That is the biggest out and out lie I have ever read from an executive, and that is saying something. We KNOW what is in the PS4 and xbone, with the PS4 having the more powerful hardware.
What is in there is an AMD APU, a low power, multicore CPU with a GPU on the same die. They are equivalent, in raw power, to a midrange current gen system. Compared to even a stock clock i7 and 7970/Titan/GTX680, they are slower.
Sure, developers will squeeze more out of that on the consoles than they would on a PC b/c they don't have to deal with the overhead of Windows and APIs like DirectX but at best that means that practically they are six months ahead of PC, as substantially more powerful 20nm graphics cards will be out either end of the year or early next year.
But what did anyone expect from Xbone marketing speak? The god's honest truth? Or self promoting lies?
