USB 4 V2 specs look interesting
 

Up to 80 Gbps

The new version 2 of USB 4 will use the USB-C connector and manage up to 80 Gbps operation.

According to a small amount of information which is about as official as a Donald Trump clearance on top security documents, the new cables are based on a new physical layer architecture, using existing 40 Gbps USB Type-C passive cables and newly-defined 80 Gbps USB Type-C active cables”.

Joe Balich, a spokesperson for the USB-IF, confirmed that if I were to go out and buy a USB 4 cable right now that was rated for 40 Gbps, it would be able to do twice those speeds in the future. The fact that you can use your old cable on the new standard is pretty cool.
