Our A700 is a quad core, right? Well no, it is a PentaCore. 5 Countem, Five. I was supprised to learn it spends most of its time running in the 5th core, which is a low powered 500mhz core. Any time you tap anything, it wakes up the 1.3Ghz quad cores, as many as it needs and gets them all turning and burning. I was under the impression it only used the 5th core in sleep mode, but that appears not to be the case.
