Introducing the new Mac Pro, featuring the Intel Xeon "Nehalem" processor.

Introducing the all-new Mac Pro. It's nearly twice as powerful, thanks to the next-generation Quad-Core Intel Xeon "Nehalem" processors and new system architecture. Each processor features an integrated memory controller, three channels of 1066MHz DDR3 ECC memory, 8MB of fully shared L3 cache, and Turbo Boost and Hyper-Threading technologies. The result? The fastest Mac ever.

The NVIDIA GeForce GT 120 graphics processor with 512MB of GDDR3 memory provides up to 2.9x the performance of previous Mac Pro standard graphics cards. For even more graphics power, the optional ATI Radeon HD 4870 with 512MB of GDDR5 memory is up to 2x faster than the GeForce GT 120. With the new Mini DisplayPort and dual-link DVI port, you can connect a 24-inch Apple LED Cinema Display and a 30-inch Apple Cinema HD Display. The entirely redesigned Mac Pro interior makes it even easier to add and remove memory, expansion cards, and hard drives. The Mac Pro also features massive storage and expansion options: up to eight DIMM slots for up to 32GB of memory, four cable-free direct-attach hard drive bays for up to 4TB of storage, and four PCI Express 2.0 expansion slots. An all-new optional Mac Pro RAID Card brings data protection and increased hard drive performance. Front and rear FireWire 800 and USB 2.0 ports make it easier to connect external devices. It! ?s the most advanced Mac Pro ever.
