Can the NVIDIA B200 run Stable Diffusion 3.5 Medium?

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

Stable Diffusion 3.5 Medium on the NVIDIA B200

QuantFits?Max contextSpeedBeyond context
FP16 yes 2596k 1168-1392 t/s ~5.8-7 (slow)
Q8 yes 2634k 2336-2784 t/s ~11.7-13.9 (slow)
Q4 yes 2651k 4171.4-4971.4 t/s ~20.9-24.9 (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 B200 run Stable Diffusion 3.5 Medium?โ–ถ

Yes. At Q4 it generates ~4171.4-4971.4 tok/s and fits up to 2651k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~20.9-24.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 2651k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
