The speed of an encoder really comes down to how many optimizations it's searching through. The AV1 format allows a lot more options when encoding, so encoder writers kinda feel obligated to try a bunch of them out to see if they save bandwidth. But if instead a codec just picked a few optimizations and ignored the rest, it could be pretty fast. Maybe Google just found a set that worked well for an average video chat.
