If something is roughly as intelligent as a normal human expert in a given area, but 100 times faster, that would be a valid example of super intelligence.
I'm sure that by some definitions like this we've already discovered narrow super intelligence.
For example - breadth of knowledge. Is knowledge a kind of intelligence? If so then current agents absolutely have a breadth of knowledge which is superhuman.
Tortious really does win the race, and there is no such thing as a free lunch.
