Intel Thunderbolt I/O Controllers

Intel's Thunderbolt I/O Controller technology is a transformational high-speed, dual protocol I/O that provides unmatched performance over current I/O technologies with 10Gbps bi-directional transfer speeds. It provides flexibility and simplicity by supporting both data (PCIe) and video (DisplayPort) on a single cable connection that can daisy-chain up to six devices. Thunderbolt technology enables flexible and innovative system designs and is ideal for thin profile systems and devices such as Ultrabooks. Thunderbolt technology dramatically increases the data transfer rate enabling faster backup, editing and file sharing, significantly reducing the time to complete key tasks. Thunderbolt technology was specifically designed with inherently low latency and highly accurate time synchronization capabilities. These features enable extremely accurate audio and video creation, playback and editing that no other standard interconnect technology can match.
