The claim that an A12(x,z) is equivalent to a XBox S gpu is based on the same kind of games.
What games? Are you sure you quoted the right post? I was talking to the only published marketing material on Nvidia Ampere, which does not mention games at all. There are some gaming benchmark leaks that suggest an improvement of ~ 25-30%, which is normal for a gen-to-gen increase. Certainly nothing like "3060 beating a 2080 by 2 times" like what you claim.
