The USB Promoter Group has just announced the new USB4 version 2.0 standard which enables transfer speeds of up to 80 Gbps, twice as fast as the previous version of the same protocol.
The new 80Gbps active Type-C cables are backward compatible, so you can use them with connectors that support USB4 1.0, USB 3.2, USB 2.0, and Thunderbolt 3 and vice versa – older USB-C cables will work on USB4 version ports 2.0 although it will not provide high speeds.
The biggest advantage of the new protocol can be used by high-performance displays, storage, hubs and docks. With 80 Gbps of bandwidth, you might be able to connect an external GPU to a laptop and get a desktop-like gaming experience with little without any compromise in performance. Furthermore, the new standard works well with the latest versions of DisplayPort and PCIe.
More details on the new protocol will be shared during the USB Developer Days 2022 conference on November 1st.
