Can the NVIDIA H200 run Stable Diffusion XL (SDXL)?

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

Stable Diffusion XL (SDXL) on the NVIDIA H200

QuantFits?Max contextSpeedBeyond context
FP16 yes 1853k 515.3-614.1 t/s ~4.3-5.1 (slow)
Q8 yes 1905k 1030.6-1228.2 t/s ~8.6-10.2 (slow)
Q4 yes 1927k 1840.3-2193.3 t/s ~15.3-18.3 (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 XL (SDXL)?โ–ถ

Yes. At Q4 it generates ~1840.3-2193.3 tok/s and fits up to 1927k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~15.3-18.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1927k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
