Intel competes first and foremost against itself. If they don't evolve, people won't upgrade. A competitor just adds to that pressure, but it is not, and should not be the main force pushing Intel to evolve.
What we are seeing is performance stagnation in desktops, but that's to be expected, the money is to be made elsewhere, so all companies will put their energy there, not in desktops.
Would you mind showing this plethora of AMD chromebooks? Because I can't find a single one.
Most people don't need 4770K speeds, but they certainly need more than the 7850K CPU, and even more people need more than 7850k CPU but don't want to go all the way up to 100W to get that performance.
But if you care enough about graphics, you still have other ways to deal with it? You have a plethora of discrete GPU that can offset the weakness of Intel GPU,
Unfortunately for AMD you cannot buy a discrete CPU card to offset the weakness of the CPU part of their APU.
