USB-IF Association announced that it will launch the USB4 v2.0 specification, which is achieved up to 80 Gbps (10GB/s) of data transmission rates thanks to the new physical layer architecture of the PAM3 signal encoding mechanism. After the update, the maximum bandwidth of USB4 will double, benefiting high-performance displays, storage and various USB hubs/docks. In addition, the USB-C and PD power supply specifications have also been updated and relevant supporting work has been done. The

USB4 v2.0 specification is fully compatible with the latest DisplayPort 2.1, and supports 240Hz refresh rate 4K displays without compression and powering them. USB4 v2.0 can also be configured asynchronous transmission mode, meaning that using the asymmetric mode of 3Tx+1Rx, the host can output 120 Gbps, the slave returns to the host to 40 Gbps, and supports the UHBR20 with the highest specification of DisplayPort 2.0/2.1.

USB-IF Association also released the official name and logo of the USB4 v2.0 specification, called USB 80Gbps. According to the naming and identification of USB previously updated by the USB-IF Association, the original USB4 was changed to USB 40Gbps; USB 3.2 Gen2x2 was changed to USB 20Gbps; USB 3.1 Gen2 and USB 3.2 Gen2 will be unified to USB 10Gbps; USB 3.0, USB 3.1 Gen1, and USB 3.2 Gen1 will be unified to USB 5Gbps. If the cable complies with the USB Power Delivery (USB-PD) 3.1 standard, it can provide 60W or 240W of power, which will indicate the corresponding wattage. USB chargers will also have logos, divided into 100W and 240W.
