USB4 20 Gbps: Also known as USB4 Gen 2x2

USB4 40 Gbps: Referred to as USB4 Gen 3x2

USB4 80 Gbps: Known as USB4 Gen 4

USB4 Version 2.0 120Gbps

I guess if you're required to support 120Gbps on even cheap small electronics then USB 4 support doesn't make sense



Is this confusing naming scheme intentional?


I think so. They're been going at it since usb 1.1 super speed or not super speed.

And btw the list above includes only the data speed, not the charging capacity.


It's still better than deliberately incompatible schemes, meaning you can't charge your small device from laptop charger.


I think they mean "USB4 Version2" when it clearly isn't "version 2" but "version 5" or whatever.


Yes.
