Yeah, you just got used to USB 3.0, 3.1 and recently 3.2 right? It has been a confusing mess with the renamed denominators alright. But basically, the USB Promoter Group is finalizing the specifications of the new standard USB 4.0, the first products are expected in 2020.



The USB 4.0 Spec is at revision 0.7 and the USB Promoter Group will finalize it in a month or so with some availability in 2020. Guess what? It is based on Intel's Thunderbolt 3 technology and that achieves per at up to 40Gbit/s.

So that would be doubling up on the current fastest standard at 20 Gbit/s (USB 3.2 2x2). The USB Promoter Group) finds the differences so big that they are considering to create a new USB logo for it. USB 4 would be backward compatible with existing devices with USB 3.2, USB 2.0 as well as Thunderbolt 3. The new standard also adapts support on protocols like display port over Thunderbolt 3.
