Yi-1.5-9B on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 22k 34.2-41.9 t/s ~1.4-1.7 (slow)
Q8 yes 90k 68.5-83.7 t/s ~2.9-3.5 (slow)
Q4 yes 119k 122.3-149.5 t/s ~5.1-6.2 (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.
