Intel recently announced its 2018/2019 CPU, called Icy Lake. AnandTech explains the new chip in detail. To summarize, Intel is putting the hammer down on making their chips smaller and faster. I'm sure Apple and other competing chip designers/manufacturers are taking note.

As I was growing up with computers, CPU improvements were all about speed. Computers didn't change the way they looked so much as they got a lot faster … often. I can't help but feel that as 10nm chips become "the thing", the speed improvements will end up taking a back seat to the ways these new chips liberate hardware manufacturers to rethink the kinds of hardware we can put these small, fast chips in. Future chips are not about getting faster (although they will get faster) so much as they are about further evolving the idea of what a computer is. I can hardly wait.
