Apple Mac Pro



Accelerated architecture.

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.1

Mac Pro architecture

Memory bottlenecks be gone.

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.2 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.

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 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.

Path of least resistance.

A new bi-directional, 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.

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.

The fastest Mac graphics ever.

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.

Performance. It’s in the cards.

All-new high-performance graphics cards from AMD and NVIDIA make Mac Pro graphics technology faster than before. Perfect for motion graphics, 3D modeling, rendering, or animation, the NVIDIA GeForce GT 120 with 512MB of GDDR3 memory comes standard — and provides up to 2.9x the performance of previous Mac Pro standard graphics cards.1

For even more graphics horsepower, upgrade to the ATI Radeon HD 4870 with 512MB of GDDR5 memory. An ideal choice for the most demanding applications, this card features a wider memory bus and higher-performance GPU, resulting in up to 2x faster performance compared with the NVIDIA GeForce GT 120.1

Store more.
Up to 4TB 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.

Ready to RAID — with a new card.

For the ultimate in data protection and enhanced performance, add the new Mac Pro RAID Card with 512MB of RAID cache, a 72-hour cache-protecting battery, and hardware RAID levels 0, 1, 5, and 0+1. A new cableless connection and intuitive Apple software make it a snap to install this optional card. Once installed, high-performance 15,000-rpm SAS drives may be used. It’s the perfect solution for workgroup servers, video pros working with high-bit-rate assets, or anyone who wants to protect critical data.

Even without a RAID card, Mac OS X lets you stripe two, three, or all four hard drives in a RAID 0 array to increase performance and create a massive volume for tasks such as video editing; or create a RAID 1 mirror to protect digital media assets from a drive failure.

Mac Pro optial drives
Double-layer burner times two.

Sure it’s great to have one 18x 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.

Systems were configured with 6GB of RAM for Mac Pro 8-core 2.93GHz and 8GB of RAM for Mac Pro 8-core 3.2GHz. Tested using Call of Duty 4 v1.7.1, Timedemoambush, Timedemobog, Timedemopipeline, maximum graphics quality, 4x anti-aliasing, at 1680x1050. Performance tests are conducted using specific computer systems and reflect the approximate performance of Mac Pro.
