Verdict
- Radeon AI PRO R9700 is cheaper per GB of VRAM (£48.12 vs £166.87), and cheaper outright by £3,800.01.
- Both have 32 GB, so they fit the same models by our estimate; speed then depends on memory bandwidth and software.
- 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.
