Back in March 2019, the USB Implementers Forum (USB-IF) announced the existence of USB 4. Its announcement was a bit of a surprise, primarily because the USB 3.2 standard was still being rolled out. Compared to USB 3.2, USB 4 will feature dual-channel connectivity, which will enable transfer speeds as fast as 40Gbps. The standard will still be based on Intel’s Thunderbolt 3 interface and will still be built using the existing USB-C design. Of course, it will also be backwards compatible with USB 2.0 and USB 3.2.
As mentioned in our earlier report, the applications of Thunderbolt 3 are near endless. It can be used as a connection to an external hub; expand the number of ports through a third-party docking station; run multiple 4K displays, and even support super-fast charging speeds at wattages as high as 100W.
