Can the NVIDIA H100 SXM5 80GB run GLM-2B?

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

GLM-2B on the NVIDIA H100 SXM5 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 1039k 611.4-728.6 t/s ~7.3-8.7 (slow)
Q8 yes 1070k 1222.8-1457.3 t/s ~14.6-17.4 (slow)
Q4 yes 1083k 2183.5-2602.2 t/s ~26.1-31.1 (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 GLM-2B?โ–ถ

Yes. At Q4 it generates ~2183.5-2602.2 tok/s and fits up to 1083k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~26.1-31.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1083k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
