Qwen 3.5 Small 0.8B on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 290k 378-462 t/s ~15.8-19.3 (slow)
Q8 yes 302k 756-924 t/s ~31.5-38.5 (slow)
Q4 yes 307k 1350-1650 t/s ~56.3-68.8 (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.
