It's a term that was relevant in... the 1990s and last generation, but this generation they're using x86, something that every developer in the universe knows how to code for. What we're seeing now on the PS4 and Xbox One is about as good as it's gonna get.
Well, given the fact these are pretty much single thingy-oriented systems, the optimalization is probably pretty high, since I imagine they are doin' lotsa stuff on HW...
