Since the launch of the iPad Air 2, everyone has been interested in the A8X on it. Apple claims that the CPU is 40% higher than that of the previous generation, and the GPU is 2.5 times higher than that of the previous generation. From the data of the scoring software PassMark, it seems that the structure of A8X is very special.

From the CPU performance test, the running score of the iPad Air 2 (as the model is not recognized, the code names iPad5,4 are used in the figure) is almost 1.6 times that of the iPhone 6 and iPhone 6 Plus using A8. And there are three CPU cores identified, so we think the A8X is most likely a three core or even four core SoC (if the dual core is still maintained, the performance of the A8X should be 1.6 times that of the A8, and the frequency of the A8X should be 2.3 GHz, which is not Apple's style).

In memory test, although the performance of the iPad Air 2 is not good, we noticed that the RAM capacity identified by the application reached 1987MB, that is, 2G memory was used. This is also the first iOS device to use 2G Ram. I believe many users have been looking forward to this moment for a long time.
