Next-generation Intel architecture.
With four cores on one die and an integrated memory controller, the new Quad-Core Intel Xeon “Nehalem” processor boosts performance nearly 2x.

Memory bottlenecks begone.
System memory is often connected to a processor through a separate I/O controller. But each Intel Xeon “Nehalem” processor features an integrated memory controller — another leap forward for workstation system architecture. By connecting memory directly to the processor, the new Mac Pro processors have faster access to data stored in memory, and memory latency is reduced by up to 40 percent.

Expansion made easy.
The redesigned interior of the new Mac Pro feels like the well-organized 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.

Faster, more flexible graphics.
Powerful AMD and NVIDIA graphics cards provide the fastest-ever Mac graphics, while a new Mini DisplayPort gives you more display options

Power when (and where) you need it.
The new Mac Pro introduces Turbo Boost: a dynamic performance technology that automatically boosts the processor clock speed based on workload. If you’re using an application that doesn’t need every core, Turbo Boost shuts off the idle cores while simultaneously increasing the speed of the active ones, up to 3.33GHz on a 2.93GHz Mac Pro.

The virtue of virtual cores.
The new Intel Xeon “Nehalem” processors support Hyper-Threading, which allows two threads to run simultaneously on each core. So an 8-core Mac Pro presents 16 virtual cores that are recognized by Mac OS X. Performance is enhanced because Hyper-Threading enables the processor to take better advantage of the execution resources available in each core.

Path of least resistance.
A new bidirectional, point-to-point connection — called QuickPath Interconnect — gives the Intel Xeon “Nehalem” processor quick access to the disk, I/O, and other Mac Pro subsystems. In the new 8-core Mac Pro, there’s a QuickPath Interconnect between the two quad-core processors as well. This connection acts as a direct pipeline, so processor-to-processor data doesn’t need to travel to the I/O hub first. It’s another way the new Mac Pro boosts performance across the board.

Powerfully efficient.
Based on an industry-leading 45-nm process technology and combined with improved power management capabilities, the new Intel Xeon “Nehalem” processors are more energy efficient than before. So the Mac Pro is faster than ever, while using less energy when idle.
