Verdict
- RTX 5070 Ti is cheaper per GB of VRAM (£67.50 vs £85.00), and cheaper outright by £279.99.
- Both have 16 GB, so they fit the same models by our estimate; speed then depends on memory bandwidth and software.
This is a value-for-memory verdict for local AI, not a gaming benchmark. We haven't measured tokens/sec.
