The new Mac Pro - Beauty outside. Beast inside...
With four cores on one die and an integrated memory controller, the new Quad-Core Intel Xeon Nehalem processor boosts performance nearly 2x. Powerful AMD or NVIDIA graphics cards provide the fastest-ever Mac graphics, while a new Mini DisplayPort gives you more display options. And 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.
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.
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.
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 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.
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.
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.
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 Snow Leopard. The result is a graphics platform for applications to seamlessly tap into a teraflop of graphics power.
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.
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
Every new Mac Pro graphics card features two display ports for maximum workspace flexibility. A Mini DisplayPort connects the new 24-inch Apple LED Cinema Display with ease. A dual-link DVI port connects a 30-inch Apple Cinema HD Display or any other DVI display. And with support for up to four NVIDIA GeForce GT 120 cards, you can connect more displays up to eight total.
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.
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.
