Apple has refreshed its MacBook Pro lineup with next-gen Intel processors (dual-core/quad-core) and graphics, high-speed Thunderbolt I/O tech and a new Facetime HD camera. So, what is Thunderbolt I/O?
Well, as senior Apple VP Phillip Schiller explains, Thunderbolt is a "revolutionary" new technology capable of delivering 10 gigabits per second, while supporting "every important" I/O standard.
According to Schiller, the advanced protocol - which was developed by Intel with collaboration from Apple - offers two bi-directional channels with transfer speeds up to 10Gbps each and delivers PCI Express directly to external high performance peripherals such as RAID arrays.
Thunderbolt I/O also supports FireWire, USB consumer devices, Gigabit Ethernet networks via adapters and DisplayPort for high resolution displays.
In addition, the new protocol works with existing adapters for HDMI, DVI and VGA displays.
