Multiple CPUs, Pipelining, multithreading, onboard graphics, Apple's efficiency and machine learning cores... and multiple CPU cores, as well. The code demonstrated in these examples is essentially executed as a single thread in a single core. Modern CPUs are faster not only because of faster clock speeds, but more CPU cores and peripheral stuff, like cache memory and more, on each chip. Packing the transistors closer together means there's less distance to travel between, for example, the CPU and the arithmetic logic unit, or between the CPU and the on-board cache memory. And I'm sure I've barely scratched the surface.
