USB 4 Version 2.0 promises 80 Gbps, new active cables will also come

The USB Promoter Group announces that a new standard is coming USB4 Version 2.0, which should push up to 80 Gbps (10 GB/s) via the USB-C connector. That’s double today’s 40 Gbps. The specifications for both USB-C and USB Power Delivery will be updated and their publication is expected this November. Protocol updates will also concern the USB 3.2 interface (they are now supposed to handle over 20 Gbps), DisplayPort and PCI Express.

There will be a new physical layer architecture, but existing passive 40Gbps USB-C cables as well as newly defined active USB-C cables for 80Gbps connections will be available. Backwards compatibility is to be ensured with USB4 Version 1.0, USB 3.2, USB 2.0 and Thunderbolt 3. The announcement now concerns developers, the final decision on how to mark the new standard on final products (both on cables and devices with these ports) will be decided later.
