Next generation USB4 spec released, will offer up to 40 Gbps transfer speed

The USB Promoter Group today announced the release of the USB4 specification, the next generation USB architecture. The USB4 architecture is based on the Thunderbolt spec and it will offer double the data transfer speeds along with support for multiple simultaneous data and display protocols. The new two-lane operation using existing USB Type-C cables supports up to 40 Gbps data transfer when certified cables are used. Even though the USB4 spec introduces a new protocol, it will work with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices.

The USB4 specification will be published around the middle of 2019 and you can expect USB4-based devices in the coming months.
