Ofcourse low powered Chips for Phones in 20nm is no problem. But the APU in Xbox/PS4 is not low powered it needs like 20 times more Power then a Phone. Nvidia is precisely not satsified with 20nm because it does not offer a cost advantage. Why would Sony do it if they dont see a cost advantage or MS for that matter. They are accesible theoretically but I doubt its a very efficent and cost effective solution atm.  And I dont see a Slim coming before the 20nm node produced some high end gpus atleast.

i don't think you know how chip manufacturing works. And that would mean that it will take too much work to explain all this to you. 

And Nvidia is dissatisfied for a lot of different reasons. Again its best to read up on that, they had a whole presentation calling out their chip manufacturer.  



I read that ages ago and I think you are accusing me of not knowing but you have no clue yourself.

The problem with high powered GPUs is that the electron leakage is a bigger problem because more electrons have to go through the thin circuitry, and they are bigger meaning a bigger piece of the waver has to be perfect. With lower performing smaller chips its more forgiving. The yields for 20nm high performance chips were abysmal and offered no costadvantage. Which is why Nvidia was disatsified with the Node. TSMC was incapable of delievering enough perfect big chips. making it too costly for Nvida and AMD to jump to 20nm. The phone industry doesnt need big chips so they could live with the process quality. before we dont see AMD and NVIDIA with 20nm gpus there is no way we see a shrink for PS4/Xbox one they have even less room to unload the additional costs to their  customers (exactly zero room) so they will be last on the 20nm Node. Its logical. Before there is no GTX 1080 we wont get a Slim PS4/Xbox one (atleast none with a 20nm APU).

 

You can read up about it on the known forums let someone that knows more then me explain you the difference between high and low performance chips and the consequences. I have googled for you http://techsoda.com/no-20nm-graphics-amd-nvidia/ you can read this first if you want. You are welcome.
