USB-C naming gets complicated with USB4 2.0

The USB Promoter Group recently announced its new USB4 2.0 standard that has made the USB naming criteria even more difficult. The official press release stated that the new USB4 2.0 standard will bring faster speeds for USB cables.

It offers transfer rates of up to 80 Gbps, almost twice the transfer rates on USB Type-c Thunderbolt 4. In addition, it provides increased compatibility with USb4-compatible and also supports active Type-C cables at speeds of up to 80 Gbps.

“Yet again following the USB tradition, this updated USB4 specification doubles data performance to deliver higher levels of functionality to the USB Type-C ecosystem,” said Brad Saunders, president of the USB Promoter Group. “Solutions that take the most advantage of this speed improvement include higher performance displays, storage, and USB-based hubs and docks.”

When it comes to naming, the USB criteria have always been a source of headache. There are categories with subcategories and even further iterations and now the same will be true for USB4 which already has a second variant.
