We have heard a lot about the A6 chip. Since the iPhone 4/iPod touch 4/iPad with A4 chip to the iPad 2/iPhone 4S with A5, regardless Apple’s next-generation mobile phone called the iPhone 5 or other names, as well as next-generation tablet PC called the iPad 3, we all think both products internally equipped with A6 chip.

But not long ago, the media leaked the so-called “iPad 3 motherboard (below), which clearly shows the words of A5X. In other words, the iPad 3 is not equipped with the A6 chip, but the enhanced A5 chip, and it is still dual-core instead of quad-core. The media also this lists the relevant evidence: A4 chip – S5L8930X, A5 – S5L8940X, A5X – S5L8945X, there is no directly plus “10″ in the number mantissa, but “5″.

In people is still discussing the iPad 3 may with A5X or A6, media dug out a iOS 5.1 Beta internal code Screenshot: Which shows Apple is testing A5X and A6 chip. We can see, S5L8945X and S5L8950X simultaneously exist, these two chips will born at the same time?

Who does not know how Apple will plan to use A5X and A6, that may represent a Plan A and Plan B, also may refer to two different devices, such as the A6 = the iPad 3, A5X = iPhone 5. Such information found in the iOS 5.1 beta might means iOS 5.1 official version will be released along with the iPad 3 (Two models) at the same time.

Anyway, we all hope that Apple will bring “very stunned” products this year.
