USB4 is pretty much Thunderbolt 3, except it's called USB4, okay?!

USB-IF announces USB4 standard, will handle 100W of power over USB-C with up to 40Gbps bandwidth

The USB Implementers Forum (USB-IF) announced today that the final technical specifications for USB4 are here, with the first USB4 products to arrive in late-2020.


USB4 ushers in dual-lane 40Gbps speeds which equal the dizzying heights of Thunderbolt 3, and double what USB 3.2 offered. USB4 will continue making our lives easier taking in the USB Type-C standard, and will be fully backwards compatible with USB 3.2, USB 2.0, and even Thunderbolt 3.

The new USB4 standard will tackle both data and display connectivity, which means we should (hopefully) see a future of more USB4-powered displays. USB3 was alright, but the transfer speeds didn't match Thunderbolt 3 which became important for content creators and enthusiasts who craved, and actually needed, all that speed.
