Can the NVIDIA H100 SXM5 80GB run ProtGPT2?

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

ProtGPT2 on the NVIDIA H100 SXM5 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 1078k 1656.8-1974.6 t/s ~19.8-23.6 (slow)
Q8 yes 1089k 3313.7-3949.2 t/s ~39.6-47.2 (slow)
Q4 yes 1094k 5917.3-7052.1 t/s ~70.7-84.2 (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 ProtGPT2?โ–ถ

Yes. At Q4 it generates ~5917.3-7052.1 tok/s and fits up to 1094k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~70.7-84.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1094k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
