RX 6750 XT strengths and weaknesses

Strengths

  • Runs 14B models: Qwen3 14B at 27.3 tok/s in 11.9 GB

Weaknesses

  • 27–31B models don't fit: Qwen3.8 27B needs 17.9 GB at Q4 vs 12 GB here
  • Little room for context: Qwen3 14B uses 11.9 of 12 GB, 0.1 GB left
  • Slow prompt reading: A 4K-token prompt on Qwen3.5 9B waits 13.5 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 6750 XT has no current price, so it is shown at its MSRP.

RX 6750 XT FAQ

What is the largest model the RX 6750 XT can run?

GPT OSS 20B (20.9B) is the largest at 4-bit or better: at IQ4_XS it uses 11.8 GB of 12 GB, and runs at about 72.6 tok/s.

Can the RX 6750 XT run Qwen3.5 9B?

Yes. Qwen3.5 9B fits at Q4_K_M, using 6.6 GB of 12 GB, and it is the best model that runs well on this card.

Can the RX 6750 XT run 27–31B models?

No. Qwen3.8 27B needs 17.9 GB at Q4, more than the 12 GB on this card.

How many tokens per second does the RX 6750 XT give?

About 40.8 tok/s on Qwen3.5 9B at Q4_K_M, with the first token after 13.5 s on a 4K-token prompt.

What power supply does the RX 6750 XT need?

Plan a 500 W PSU (2× the 250 W TDP).

Is 12 GB enough for coding and agents?

Yes for coding: Llama 3.1 8B Instruct, the only coding-scored model that fits, runs at about 49 tok/s. For agents, not yet: no agent-scored model fits in less than 96 GB.

Is renting cheaper than buying an RX 6750 XT?

An RTX 3090 (24 GB) rents from $0.18/hr. Renting costs as much as buying after ≈3,000 hours (≈2.1 years at 4 h a day).
