Easy answer is , they don't
Though that's just the one admitting to it.
A lightly more nuanced answer is , it probably depends, there's likely to be some inference made between age ranges but my guess is that it'd be sub-par given that it sometimes struggles with reproducing images it has a tonne of actual data for.
Measures of intelligence are all iffy at best, but I’m pretty sure "being better at raw math" isn't a good one in isolation, especially seeing as that has been the case for a very long time.
CPU's and GPU's are basically just doing really fast math repeatedly.
That aside i'd, challenge you to find a universally accepted definition of "human intelligence" that works as a benchmark we can also use to measure machine intelligence.
afaik, we're still murky on whether or not we are just really efficient specialised computers working with electric meat instead of electric stone.
The term normally used when talking about MI that is similar enough to human intelligence is AGI and even then, there's not consensus on what that actually means.
