The USB Promoter Group, the organisation that takes care of all things related to the USB data transfer protocol, has announced the features we're likely to see in the next iteration.

USB 4 is based upon Intel's Thunderbolt tech and promises to double the current data speeds and enable simultaneous data and display transfers.

"The primary goal of USB is to deliver the best user experience combining data, display and power delivery over a user-friendly and robust cable and connector solution," said Brad Saunders, USB Promoter Group chairman.

"The USB4 solution specifically tailors bus operation to further enhance this experience by optimising the blend of data and display over a single connection and enabling the further doubling of performance."

It will use the same USB C connector with the headline aspects only visible under the hood.

Users can expect information to be transferred at rates of 40Gbps, providing they're using a cable that supports it, which is a pretty big jump up from USB 3.2's ceiling.

Thankfully, it'll be backwards compatible with USB 3.2, USB 2.0 and Thunderbolt 3, meaning users won't need to buy all-new USB 4 devices and peripheries.

"Releasing the Thunderbolt protocol specification is a significant milestone for making today's simplest and most versatile port available to everyone," added Jason Ziller, general manager of Intel's client connectivity division.

"By collaborating with the USB Promoter Group, we're opening the doors for innovation across a wide range of devices and increasing compatibility to deliver better experiences to consumers."
