The USB4 2.0 specification is coming: Double the speed to 80Gbps
The USB Promoter Group has announced the upcoming release of the USB4 2.0 specification. This is a major upgrade from USB, enabling future data transfer rates of up to 80 Gbps via a USB Type-C cable. The USB Type-C and USB Power Delivery (USB PD) specifications will also be updated to enable higher levels of data performance. The USB DevDays series of developer events will be held in November this year, and it is expected that the relevant specifications will be updated before that.
