Can the NVIDIA A100 SXM4 80GB run Stable Cascade?

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

Stable Cascade on the NVIDIA A100 SXM4 80GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 472k 145.4-173.2 t/s ~2.9-3.4 (slow)
Q8 yes 511k 290.7-346.5 t/s ~5.7-6.8 (slow)
Q4 yes 528k 519.1-618.7 t/s ~10.2-12.1 (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 Cascade?โ–ถ

Yes. At Q4 it generates ~519.1-618.7 tok/s and fits up to 528k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~10.2-12.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 528k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
