32K	11.64 GB	Yes	154.3 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).
