The results should not come as a surprise. Previously we saw this change with the RTX 3070 to 3070 Ti. Even with a mild CUDA core bump, the resulting performance improvement is less than 10% at best, if I am not mistaken. Given that the RTX 3060 Ti is targeted for a max of 1440p, or, low RT performance, the extra bandwidth is not going to make a huge difference. If the upgrade does not result in an increase in price, then its fine. However, I've seen higher prices for the GDDR6X over the GDDR6 version, which makes the upgrade look silly.
