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’s on MacBook Air, MacBook Pro, iMac, and
Mac mini.
Powerful technology from a powerful collaboration.
Thunderbolt began at Intel Labs with a simple concept: create an incredibly fast input/output technology that just about anything can
plug into. After close technical collaboration between Intel and Apple, Thunderbolt emerged from the lab to make its appearance in
Mac computers.
Intel co-invented USB and PCI Express, which have become widely adopted technologies for data transfer. Apple invented FireWire
and was instrumental in popularizing USB. Their collective experience has made Thunderbolt the most powerful, most flexible I/O
technology ever in a personal computer.
One small port. One giant leap in possibilities.
MacBook Air, MacBook Pro, iMac, and Mac mini now give you access to a world of high-speed
peripherals and high-resolution displays 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 your Mac — and get PCI Express performance. That’s a first for any
computer. Thunderbolt also provides 10 watts of power to peripherals, so you can tackle
workstation-class projects. With PCI Express technology, you can use existing USB and FireWire
peripherals — even connect to Gigabit Ethernet and Fibre Channel networks — using simple
adapters.
All that power and blazing-fast data transfer flows through the Apple Thunderbolt Cable, one of
the most advanced cables ever made. No single cable has been able to do so many things and
do them with such astonishing speed. It doesn’t just connect high-performance devices. It is one
in its own right.
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 and expansion made faster and smarter.
Thunderbolt I/O technology gives you two channels on the same connector with 10 Gbps of throughput in both directions. That
makes Thunderbolt ultrafast and ultraflexible. You can move data to and from peripherals up to 20 times faster than with USB 2.0
and up to 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 display to a single Thunderbolt chain while maintaining maximum throughput.

High performance on display.
Thunderbolt I/O technology provides native support
for the Apple Thunderbolt Display and Mini
DisplayPort displays. It also supports DisplayPort,
DVI, HDMI, and VGA displays through the use of
existing adapters. So you can connect your Apple
LED Cinema Display or other display, along with
multiple high-speed devices, all from a single port.
No project is too massive.
With Thunderbolt, you’re just as likely to build a professional video setup
around your MacBook Pro or iMac as your Mac Pro. If you’re a video
editor, imagine using a single port to connect high-performance storage,
a high-resolution display, and high-bit-rate video capture devices to
handle all the post-production for a feature film. Thunderbolt I/O
technology allows you to daisy-chain up to six Thunderbolt peripherals,
including an Apple Thunderbolt Display and the Promise Pegasus RAID
or LaCie Little Big Disk.1 You can even add an Apple LED Cinema
Display to the end of the chain.
And that’s just the beginning. With Thunderbolt
technology, peripheral manufacturers finally
have what they need to take high-performance
devices from workstations and top-of-the-line
desktops to just about any computer.
