Editor's note: Most of these improvements can be gained by simply shifting to the new 10nm process.

One of the most significant announcements of the September 12 Apple event was the company’s self-designed GPU – yet it was the announcement that got the least amount of applause. It is clear that the audience did not immediately get the ramifications associated with Apple designing its own GPU featured on the A11 chip. Without any sort of exaggeration, I can say that it was probably one of the most important unveils of the event (yes even more important than the iPhone X) if not the most important.
