We've reached a point where you really can't get that much more frequency out of chips, and there's only so much you can do to attempt to get more done per clock cycle. Especially now that its made clear that much of these attempts lead to the various speculative execution bugs like spectre that have been discovered over the past few years. The days where clock speeds on processors was doubling every year or two are long gone, and its not because chip makers have gotten lazy.
