Thunderbolt technology is a new, high-speed, dual-protocol I/O technology designed for performance, simplicity, and flexibility which is developed by Intel with the code name Light Peak and brought to market with technical collaboration from Apple.


  • Dual-channel 10 Gbps per port
  • Bi-directional
  • Dual-protocol (PCI Express* and Display Port*)
  • Compatible with existing Display Port devices
  • Daisy-chained devices
  • Electrical or optical cables
  • Low latency with highly accurate time synchronization
  • Uses native protocol software drivers
  • Power over cable for bus-powered devices.

Thunderbolt technology enables using the thinnest and lightest laptops and connecting to the extra power and performance of other devices when needed, using a single cable. Adding new performance devices is simple and easy—just plug and play—making Thunderbolt technology powerful and flexible.

Data transfers for backup, sharing, and editing are tremendously accelerated using Thunderbolt products, significantly reducing times to complete these tasks.

And Thunderbolt enabled products are compatible with existing Display Port devices so you don’t have to go buy a new display to take advantage of a Thunderbolt technology enabled computer.

Intel’s Thunderbolt controllers interconnect a PC and other devices, transmitting and receiving packetized traffic for both PCIe and Display Port protocols. Thunderbolt technology works on data streams in both directions, at the same time, so users get the benefit of full bandwidth in both directions, over a single cable. With the two independent channels, a full 10 Gbps of bandwidth can be provided for the first device, as well as additional downstream devices.
