Thunderbolt

A peripheral interface from Intel introduced in 2011. First used on a MacBook Pro laptop, Thunderbolt provides simultaneous transfer of DisplayPort graphics for the monitor and PCI Express data for storage and other devices. Thunderbolt 3 added USB 3.1 Gen 2 connectivity.

Up to six peripherals can be connected in a daisy chain, providing an expansive external interface over one port. However, computers generally have several Thunderbolt ports. See DisplayPort, PCI Express and USB.

Thunderbolt 4
In 2020, Thunderbolt 4 is expected to have the same speed as Thunderbolt 3 but also support USB 4. Following are the Thunderbolt generations, and each is backward compatible with the previous one. See Thunderbolt Display and Thunderbolt Bridge.

Mini DisplayPort (mDP)
Thunderbolt 1 and 2 use the Mini DisplayPort plug and socket; however, Thunderbolt 3 switched to USB-C (see USB Type C).







Thunderbolt on a Desktop Mac
Two of the six Thunderbolt ports are used on this 2nd-generation Mac Pro. The black cable delivers DisplayPort to the monitor, and the orange cable transfers data between an external drive over PCI Express. See Mac Pro.
