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

RX 5600 XT FAQ

Is the RX 5600 XT still worth it in 2026?

At ≈$125 used you get 25.0 tok/s per $100 on Qwen3.5 9B, which ranks 1st of the 8 cards compared here; it is also the 4th fastest out of 7 cards with 6 GB. It runs only small models well; 7–9B only just fits.

What is the largest model the RX 5600 XT can run?

Qwen2.5 7B Instruct (7.6B) is the largest at 4-bit or better: at Q4_K_M it uses 5.8 GB of 6 GB, and runs at about 34.6 tok/s. At 3-bit, a bigger model fits too: Gemma 2 9B IT (9.2B) at IQ3_M, 5.7 GB.

Can the RX 5600 XT run Qwen3.5 4B?

Yes. Qwen3.5 4B fits at Q4_K_M, using 3.4 GB of 6 GB, and it is the best model that runs well on this card.

Can the RX 5600 XT run 14B models?

No. Qwen3 14B needs 11.9 GB at Q4, more than the 6 GB on this card.

How many tokens per second does the RX 5600 XT give?

About 53.0 tok/s on Qwen3.5 4B at Q4_K_M, with the first token after 12.1 s on a 4K-token prompt.

What power supply does the RX 5600 XT need?

Plan a 300 W PSU (2× the 150 W TDP).

Is renting cheaper than buying an RX 5600 XT?

An RTX 3080 Ti (12 GB) rents from $0.13/hr. Renting costs as much as buying after ≈1,000 hours (≈0.7 years at 4 h a day).
