We are almost two years away from announcing the USB 3.2 specification, which ended up delaying its deployment due to the delay in the launch of the USB-C. Today during the MWC 2019 , the USB Implementers Forum (USB-IF) finally confirmed that everything is ready for the arrival this same 2019 of the new USB 3.2 standard .
The USB-IF mentioned that the drivers to add support to USB 3.2 will be published in the coming days, this with the aim of manufacturers to incorporate them into their devices before the end of the year. Therefore, the first PCs with USB 3.2 support should arrive at the end of the year .
It is believed that the first compatible peripherals will arrive in 2020
Although USB 3.2 is a punctual update, the reality is that little by little is closer to Thunderbolt 3 and its 40Gbps, and that USB 3.2 will be able to offer speeds of up to 20Gbps over USB-C .
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 of this new USB 3.2 standard, it is highlighted that it will allow to use two Tx / Rx channels (the so-called ‘x2 mode’) with which you can double the speed of the previous standard and thus offer the maximum performance , always on USB-C. Obviously it will be backward compatible with all USB standards and will keep all USB support and compatibility 3.x.
As mentioned, USB 3.2 will allow manufacturers to choose the type of coding to offer the speed that best suits their needs, and 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 +) . Although this double channel linkage is new, the way in which they work individually is not, since right now we have it in the specifications USB 3.1 Gen 1 (5 Gbps), as in USB 3.1 Gen 2 (10 Gbps).
