USB 4 Version 2.0 is twice as fast as Thunderbolt 4 and USB 4; while still supporting cable set-up

The USB Promoter Group announced USB 4 Version 2.0, which is twice as fast as Thunderbolt 4 and USB 4. Its full list of technical specs will be released in November.

The new USB 4 Version 2.0 is now official. It will be a big step forward in terms of technology compared to the current version. The USB Promoter Group said that the new specification are coming soon. It will allow a USB-C cable and connector to transfer data at speeds of up to 80 Gbps.

This is a big change because it’s twice as fast as the original USB 4 and Thunderbolt. These devices released in recent years. But the full list of technical features won’t be made public until November, before the USB DevDays events.

Outside of the details, there is a very important fact that shouldn’t be missed. A new physical layer architecture will be used for USB 4 Version 2.0 so that it can support data transfer rates of up to 80 Gbps. It will use newer, faster active USB-C cables, but it will also work with the 40Gbps passive USB-C cables that are already in use.

As expected, the new USB 4 will keep a lot of the same features as its predecessors. With USB 4 version 1.0, USB 3.2, USB 2.0, and Thunderbolt 3.

With the release of USB 4 Version 2.0, it will be easier to use DisplayPort and PCI Express. However, it will require the latest version of each. The creators of the USB 3.2 specification say that it will be updated to improve performance and be able to go faster than 20 Gbps. The USB Power Delivery standard will also be made better.

New USB 4 Version 2.0 will be revolutionary

No one knows yet when the public will be able to use the new USB 4 Version 2.0. From the USB Promoter Group, they said that this specification will be for developers for the time being. There has also been no set date for when USB 80 Gbps-labeled certified cables and products will start to show up. Though it has been said that this will happen “in the future.”

Without a doubt, this will be a huge step forward for many devices that use USB-C. Storage drives, like removable disks, will benefit a lot from the start if they can send large files quicker. For example, content creators who are working with 4K or 8K video will move it easily from one computer to another. Any type of professional user is the same.

Not to mention gamers and other people who use screens with high resolutions and refresh rates every day. And let’s not forget about the docks and hubs, which also play a crucial role.

The president of the group, Brad Saunders, was very excited about this launch. “Once again, in the USB tradition, this updated USB 4 specs doubles the speed of data transfer to make the USB-C ecosystem more useful,” he said.

For now, we have to wait a little longer to fully understand the news about the new USB 4 Version 2.0. This year’s USB DevDays will be held on November 1 and 2 in Seattle, United States, and on November 15 and 16 in Seoul, South Korea.
