the 9070xt is the 7800xt replacement though, not the 7900xt or 7900xtx..hense why it's a 16gb card...renaming their cards to 'be in line' with nvida..urgghhh why. Just make a good card and do your own thing..gamers can work it outLess VRAM than the 7900XT though.
How important that will be though we'll have to see.
I know last gen when AMD had 20/24GB and Nvidia had 16GB it was quite a big deal, now that AMD have 16GB I'm guessing it won't be such an issue.
