this apu could end up in the new nintendo console

Minor typo at the end of the second sentence, 'scars' instead of scarce. I can't believe there are rumors for the 400 series when the 300 series doesn't even have confirmed specs XD.

Supposedly both Xbox and PS4 are looking at a faster release cycle for their consoles. Basically, they realise that any new 'generation' of console simply can't last as long as the Xbox 360/PS4 did, especially with the increasing processing capabilities of phones, and even TV's now (with some upcoming 2015 models having significantly greater gaming capability). The current consoles are supposedly going to be replaced around 2017, perfect timing for AMD's next generation APU's. I believe that is planned for at least those 200-300W APU's rumoured. Not sure how much they are talking about, it's most probably a supersized L3 or L4 cache versus RAM in the traditional sense. It's possible that it will be featured across all the upcoming AMD processors, just in varying amounts. The real question is, how long will DDR4 be around considering the advances with HBM? Even basic HBM is a far more attractive proposition than DDR4, and the costs could actually be kept down. The costs could be kept down simply because HBM on graphics cards (and on the APU's) have a different focus point in the cost/performance balance. The focus for graphics cards is performance, so it comes at a cost. For normal RAM, although performance is an important aspect, they will keep the costs down by having a lower performance versus cost. This move is inevitable, it's just the timing of when such move takes place. It would definitely be a better proposition than DDR4, considering its performance increase and better efficiency, in say, 2018, but the cost of implementation may sway that until a later date.
