Apple has confirmed that the SoC powering the super-thin iPad Air 2 is going to be the rumored A8X chip. It's still a 64-bit architecture and it is the home of 3 billion transistors that do the calculations under the hood. Apple claims that the graphic performance of the new iPad Air 2 will be 2 and 1/2 times faster than last year's iPad Air. And, of course, it supports Apple's Metal API that was first talked about at the iPhone 6 event and is said to enable "console-level graphics" on Cupertino's latest mobile devices.
The A8X also handles an Apple-designed image signal processor, which enhances the capabilities and fluidity of editing pictures. The main processor also got an updated buddy - the M8 co-processor. Much like last year's M7, the M8 is there to track motion, location, and elevation, leaving the A8X free to work on the more serious stuff.
Even with the super-thin profile and performance boost, Apple claims that the iPad Air 2 will still allow up to 10 hours of on time.
