Not quite the same but I was looking at PowerBook G4 specs last night. Apple was doing gigabit ethernet in a mid-priced laptop ($2200 in 2001 dollars) 25 years ago. Meanwhile I'm pretty sure I have some 10baseT gear kicking around.

It’s not the same thing! Pico is a microcontroller, it’s also not a native ethernet implementation.

That would have had a dedicated chip doing the work.
