RTX 3060 12 GB vs RTX 4060 8 GB for local AI
The RTX 3060 12 GB has 4 GB more memory, and that decides it for local AI: it runs a better file (or runs at all) for 39 of 49 models, and 17 run at 8-bit or better against 8. The RTX 4060 8 GB does have hardware FP8, so for models that fit on both it can be faster per step.
