Apple Mac Pro Quad-Core

QuickPath Interconnect is a bidirectional, point-to-point connection giving the processors quick access to the disk, I/O and other subsystems, which boosts the performance accross the board. While this is one of the most powerful Macs to date(next to the 8-core), the advancements in power management allow it to run on less energy when idle making this a powerfull, and energy efficient machine.
