Developed by Intel (under the code name Light Peak), and brought to market with technical collaboration from Apple. Thunderbolt technology is a new, high-speed, dual-protocol I/O technology designed for performance, simplicity, and flexibility. This high-speed data transfer technology features the following:
- Dual-channel 10 Gbps per port
- Bi-directional
- Dual-protocol (PCI Express* and DisplayPort*)
- Compatible with existing DisplayPort 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
Intel’s Thunderbolt controllers interconnect a PC and other devices, transmitting and receiving packetized traffic for both PCIe and DisplayPort 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. More info Click here.
Thunderbolt is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices through a single, compact port. It sets new standards for speed, flexibility, and simplicity. And it makes its debut in the new MacBook Pro. MacBook Pro now gives you access to a world of high-resolution displays and high-speed peripherals with one compact port. That’s because Thunderbolt is based on two fundamental technologies: PCI Express and DisplayPort. PCI Express is the technology that links all the high-performance components in a Mac. And it’s built into Thunderbolt. Which means you can connect external devices like RAID arrays and video capture solutions directly to MacBook Pro — and get PCI Express performance. That’s a first for notebooks. Thunderbolt also provides 10 watts of power to peripherals, so you can tackle workstation-class projects on the go. With PCI Express technology, you can use existing USB and FireWire peripherals — even connect to Gigabit Ethernet and Fibre Channel networks — using simple adapters. And because Thunderbolt is based on DisplayPort technology, the video standard for high-resolution displays, any Mini DisplayPort display plugs right into the Thunderbolt port. To connect a DisplayPort, DVI, HDMI, or VGA display, just use an existing adapter.
PERFORMANCE: Thunderbolt I/O technology gives you two channels on the same connector with 10 Gbps of throughput in both directions. That makes it ultrafast, and ultraflexible. You can move data to and from peripherals up to 20 times faster than with USB 2.0 and more than 12 times faster than with FireWire 800. You also have more than enough bandwidth to daisy-chain multiple high-speed devices, without using a hub or switch. For example, you can connect several high-performance external disks, a video capture device, and even a Mini DisplayPort display to a single Thunderbolt chain while maintaining maximum throughput.
