Well ... Moore's Law is not about speed, but the number of low cost transistors you can economically put on a single die. How that translates into "speed" is complicated, e.g. when you're first able to put all of a CPU on a single die you get a big speedup. After this was written raw clock speeds hit a wall, all that's left is microarchitecture improvements, including making things wider, making dies wider by putting more cores on them, and adding lots of cache. Hmmm, and a whole lot of architecture work has by and large ended up on the garbage heap of history, or is no longer trying to compete in speed. Plus ARM has always prioritized power over speed.
