The upcoming iPad Air 2 began to expose parts frequently, which is the most important processor. The exposed part is the motherboard, and there is an obvious A8X display, which means that the iPad Air 2 will use the new A8X processor, and its performance will be more powerful than that of the iPhone 6.
In addition, there is a memory chip from Elpida beside the A8X processor. The letter A in the second line may indicate that 2G memory will be used, which will not be clear until the official announcement.
