USB4 will offer up to 40GB/s transfer speeds, improved power and support for new display protocols, the USB Implementation Forum has announced.
The new USB4 standard will use the same Type-C connection and the first devices using it will come to market next year.
What’s more, USB4 will be backward compatible with USB 3.2 and USB 2.0. USB4 will also incorporate Intel’s Thunderbolt 3 technology, which is used in Apple MacBooks, opening it up to wider use.
This should also make accessories more accessible. From the announcement:
USB4 should help with a better to juggle lots of different data streams – multiplexing in industry terms – so you can plug multiple USB-C devices into a single hub.
Anyone building USB4 devices also must include the USB Power Delivery technology, which controls how devices negotiate charging and enables much higher charging rates for power-hungry devices like laptops.
