That’s double the transfer speeds of USB 3.1 Gen 2. USB 3.2 will be capable of 20 Gbps speeds. Last September, the USB-IF detailed out new possible speeds for USB-C, and the beginnings of the USB 3.2 specification. USB 3.2 is Even Faster and More Confusing USB-IF To help differentiate the speeds, USB-IF also implemented logos, which manufacturer can only use by passing a certification to prove a cable matches the promised specs. But, as long as you remembered Gen 2 was better than Gen 1, you were good to go. The difference between the two was slightly confusing. Full-duplex communication is exciting because that means information can be transferred and received at the same time. Technically, it accomplishes this by using 128b/132b encoding in a full-duplex communications mode.

USB 3.1 Gen 2 is capable of 10 Gbps transfer speeds-that’s called SuperSpeed+. USB 3.1 Gen 1, originally known as USB 3.0, is capable of 5 Gbps transfer speeds-that’s called SuperSpeed. To further complicate things, the transfer speeds themselves received names.
