DeepSeek-R1-Distill-Qwen-1.5B on the AMD Radeon RX 6900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 147k 90.6-110.7 t/s ~7.1-8.7 (slow)
Q8 yes 175k 181.2-221.5 t/s ~14.2-17.3 (slow)
Q4 yes 187k 323.6-395.5 t/s ~25.3-30.9 (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.
