Can the NVIDIA H100 SXM5 80GB run Phi-2?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Phi-2 on the NVIDIA H100 SXM5 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 1018k 452.9-539.7 t/s ~5.4-6.4 (slow)
Q8 yes 1059k 905.7-1079.4 t/s ~10.8-12.9 (slow)
Q4 yes 1077k 1617.4-1927.6 t/s ~19.3-23 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA H100 SXM5 80GB run Phi-2?โ–ถ

Yes. At Q4 it generates ~1617.4-1927.6 tok/s and fits up to 1077k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~19.3-23 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1077k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
