Exactly you always here about xbox fans saying they haven't utilized this and that, but remember that both machines are made by amd so do people think that xbox is going to get performance gains over the playstation4.Whatever gains are made by devs on xbox can easily be applied to ps4 because of the similar architecture's.
you're just repeating what we've known for months already ! the apu's are totally different even though they're made by AMD

no they're not ! the only common part of the apu's are the jaquar core's and thats not even running the same speed on both systems

The CPU and GPU's are both AMD (combined APU) and they are indeed built on exactly the same architecture, so just like a Radeon 7750 is the same architecture and the 7850, the one just has a higher count of the same "stuff" so it's inherently faster.
PC enthusiasts would understand exactly the kind of technical lead the PS4 has over the Xbox One and no amount of software optimisation is going to close that gap.
