Back of the hand math, and some benchmarking, suggests that a consumer laptop GPU from about 2015 could bang it out in a month. And, that's being (extremely) pessimistic. (Assuming a GPU takes .001s to do a sha3 hash, which is more than double the actual benchmarks). I would estimate that a single, high end GPU from the last or current generation could probably chew through it in under a week.
