thunderbolt - Computer Definition
A peripheral interface from Intel that is based on Apple's Mini DisplayPort. First used in 2011 on a new line of MacBook Pro laptops, Thunderbolt provides simultaneous transfer of DisplayPort and PCI Express (PCIe) data. With dual bi-directional channels at 10 Gbps each, up to seven devices can be daisy chained together, including two high-resolution DisplayPort monitors. Adapters for DVI, HDMI and VGA are available. Thunderbolt 2 combines the two 10 Gbps channels into one, providing a single 20 Gbps bi-directional channel. Geared to HD Video Editing Thunderbolt was designed for high-speed video editing. For example, it enables multiple HD video streams to be read from a disk array, rendered on screen and transferred to an external HD monitor in real time. See PCI Express and DisplayPort.
