    Been seeing a lot about the specs of the playstation 4 and the xbox 1 (80) and it seems im missing something here. See both consoles are on the 32 bit (x86) architecture, which i was always sure the limitation for useable ram was 4 gig max, so what has changed, if anything to now have the original goalposts moved.

    I think you maybe confusing x86 (which is an INSTRUCTION set) with the fact that it is a 64-bit processor (which has nothing to do with the instruction set).

    The processor is 64-bit compliant.

    Ok, so these instructions are in 32 bit, but run on a 64 bit processor ???

    Yep, that's right.

    Remember that "x86" started off as a 16-bit instruction set!

    I have quoting wiki, as it's so full of errors but this about covers my understanding of its history...
