Mac Pro

The Quad-Core Intel Xeon processor in the Mac Pro is based on the next-generation Intel Core microarchitecture, also known as Nehalem, and includes the following features:

* 8MB of fully shared L3 cache per processor, which boosts performance by keeping data and instructions in a fast-access cache that is available to all four processor cores.
* An integrated memory controller, which allows faster access to data stored in memory by significantly increasing memory bandwidth and reducing memory latency by up to 40%.
* Turbo Boost, a dynamic performance technology that automatically speeds up the cores in use when other cores arent needed.
* Hyper-Threading technology allows two threads to run simultaneously on each processor core, providing eight virtual cores for increased performance.
