More important is “size of a team of humans” vs “peak capabilities of a team of humans” (or maybe sum of the cubes of their IQs?)
A given person thinking faster than average is more equivalent to a multiplier on the number of people of exactly that intelligence you have.
(Of course, if you could radically increase brain speed, I would expect IQ to increase rather than remain constant, but that isn’t yet an option for humans).
