USB4 Version 2.0 is a significant update to the USB4 standard announced by the USB Promoter Group. This version aims to double the data transfer speeds from the previous USB4's 40 Gbps to an impressive 80 Gbps. This increase in speed can be achieved using existing 40 Gbps USB Type-C passive cables and new cables designed for the updated standard.

USB4 Version 2.0 was officially released on October 18, 2022.

The specification introduces a new physical layer architecture enabling higher transfer rates. The USB4 Version 2.0 supports dual-lane operation, allowing 40 Gbps per lane in each direction, effectively achieving 80 Gbps.

This update is expected to enhance devices' performance capabilities, providing faster data transfer, improved power delivery, and better support for high-resolution displays and other demanding applications.
