Can the NVIDIA A100 SXM4 80GB run Stable Diffusion 3.5 Large?

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

Stable Diffusion 3.5 Large on the NVIDIA A100 SXM4 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 426k 91.9-109.5 t/s ~1.8-2.1 (slow)
Q8 yes 488k 183.8-219 t/s ~3.6-4.3 (slow)
Q4 yes 515k 328.1-391.1 t/s ~6.4-7.7 (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 A100 SXM4 80GB run Stable Diffusion 3.5 Large?โ–ถ

Yes. At Q4 it generates ~328.1-391.1 tok/s and fits up to 515k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~6.4-7.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 515k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
