I think NVidia is going to have to cut prices on the 4060 Ti because even if AMD gets no performance gains over the 6800 XT, this is still going to stomp both variants of the 4060 Ti.
I don't think so.
16 GB 4060 Ti doesn't enter the picture. NVidia and partners don't care at all about 16 GB, 4060 Ti. Only a few models seem to exist and those are barely in stock. It's an irrelevant card for the most part. NVidia seems happy to have it fail, so they can say "we tried high VRAM and no one bought it". No one, not buyers, not AIBs, and not NVidia seem interested in this card, so competition isn't going to drive them to do anything.
So it's really about the $400 8GB 4060 Ti vs $450 7700 XT. But the NVidia cards is already $50 less, so I don't see NVidia moved to do anything at all. Remember when the slower
and more expensive RTX 3050 was outselling the faster and cheaper RX 6600? What possible pressure do you think the more expensive 7700 XT is going to put on NVidia to lower the already cheaper 4060 Ti, pricing? If the 7700XT was the same price there
might be a case, but not at these prices.
So no I don't see that NVidia will feel any pressure to cut 4060 Ti prices at all.
OTOH 7800XT is better position offering more performance for $100 less, so if there is a cut needed, $50 off the 4070 could really protect a card they seem to care about, but they probably won't.
Of course if they really wanted to stab AMD in the heart, they would release a just slightly improved 4070 Super, for $550... being close in price and slight above 7800 XT performance right after. That would cut off the oxygen supply, but again, they won't.
