Chess AI used to dominate by computational power but to my knowledge that is no longer true and the engines beat all but the very strongest players even when run on phone CPUs.

Phone cpus have gotten quite fast in the past decade, too.
Deep Blue analyzed some 200 million positions per second. Modern engines analyze a three to four orders of magnitude fewer nodes per second, but have much more refined pruning of the search space.
Point taken.
Positions analyzed per $, per W and per watt-dollar are surely much, much higher, though ;)
20 thousand positions per second is still a lot compared to a human though.
