Thunderbolt 3

Thunderbolt 3 features and support

Thunderbolt 3 technology provides the fastest data and high-end video transfers over a single, versatile connector. While previous generations of Thunderbolt technology offered impressive transfer rates up to 20Gb/s bidirectional, Thunderbolt 3 doubles the potential up to 40Gb/s bidirectional when connected to other Thunderbolt 3 devices. In addition, Thunderbolt 3 gives priority to the video stream, apportioning the required bandwidth for playback. This is a critical advantage when working with high-end video and 3D graphics.

Thunderbolt 3 uses a USB-C connector specially labeled with a Thunderbolt icon. Since Thunderbolt 3 is protocol agnostic, it supports connections from the following interfaces:

• USB 2.0, USB 3.0 and USB 3.1
• DisplayPort 1.1 and 1.2a
• Thunderbolt 20Gb/s and Thunderbolt 40Gb/s
• Ethernet (with adapter)

Non-Thunderbolt 3 devices that feature USB-C ports can be connected to the Thunderbolt 3 port to terminate a daisy chain.
