Features:
* 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 8MBof 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
* Memory bottlenecks begone. System memory is often connectedto 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 storedin memory, and memory latency is reduced by up to40 percent.
* 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 whilesimultaneously increasing the speed of the activeones, up to 3.33GHz on a 2.93GHz Mac Pro.
* Thevirtue 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 Interconnectbetween 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 theI/O hub first. It’s another way the new Mac Pro boosts performance across the board.
