USB 4 2.0 is a new version of the USB standard that offers a number of improvements over USB 4. The main improvements are the increased data transfer rates and improved compatibility. USB 4 2.0 is not yet widely used, but it is expected to be used in more devices in the next few years.

Increased data transfer rates

The maximum data transfer rate of USB 4 2.0 is 120 Gbit/s, which is equivalent to 15 GB/s. This is twice as fast as the maximum data transfer rate of USB 4, which is 40 Gbit/s.

The increased data transfer rates of USB 4 2.0 allow larger amounts of data to be transferred more quickly. This is useful, for example, for transferring 8K video, 3D models or large files such as videos or photos.

Improved compatibility

USB 4 2.0 is backwards compatible with older USB standards, including USB 3.2, USB 3.1 and USB 3.0. This means you can continue to use older USB devices with newer computers that support USB 4 2.0 ports.

New function

USB 4 2.0 supports new features such as Power Delivery 3.1 and Alternate Mode.

• PowerDelivery 3.1: Power Delivery 3.1 enables a power output of up to 100 watts via a single cable. This is enough to power a laptop, for example.
• Alternate Mode: Alternate Mode allows you to control USB devices via DisplayPort or Thunderbolt 3. This means that you can, for example, connect a monitor or external storage via a USB port.
