Early last week, USB Promoter Group announced USB 4 Version 2.0, a significant update to the USB standard. The first gen was introduced in 2019 as a bit of an overhaul to the USB 3.2 and USB 2.0 architectures by doubling the speed and further incorporating Thunderbolt. Now, USB 4 Version 2.0 aims to double the speed again, with performance improvements coming to USB 3.2 as well.

The announcement of USB 4 Version 2.0 is an important update as it enables higher available bandwidths and up to 80Gbps of data performance through USB Type-C cables and ports, USB Promoter Group says in a press release. That’s double the current top speed, which is 40Gbps. Alongside the USB Type-C, the USB Power Delivery (PD) specifications are being updated for “higher levels of data performance.” However, further details on the specifications won’t be published until November.
