Apple's A11 processor is still way ahead of Qualcomm's latest 10 nm processors. The Galaxy S9/S9+ will have the Snapdragon 845 in its next device release. Apple controlling the entire process allows it to optimize its processors to perform very well, albeit iOS 11's buggy release. In addition, there isn't a need for 6gb RAM or something like that to get strong benchmark results on the iPhone 8/8+/X.
I am curious to see how great a possible A11 X will be in the next gen iPad Pro and how the A12 processors do in the 2018 iPhones. We could even see smaller sizes than 10nm processors.
