Version 2.0 of USB4 should soon see the light of day. It promises a transfer speed of up to 80 Gbps.
The new USB 4 standard – version 2 will be able to reach speeds of up to 80 Gbps thanks to new active Type-C cables. For comparison, the first version of USB 4 is limited to 40 Gbps. This speed increase is possible thanks to a new physical layer architecture. The latter uses “the existing USB Type-C 40 Gbps passive cables and the newly defined USB Type-C 80 Gbps active cables”. The technology will of course be backwards compatible with the old USB connectors.
Please note that this new version is called “USB 4 Version 2.0” and not “USB 4 Gen 2” as is the case with the different versions of USB 3. Here is a brief summary of the nominations:
At this time, it is unknown when this new standard will be available to users. According to the USB Promoter Group, “this update is specifically for developers at this time”.
