As if it's possible to put a simple percentage on that.
Surely with customised parts and such each console will have strengths and weaknesses in different areas of computing and graphical performance... Sure maybe overall the PS4 is slightly more powereful but why do people have to give this amount of fuck.
btw I don't have a source or anything, but around the PS3 launch I remember it was supposedly capable of 2 Teraflops, wheras the PS4 is supposedly only 1.8... perhaps I am getting wires crossed between theoretical and real performance here (though I thought floating point performance was only theoretical)
