RX 5600 XT strengths and weaknesses

Strengths

  • Runs 7–9B models: Qwen3.5 9B at 31.3 tok/s in 5.8 GB
  • Low power draw: 150 W board power; a 300 W PSU is enough

Weaknesses

  • 14B models don't fit: Qwen3 14B needs 11.9 GB at Q4 vs 6 GB here
  • Little room for context: Qwen3.5 9B uses 5.8 of 6 GB, 0.2 GB left
  • Slow prompt reading: A 4K-token prompt on Qwen3.5 4B waits 12.0 s for the first token
  • ROCm, not CUDA: No FP8 weights; MXFP4 only through llama.cpp, not vLLM

Speed per dollar and per watt

On Qwen3.5 9B (9B params) at Q4_K_M. New prices are compared with new, used with used. The last two columns are the speed you get per $100 of price and per 100 W of board power; higher is better. The RX 5600 XT has no new price, so the New view shows it at its MSRP.
