Next-generation Intel architecture.
Get nearly 2x faster performance with the new Mac Pro, now powered by all-new Quad-Core Intel Xeon ?Nehalem? processors. With a new system architecture, 8MB of fully shared L3 cache, an integrated memory controller, and 1066MHz DDR3 ECC memory, these processors deliver up to 2.4x greater memory bandwidth. And new Turbo Boost technology speeds up the processor when all cores aren?t in use.

The ?Nehalem? advantage.
Many quad-core processors are composed of two separate dies, which means some cached data has to travel outside the processor to get from core to core. That?s an inefficient way to access information. Enter the Quad-Core Intel Xeon ?Nehalem? processor. Its single-die, 64-bit architecture makes 8MB of fully shared L3 cache readily available to each of the four processor cores. The result is fast access to cache data and greater application performance. Combine that with the other technological advances and you get a Mac Pro that?s up to 1.9x faster than the previous generation.

Expansion made easy.
The redesigned interior of the new Mac Pro feels like the well-organised workstation it is. No rat?s nest of components here. You don?t need to turn the system on its side or struggle to reach into awkward spaces to make changes. Just remove the side panel for instant, easy access to everything. Slide out the processor tray to add memory. Slide out hard drive bays to add storage. Slide a simple bar to change up to four expansion cards at once. And with plenty of I/O ports both front and back, you?ll have room for all your external devices.

Don?t keep those pixels waiting.
If you?re a pro who wants a desktop computer that keeps pace with your imagination, the Mac Pro delivers with faster graphics application performance across the board. Whether you?re decoding H.264 content in Final Cut Pro, creating 3D graphics in Motion, processing massive RAW images in Aperture or playing the latest games, the graphics hardware in the new Mac Pro makes graphics applications faster.

The foundation of this new graphics architecture is the latest generation of GPUs connected to the system via a fast and wide PCI Express 2.0 16-lane bus. Couple that with Core Animation, Core Image and Core Video technologies in Mac OS X Leopard. The result is a graphics platform for applications to seamlessly tap into a teraflop of graphics power

Massive storage.
The Mac Pro comes with four 3.5-inch internal hard drive bays for an enormous amount of internal storage ? up to 4TB when you install four 1TB Serial ATA 3Gb/s drives.1 Each bay provides its own independent 3Gb/s channel for fast access to data. And thanks to the cable-free, direct-attach installation system, adding (or replacing) hard drives is a surprisingly simple process.

More energy efficient.
Even though the Mac Pro is the fastest Mac ever, nearly 2x faster than before,1 it is also more energy efficient. The energy-efficient hardware components in the Mac Pro work hand in hand with Mac OS X to create a system that can dynamically adjust power consumption to reduce the overall energy used. For instance, the CPU architecture allows individual cores to go into a low-power state to reduce energy consumption when they are not needed. The graphics card does the same, reducing power draw when not running graphics-intensive applications. The result is a smarter and more energy-efficient system that is not only as fast as possible when you need it, but also throttles down power use when it?s not needed. Compared with the previous-generation Mac Pro, the power used when the system is idle has been reduced by 15 percent.
