It was almost two years away from announcing the USB 3.2 specification, which ended up delaying its movement due to the launch of USB-C. Today, at MWC 2019, the USB Implementers Forum (USB-IF) finally confirmed the arrival of a new USB 3.2 standard in 2019.
USB-IF mentioned that the drivers that support USB 3.2 will be published in the coming days. Indeed, the first PCs with USB 3.2 support should arrive at the end of this year. Although USB 3.2 is a punctual update, the reality is that is close to Thunderbolt 3 and its 40Gbps, and that USB 3.2 will be able to offer speeds of up to 20Gbps over USB-C.
First Compatible Devices Will Arrive In 2020
Here it is necessary to emphasize that although the first basic plates arrive during the second half of 2019, it will not be until 2020 when we begin to see the first peripherals and compatible components with this new standard. In addition, not all will be compatible with the maximum speed, since this will depend on the manufacturer and what they seek to offer in their devices.
Regarding the technical details, this new USB 3.2 standard will allow to use two Tx / Rx channels with which you can double the speed of the previous standard and thus offer the maximum performance on USB-C. Obviously, it will be backward compatible with all USB standards.
As mentioned, USB 3.2 will allow manufacturers to choose the type of coding to offer speed and its price. So we will have three options to choose from: USB 3.2 Gen 1 (5Gbps SuperSpeed), USB 3.2 Gen 2 (10Gbps SuperSpeed +) and USB 3.2 Gen2x2 (2x10Gbps SuperSpeed +).
