According to Boy Genius Report, the next iPhone will run on the same A5 chip that powers the latest iPad. The rumor is based on code spotted in iOS 4.3 that uses the same processor codename when referring to both the iPad 2 and an unidentified future device.
Apple’s A5 chip has a 1 GHz dual-core processor, which in terms of tech specs is on par with cutting-edge Android smartphones such as Motorola’s Atrix 4G. The extra processing core is like a second brain, allowing the phone or tablet to handle more tasks at once. Apple’s website claims that the A5 is noticeably faster than single-core processors when moving between apps, multitasking, making video calls, surfing the web and playing games.
The processor alone doesn’t paint a very clear picture of the iPhone 5 though, other rumors have suggested that the phone will have a 4-inch display — up from the iPhone 4′s 3.5-inch screen — and an aluminum backing instead of the existing model’s glass pane.
It’s a little too early to put much stock in any of those rumors, but the A5 seems like a safe bet.
