Are you suggesting that lessons learned by AMD and Global Froundries with getting better power characteristics and yields at the Fab level will not benefit everyone?
Because that would be false. And I assume that is what you are arguing against.

And I get we are talking about chips using the same architecture on the same process. I have explained how it would be possible for one to be smaller, cheaper and more powerful.

I'm suggesting that not ALL leasons learned will carry from one to the other because of the specific process... PS4 and X1 use the same architeture and still PS4 is cheaper to produce because it have a bigger bulk and got more cost cut due to it and leasons learned because of it, while X1 got some of the leasons learned from PS4 it didn't get all because both chips have differences.

How are you saying about the same process and architeture while assuming PS4Neo gets the bigger node and Scorpio get the smaller node, because of reasons?

I never said that Scorpio get's a smaller node than Neo. - Perhaps you are getting the terminology confused?

And you are right. Most non-fab related lessons/improvements will not carry over between the two, but that's also not the argument we are having.

Also the Xbox One chip as far as I know is larger than the PS4's, so it's more expensive to manufacture on size alone.
However... Not sure if the eSRAM can get away with cheaper patterning though as it's an inherintely simpler and predictable structure just like NAND.
