What I read at neogaf that PS3's CPU is really powerful. So much so that its difficult for PS4 to emulate it; since a generation gap in power is needed. But if they manage it then it will be awesome.

However, emulation is not the only way for backwards compatibility, XB1's backwards compatibility for instance, is not emulation.

But what is it then?
