This PR claim is nothing but hogwash and lies. Mobile will not be more powerful than PS4 in 2017. Here is why:
Moore's Law
Many of you may have heard of this and seen it used in tech writings but don't fully understand what it means.
Moore's law is a mathimatical proof about the density of transistors doubles every 2 years. With that the potential max power of a given chip with a given surface area will double every 2 years also. Keep in mind that this is just the upper bound meaning that at most the performance doubles every 2 years. There have been many points in history where industry has failed to keep up with moore's law and has fallen behind.
Lets say that even today that smartphones are somehow more powerful than the PS3/Xbox 360 (They are not and not even close). In order to beat the PS4 arm chips would have to increase in power more than 804% by the end of 2017. Using moore's law that would be physically impossible, It would take the better part of 8 years even if they somehow managed to keep up with moore's law. That would be 2024 not 2017. Very much a lie not even clever PR talk but a boldfaced lie.
