Last time I checked, all the computers were growing powerful and crypto was relevant neither for latency nor for power consumption on any device capable of joining a network.
It helps that one of the largest factors on choosing crypto algorithms is speed on both general purpose and specialized hardware.
So, count me in the group of people that don't understand why the NIST is doing this. Will they trade any security guarantee for speed? If so, nobody should ever use one of those algorithms. If not, whatever algorithm wins here would also win a new round of general purpose crypto contest.
