Intel Thunderbolt Technology: An Overview

Intel is changing the way the world computes once again. In development for years and now available to the public, the chip manufacturer's new Thunderbolt technology enables multiple devices and peripherals to communicate at enhanced speeds. The new technology is to arrive on devices this year, and is being regarded as becoming the successor to USB, FireWire, and DisplayPort technologies.

During recent years there have been significant technological communication enhancements that have changed the way computers are used. The move from analog dialup to digital broadband, serial to USB, and the introduction of FireWire are just a few popular examples. Now, new from Intel, is their long awaited high speed communications technology formally known in development as Light Peak. The newly named Thunderbolt technology allows for peripherals to reportedly carry data and video at 10 gigabits per second. Additionally, the high-speed data and display transfer medium has the included benefit of working in each direction, at the same time.

While upcoming early adopters of the technology include Promise Technology, Inc. and LaCie, Apple users should be glad to know that not only do the new 2011 line of MacBook Pros feature Intel's latest and greatest Sandy Bridge CPUs, but also include Thunderbolt technology built-in. The new communications port found on the portables appear identical to existing DisplayPort connections, are backwards compatible, and with an optional adapter will interface with HDMI devices. Interstingly, Thunderbolt is has been publicly announced as being developed by Intel, and brought to market with technical collaboration from Apple.

Listed features for Thunderbolt include dual-channel 10 Gbps per port, bi-directional communication, dual-protocol (through PCI Express and DisplayPort), daisy-chaining of devices, the use of native device drivers, and power over cable for bus-powered devices . Amongst a wealth of additional technical data at the Thunderbolt website, Intel has benchmarked the 10 Gbps performance with the ability to transfer (via high speed storage) a typical full-length 1080p HD movie with a file size of 10-20 GB in less than 30 seconds, and the ability to backup 1 year of continuous MP3 playback in about 10 minutes

As the availability of multiple protocols possible on a single wire is one of Thunderbolt's popular features, long term benefits would also include a redesign and reduction in hardware form factors. As port consolidation becomes a potential option, slimmer hardware and easier methods of cable management should follow.
