QuantFits?Max contextSpeedBeyond context
FP16 yes 191k 605-739.5 t/s ~37.6-45.9 (slow)
Q8 yes 197k 1210-1478.9 t/s ~75.2-91.9 (slow)
Q4 yes 199k 2160.8-2640.9 t/s ~134.2-164 (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 RX 9070 XT run FoundationStereo?โ–ถ

Yes. At Q4 it generates ~2160.8-2640.9 tok/s and fits up to 199k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~134.2-164 tok/s.

How much context fits?โ–ถ

At Q4, up to about 199k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
