But Snapdragon 820 is still faster than A9 overall

Earlier this week, a hands-on performance comparison between Apple’s crown jewel of 2015, the iPhone 6S Plus, and Samsung’s crown jewel of 2016, the Galaxy S7 Edge, was uploaded to YouTube where real-world performance was tested side-by-side to see how fast each phone runs a sequence of various apps.

 China's regulatory agency says so, so it must be true

Last year's iPhone was shipping with 20nm Apple A8 processor clocked at two times 1.4GHz and now it seems that the A9 works at two times 1.8 GHz. 

16nm process might be a better choice than Samsung’s 14nm

TSMC is reportedly getting the majority of Apple A9 orders, which would be a big coup for the company.
