Title: Revised iPad 2 with 32-nm A5 Offers 15-30% Greater Battery Life Post by: HCK on May 04, 2012, 03:00:27 pm Revised iPad 2 with 32-nm A5 Offers 15-30% Greater Battery Life
Last month, it was discovered that Apple quietly tweaked the 16 GB Wi-Fi iPad 2, equipping the device with a smaller 32-nm die shrink of the A5 system-on-a-chip previously used in the line. The tweaked iPad 2 carries an internal identifier of "iPad2,4", which was first spotted in an iOS 5.1 beta back in November, but at the time it was unclear what the model represented. A similar die shrink of the A5 was found in the new Apple TV, and it appears that Apple made the move in order to test out production of next-generation chip processes in lower-volume devices. The A5X used in the third-generation iPad continues to be based on a 45-nm process. Anandtech has now |
