QuantFits?Max contextSpeedBeyond context
FP16 yes 91k 19.6-23.9 t/s ~0.9-1.1 (slow)
Q8 yes 176k 39.2-47.9 t/s ~1.8-2.2 (slow)
Q4 yes 213k 69.9-85.5 t/s ~3.2-4 (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.

Can the AMD Radeon Pro W7900 48GB run Jiutian?โ–ถ

Yes. At Q4 it generates ~69.9-85.5 tok/s and fits up to 213k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.2-4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 213k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
