Verdict
- RX 9070 is cheaper per GB of VRAM (£38.55 vs £60.00), and cheaper outright by £103.16.
- RX 9070 has more VRAM (16 GB vs 12 GB). The biggest Q4 model we track is the same (Phi-4 14B), but the extra memory gives more context headroom and fits up to Gemma 3 12B at Q8 vs Qwen3 8B.
- If you want the easiest setup and the widest tool support, NVIDIA's CUDA is still the safer pick; AMD works well in llama.cpp-based apps.
This is a value-for-memory verdict for local AI, not a gaming benchmark. We haven't measured tokens/sec.
