Thunderbolt, formerly called ‘Lightpeak’, is Intel's new high-speed I/O technology through a single port that is first available on new Apple MacBook Pro notebooks lately. Fast data transfers are Intel's main claim, such as 10 gigabits per second transfers and dual-protocol support. The dual-channel design allows for two channels on the same connector at up to 10 gigabits per second that can support both PCI Express and DisplayPort technologies. Compared with existing technologies, Thunderbolt is regarded as a combination of HDMI and USB 3.0, the loading quantity is spectacularly huge through its co-invented PCI Express 4x, which can connect external devices directly to Macbook Pro.
