Apple Mac Pro tower 8 Core with 2x 2.26GHz Quad-Core Intel Zeon Nehalem processor, 6GB of Ram (6x 1GB), 640GB Hard Drive and a GeForce GT120 Graphics Card with 512MB Ram and a 18x Double-Layer Super Drive. The Mac pro now features four cores on one die and an integrated memory controller with the result of the new Quad-Core Intel Xeon 'Nehalem' processor boosting performance by nearly 2x. A completely new interior makes it even easier to add up to 32GB of memory, four PCI Express expansion cards and up to 4TB of hard drive storage. Powerful AMD and NVIDIA graphics cards provide the fastest-ever Mac graphics, while a new Mini DisplayPort gives you more display options.
Apple Mac Pro - 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.
Apple Mac Pro - Faster, more flexible graphics.
The new Mac Pro features the fastest graphics ever on a Mac. Its standard configuration includes the up to 2.9x faster NVIDIA GeForce GT 120 with 512MB of GDDR3 memory. For even greater performance — up to 2x more — upgrade to the ATI Radeon HD 4870.
Apple Mac Pro - Flexible display options.
With a Mini DisplayPort and dual-link DVI port on every graphics card and room for up to four cards, the new Mac Pro provides dozens of display options.
Apple Mac Pro - Easier expansion.
A completely redesigned interior makes it even easier to access and upgrade your Mac Pro. Snap in up to 32GB of memory. Pop in up to four PCI Express 2.0 expansion cards. Slide in up to 4TB of storage. Add in the new, easier-to-install Mac Pro RAID Card. All without turning the system over or struggling with tight spaces.
Apple Mac Pro - 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.
Apple Mac Pro - 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.
The integrated memory controller, along with fast 1066MHz DDR3 ECC SDRAM, also gives Mac Pro up to a 2.4x increase in memory bandwidth over previous generations. More bandwidth allows for more data to be fed to the processor faster, helping each core spend its time processing data, not waiting for information to arrive. And Error Correction Code (ECC) corrects single-bit errors and detects multiple-bit errors automatically. That’s especially important in mission-critical and compute-intensive environments.
Apple Mac Pro - 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.
Apple 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 recognised 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.
Apple Mac Pro - 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.
Apple Mac Pro - 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.
