USB 4 promises to support faster transfer speed, power delivery, and display interfaces.
The USB port technology is significantly proceeding ahead with the announcement of USB 4 by USB Promoter Group. Based on Intel’s Thunderbolt protocol, USB 4 supports 40 Gbps data transfer speed, power delivery, and display interfaces.
Let's find out what more differences USB 4 will make.
Currently, more than 50 companies are taking interest in the final stages of development of the USB4 specifications draft.
USB4 will be backward compatible with all the specifications of USB and Thunderbolt 3 enabled devices. It was least of a surprise that it would be compatible with older USB standards. Compatibility with Thunderbolt 3 devices will make all the expensive devices and cables to work in sync with each other.
USB 4 will support the 100W power charging speeds and the data transfer speed of 40 Gbps. It will carry enough bandwidth for one 5k display and 2 4k displays. If the users have a USB 3.x cable with Type-C connectors then they need to upgrade to USB 4 cables

In 2011, Intel partnered with Apple for the development of the Thunderbolt interface. It is made to assist the multiple protocols, quicker and more versatile interface.
Thunderbolt ports act as a USB port with Thunderbolt capabilities on focus. In other words, any device can be used with a Thunderbolt port. But it is not as easy as it looks; Thunderbolt ports won’t automatically become Thunderbolt devices. You will be restricted to USB 3.0 speeds if you use it with an external USB 3.0 hard drive.
Jason Ziller, General Manager, Client Connectivity Division at Intel, said,
“Releasing the Thunderbolt protocol specification is a significant milestone for making today’s simplest and most versatile port available to everyone.”
USB 4 official standard will reveal in the middle of 2019. We can expect the launch of USB in early 2020. But before you need to have the devices that support USB4 because without them you won’t be able to enjoy the benefits of USB 4 at maximum.
USB 4 will rule all the ports and the cable. USB Promoter Group is consists of the tech leading companies like Microsoft, HP, and Apple but Intel will come out as the main figure in the advancements of USB 4.
