Can the AMD Radeon Pro W7900 48GB run Stable Cascade?

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

Stable Cascade on the AMD Radeon Pro W7900 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 247k 53.2-65 t/s ~2.5-3 (slow)
Q8 yes 286k 106.3-129.9 t/s ~4.9-6 (slow)
Q4 yes 304k 189.8-232 t/s ~8.8-10.7 (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 AMD Radeon Pro W7900 48GB run Stable Cascade?โ–ถ

Yes. At Q4 it generates ~189.8-232 tok/s and fits up to 304k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~8.8-10.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 304k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
