LOL !! … Why don’t they just call it USB 4.0 or USB 5.0 (smh)
You would have thought that the USB Implementers Forum (USB-IF) would have learned their lesson the first time around with the rebranding of USB standards; however, that doesn’t seem to be the case. At MWC 2019, they announced that the USB 3.2 standard would include the previous USB 3.0 and 3.1 specifications, but with a twist. USB 3.0, which has a data rate of 5Gbps, had already been rebranded as USB 3.1 Gen 1, will now once again be rebranded as USB 3.2 Gen 1. Meanwhile, USB 3.1 Gen 2 with a data rate of 10Gbps will be renamed USB 3.2 Gen 2. Finally, the new kid on the block which has a data rate of 20Gbps will be officially named USB 3.2 Gen 2×2.
While there is a reason for these names, the fact remains that it doesn’t do consumers any favors. USB 3.2 Gen 2×2 gets its name from the two high-speed 10Gbps channels it uses to achieve the new data rate. Keep in mind that previous USB standards only allowed for one channel, and only USB Type-C connectors allow for dual channels. This, as you may have guessed by now, means USB 3.2 Gen 2×2 is only usable via USB Type-C connectors. To try and reduce confusion, USB-IF has suggested that vendors use marketing terms on top of the current naming scheme to help consumers understand what is what in the world of USB. USB 3.0 USB 3.1 Gen 1 USB 3.2 Gen 1 will be marketed as SuperSpeed USB, and USB 3.2 Gen 2 will be marketed as SuperSpeed USB 10Gbps as per our sources. Finally, the newest standard will use SuperSpeed USB 20Gbps as its marketing term, not that it will do much if implementation of the new standard will take as long as it took for USB 3.2 Gen 2 and the Type-C connector.
