We were talking about emulation and how the underlying design of systems, which chips are used, makes that emulation difficult. It seems consoles at first had off-the-shelf chips that were put to a new and interesting use (NES/Master System era). As the generations went on, the chips got more specialized (XB360/PS3 era), but did not veer too far from the established general-purpose PC architectures. After all, the xbox series used custom x86 chips with a special instruction set and odd behaviors, and the PS3 used a powerPC derived chip. Now both the PS4 and XB1 are using x86, a more general-purpose chip.
Which direction are the going to go next? Are we going to see a media/gaming optimized x86 series of chips? Or are we going the way of Sony/MS branded Steam machines with custom OS's?
I think the former would be a more fun experiment. X86 has that whole backwards compatibility and bolted-on instructions baggage it's been carrying around for years. Maybe between Sony, MS and (maybe) Nintendo, they can prune out some of the unnecessary crap and make the chips feel faster.
