The confirmed specifications of USB version 3.2 announce a doubling of speed

The group working on the development of the USB port confirmed the specification of USB version 3.2 yesterday. The main difference between this version and the previous version (3.1) is the addition of the simultaneous and separate functionality of the host and the device. This function means doubling the bandwidth on existing SuperSpeed ​​Type-C cables. In simpler words, the speed of this communication port will increase up to two times on SuperSpeed ​​Type-C cables available in the market.

USB 3.1 ports are designed for single-channel use between the host and other devices. On the other hand, SuperSpeed ​​cables are designed for two-channel communication. Of course, so far, this feature has not been used much; Because the hardware specifications of common devices do not allow them to support dual-channel operation.

The aforementioned problem will soon be solved thanks to the new capabilities of the USB 3.2 port. All new devices using the USB 3.2 port are supposed to support dual-channel communication, which enables twice the speed of existing cables.

Current USB cables that The first generation of SuperSpeed ​​cables are supposed to support data exchange rates up to 10 Gbps, which is a significant improvement over the current 5 Gbps rate, and in generation 2 cables, data exchange rates up to 20 Gbps. It will arrive.

The USB development group is finalizing the USB 3.2 specification and plans to release it in early September so that developers can follow these guidelines when building their products.
