The scoring is fully transparent: see our methodology for details on VRAM/tokens/sec calculations.

Frequently asked questions

RX 7800 XT vs RX 9070?

9070 = RDNA 4 (2025), 7800 XT = RDNA 3 (2023). Same 16 GB + similar bandwidth. 9070 is slightly more efficient + ML accelerators. See RX 9070.

7800 XT LLM sweet spot?

Mistral Small 24B Q4 (~13 GB) at 22 tok/s, Qwen 3 14B Q5 (~10 GB) at 32 tok/s.

Easy ROCm 6 + 7800 XT?

Yes: Ollama install + flag -gpu rocm = it works. Same with llama.cpp. vLLM AMD is improving but less stable. See guide.

7800 XT or RTX 4070 Super?

7800 XT = 16 GB + ROCm, 4070 Super = 12 GB + mature CUDA. For accessible 24B models, AMD. For pure speed on 7-14B, NVIDIA. See RTX 4070 Super.
