Thunderbolt 1 (10 Gb/s) and Thunderbolt 2 (20 Gb/s) changed this concept by creating a super fast pipe that broke PCI Express out of its confines and into external devices while supporting DisplayPort video over the same Mini DisplayPort connector. Historically, computer's internal interfaces like PCI Express tended to be faster than external interfaces like USB and DisplayPort. Thunderbolt provides the highest performance data rates available to consumers, enabling you to do faster reads and writes to storage devices, connect to 10G networks, enhance graphics performance by connecting to external graphics cards, and access docks and 4K displays with a wide array of interface port expansion options.

Thunderbolt is a technology developed by Intel that enables consumers to do more with their Windows and Mac based computers.
