Can the NVIDIA B200 run Stable Cascade?

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

Stable Cascade on the NVIDIA B200

QuantFits?Max contextSpeedBeyond context
FP16 yes 1258k 570.3-679.7 t/s ~2.9-3.4 (slow)
Q8 yes 1297k 1140.6-1359.4 t/s ~5.7-6.8 (slow)
Q4 yes 1314k 2036.8-2427.5 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 B200 run Stable Cascade?โ–ถ

Yes. At Q4 it generates ~2036.8-2427.5 tok/s and fits up to 1314k 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 1314k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
