The USB Promoter Group just announced the new USB4 Version 2.0 standard enabling transfer speeds of up to 80 Gbps, which is twice as fast as the previous version of the same protocol.
The new active 80 Gbps Type-C cables are backwards compatible so you can use them with connectors supporting USB4 1.0, USB 3.2, USB 2.0 and Thunderbolt 3 and vice versa – older USB-C cables will work on USB4 Version 2.0 ports even if they won’t deliver the high speeds.
The biggest advantage of the new protocol can be utilized by high-performance displays, storage and hubs and docks.With 80 Gbps of bandwidth, you may be able to connect an external GPU to a laptop and get a desktop-like gaming experience with little to no compromise in performance. Moreover, the new standard plays well with the latest versions of DisplayPort and PCIe.
More details about the new protocol will be shared during the USB Developer Days 2022 conference on November 1.
