Re: Xbox 720 specs rumour suggests a giant 16-core CPU
It could have the grunt needed if it were maybe a 16-core A15 CPU maybe. Could be custom built. Though I doubt they will be going ARM. A true 16-core processor, here ARM, just sounds stupid imo if that does end up happening.
It being a PowerPC by IBM chip is most likely imo. All 3 current systems are PowerPC based with IBM involvement and the Wii U is PowerPC based.
