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.
