The interesting thing is about moving to a smaller node process is you can effectively get 2 options out of it. Either lower power consumotion or more performance. I can't find the article but i read that in the case of the Xbone and PS4 they would both get roughly a 20% reduction in power or they could get 20% more performance at the same power efficiency they currently have. Now obviously they won't get more power out of it(counter productive but for a reason) because that would anger fans around the world. They bought the console and a year later they came out with a smaller but faster version? It would be cool but its really only for dreamers..
Just thought i would share that with y'all
