For example Ubiquiti lists their Unifi U6+ at 1.2gbit and the U6 Pro at 4.8gbit. But the speed these two products will achieve in a home or small office is exactly the same. The Pro has some more range (bigger antennas), but both will get you about 700mbit in ideal reception no interference conditions because they're based on the same WiFi 6 standard.
Edit: And they know it, both products have a 1gbit physical port that is enough to serve "4.8 gbit wifi"
