The USB Promoter Group has been collaborating with Intel in order to release the USB 4.0 standard based on the USB-C interface with Thunderbolt 3 support. The new USB ports will enable data transfer speeds of up to 40 Gbps and will provide support for multiple data and display protocols, as well as advanced power delivery features for fast charging devices.

A little over a week ago, the USB Implementers’ Forum was announcing the USB 3.2 specs and the new, arguably confusing, naming scheme for the 3.x family. However, with Intel announcing extended support for the Thunderbolt 3 interface on the upcoming Ice Lake CPUs and releasing the specs for increased adoption, the upcoming USB 4.0 standard is set to get a significant speed boost that matches the latest Thunderbolt 3 iteration.

The USB Promoter Group has just announced an overview of the upcoming USB 4.0 standard, while the full specs are scheduled to be ratified some time in mid-2019, so consumer products integrating the new connectors should arrive in 2H 2019 together with Intel’s Ice Lake platform. All USB 4.0 connectors will be based on the current USB-C ports with Thunderbolt support and they will be backwards-compatible with the older USB 2.0/3.x and Thunderbolt 3 interfaces. Just like Thunderbolt 3 and HDMI 2.1, USB 4.0 will feature transfer speeds of up to 40 Gbps and will support multiple data and display protocols like Display Port 1.4, plus advanced power delivery for devices that support fast charging.

Over 50 companies are now actively supporting the adoption of the USB 4.0 standard, and the full specs should be detailed at this year’s USB Developer Days in September.

I stepped into the wonderous IT&C world when I was around 7. I was instantly fascinated by computerized graphics, be them from games or 3D applications like 3D Max. I like to keep myself up to date with all the new technologies that get released at an ever increasing rate these days. I'm also an avid SciFi reader, an astrophysics aficionado and, as of late, a crypto geek.
