What we didn't know is that the reduced-price iPad 2 has had a cheeky hardware upgrade. Apple kept that one quiet.
According to AnandTech, the new iPad 2s have dropped the 45nm A5 processor found on the older model and adopted a cheeky wee 32-nanometer variant.
The 32nm iPad 2 is resultantly more power efficient, offering an estimated 16% improvement in terms of battery life while browsing, and a whopping 30% while gaming.
Apple neglected to mention said upgrade during the new iPad launch event, but it’s thought that some iPad 2 units are still kicking around with the 45nm A5 processor.
Unfortunately there’s no way to tell what you’re getting before you get your iPad 2 home, but sites like Geekbench can be used to determine the model number. The newer iPad 2s are iPad2,4, while the older units are iPad2,1, iPad2,2 or iPad2,3.
AnandTech also suggests that the older iPad 2s might ship with iOS 5.0.1 or older, while the newer iPad 2s should rock iOS 5.1 out of the box.
