From a few searches it seems like in terms of ARM performance it is something like "3x the performance of an RPi4" or, in Geekbench 5, looks like it hits roughly approximate (just a touch lower than) something like an i7-4770S (but again, a bit of apples to oranges comparison, and a single benchmark that might not reflect real-world actual or perceived performance, but might at least give some kind of reference point).
