Can the NVIDIA H100 SXM5 80GB run Stable Diffusion (LDM-KL-8-G)?

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

Stable Diffusion (LDM-KL-8-G) on the NVIDIA H100 SXM5 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 1056k 843.3-1005 t/s ~10.1-12 (slow)
Q8 yes 1078k 1686.6-2010 t/s ~20.1-24 (slow)
Q4 yes 1088k 3011.7-3589.3 t/s ~36-42.9 (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 Stable Diffusion (LDM-KL-8-G)?โ–ถ

Yes. At Q4 it generates ~3011.7-3589.3 tok/s and fits up to 1088k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~36-42.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1088k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
