Can the AMD Radeon RX 7900 XTX run DeepSeek-R1-Distill-Qwen-1.5B?

Yes โ€” here's how fast and up to what context, with real measured numbers.

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

QuantFits?Max contextSpeedBeyond context
FP16 yes 260k 169.9-207.6 t/s ~7.1-8.7 (slow)
Q8 yes 287k 339.8-415.3 t/s ~14.2-17.3 (slow)
Q4 yes 299k 606.7-741.6 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.
