The new Mac Pro is already packed with power and performance but it's designed for even more. Smart design makes installing massice amounts of memory, adding expansion cards, and increasing storage surprisingly simple and intuitive. And there are plenty of I/O ports to connect external devices.

Start your engines. All eight of them.
Eight-core processing power was once only top-of-the-line. Now it comes standard. This time around, performance is more phenomenal than ever — up to two times faster than the previous standard-configuration Mac Pro. And with the multicore technology enhancements of Mac OS X Leopard, the new Mac Pro is a force to be reckoned with.

More power with less power.
Inside the new Mac Pro is the latest technology from Intel: Quad-Core Intel Xeon “Harpertown” processors. These processors run at blazingly fast speeds up to 3.2GHz. Based on the new 45-nm Intel Core microarchitecture, they deliver amazing performance but still maintain outstanding energy efficiency.

Built at full tilt.
With the fastest Xeon architecture available, the new Mac Pro features 1600MHz dual independent frontside buses. These 64-bit buses give each processor a direct connection to the system controller and deliver improved processor bandwidth of up to 25.6GB per second — 20 percent greater than the previous Mac Pro. With a new system architecture, speedier system buses, and fast 800MHz DDR2 fully buffered DIMM memory, Mac Pro memory throughput is up to 1.6 times faster than before.

Every Intel Xeon processor features an enhanced SSE4 SIMD engine. Capable of completing 128-bit vector computations in a single cycle, SSE4 is ideal for transforming large sets of data, such as applying a filter to an image or rendering a video effect.

Smarter memory.
The Mac Pro incorporates a 256-bit-wide, fully buffered memory architecture with Error Correction Code (ECC), which corrects single-bit errors and detects multiple-bit errors automatically. These features are especially important in mission-critical or compute-intensive environments. Apple designed a more stringent thermal speci?cation for the Mac Pro FB-DIMMs, so the internal fans spin at slower speeds and keep the system quiet.

Feast your eyes.
All-new high-performance graphics cards from ATI and NVIDIA make Mac Pro graphics technology even more cutting edge. The standard graphics card — an ATI Radeon HD 2600 XT with 256MB of GDDR3 memory, PCI Express 2.0, and two dual-link DVI ports — provides great performance for typical creative applications. And you get dual 30-inch Apple Cinema HD Display support out of the box.

For motion graphics, 3D modeling, rendering, or animation, youll need the greater graphics horsepower offered by the NVIDIA GeForce 8800 GT with 512MB of GDDR3 memory and latest-generation NVIDIA GPU technology.

The optional NVIDIA Quadro FX 5600 graphics card is the ultimate workstation-class graphics card available, with a massive 1.5GB of GDDR3 memory and a 3D stereo port for stereo-in-a-window applications.

All of these cards feature the latest-generation unified shader model support. Compared to dedicated pixel and vertex shaders, shaders are no longer special-purpose and can now be utilized based on the needs of the graphics application.

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. 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.

Ready to RAID.
Using Mac OS X, you can stripe two, three, or all four hard drives in a RAID 0 array to increase performance and create a massive volume for video editing; or create a RAID 1 mirror for protecting your critical digital media assets against a drive failure. For the ultimate in data protection and enhanced performance, add the optional Mac Pro RAID Card with 256MB of RAID cache, a 72-hour cache-protecting battery, and hardware RAID levels 0, 1, 5, and 0+1. Apples RAID Utility software makes setting up and managing the RAID card easy.

Double-layer burner, times two.
Sure its great to have one 16x SuperDrive at your disposal, but think how much more productive you could be with two. Imagine backing up your data to two double-layer DVDs at once. Or burning Aperture projects to one DVD, while importing music from a CD into your iTunes library. With two optical drive bays in every system, the Mac Pro lets you do exactly that.

64-bit power.
Leopard is the first universal operating system to seamlessly support both 64-bit and 32-bit applications. Theres no need to upgrade drivers, and you can even stick with your existing printers, storage devices, and PCI Express cards. Leopard lets you take advantage of 64-bit processing power without having to use command-line applications, servers, and computation engines.

UNIX compliant.
What makes Leopard so great? The fully compliant UNIX technology. It can compile and run all your existing UNIX code. It helps you make the most of multicore systems. It puts a new tabbed-interface terminal at your fingertips. And it gives Leopard the solid groundwork for hundreds of great new features on every Mac Pro.

Multicore. Multithreaded.
Leopard is designed to take full advantage of eight cores of processing power. The new Leopard scheduler allocates tasks more efficiently across these multiple cores and processors. A new multithreaded network stack speeds up networking. And Mail, Address Book, and Font Utility have all been updated to be fully multicore ready.
