DeepSeek-R1-Distill-Qwen-1.5B on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 204k 141.6-173 t/s ~7.1-8.7 (slow)
Q8 yes 231k 283.1-346.1 t/s ~14.2-17.3 (slow)
Q4 yes 243k 505.6-618 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.
