USB version 4 is on the way, offering double the fastest possible USB data transfer rate over the previous generation: a satisfying 40Gbps.

On Monday, the USB Promoter Group announced the new spec is ready to be revealed, just a week after details of the latest iteration of the current standard – USB 3.2 – was released.

Note - USB - Communications - Data - Lines

Note, we're talking about USB communications here: how the data is transferred over the lines, not the physical plugs and sockets. This announcement means future devices and computers can use USB4 to shove files and other information between each other much faster, typically via physical USB-C connectors.

USB4 – yes, no space – is based on Intel's Thunderbolt 3 specifications, and will allow for multiple simultaneous data and display linkages, meaning that you can use it for several different devices at the same time, and each data transfer will be adjusted dynamically between each bit of kit.

Backwards - USB - Thunderbolt - Specs - USB

Critically, it will be backwards compatible with existing USB 2, 3 and Thunderbolt 3 specs. Because it's a USB specification, it will also be an open standard and royalty-free. This follows from Intel's promise to make Thunderbolt 3 royalty free. The chip giant will continue to tout its Thunderbolt tech until USB4 becomes a reality.

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

Spec - Middle - Year - Time - Release

The spec will be formally published in the middle of the year, around the same time as the release of USB 3.2 kit. That means that USB4 should become available in products...
