Can the NVIDIA H200 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 H200

QuantFits?Max contextSpeedBeyond context
FP16 yes 1912k 1208.3-1440 t/s ~10.1-12 (slow)
Q8 yes 1934k 2416.6-2880 t/s ~20.1-24 (slow)
Q4 yes 1944k 4315.3-5142.9 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 H200 run Stable Diffusion (LDM-KL-8-G)?โ–ถ

Yes. At Q4 it generates ~4315.3-5142.9 tok/s and fits up to 1944k 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 1944k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
