Intel's Xeon Clovertown series is the firm's highest performance commercial processor.
The chips were first demonstrated by Intel chief executive Paul Otellini at IDC in August and perform up to 80 per cent faster than dual-core chips, according to the firm.
The new Mac Pros feature two Xeon 5300 quad-core chips running at 3GHz, as well as the capacity for up to 3TB of hard drive storage and 16GB of Ram. Users can choose between ATI or nVidia graphics cards.
Apple positions the quad-core systems as high-end workstations for the professional market. Retail prices start at $3,997. The vendor will keep selling its current line of dual-core Xeon Mac Pro systems.
The quad-core announcement comes at an opportune time for high-end users seeking to upgrade their Macs.
