Well, I looked at the link you posted, but before I do, could you please look over the link I posted once.
There is a process node guess from 85 on the left and it says why tsmc 7nm and Samsung 8nm are not reasonable choices.
Then about the Xbox refresh.
What I am hearing is that the transition from 7nm to 6nm is officially recommended by tsmc and requires no redesign, so there is little cost to the transition.
Production costs will also be lower.
The Xbox refresh is about lowering costs and improving production capacity, not increasing performance.
That is probably why we chose 6nm.
