Apple Mac Pro Server: MC915B/AChoose your cores: 4; 6; 8; or 12.
The new Mac Pro offers two advanced processor options from Intel. The Quad-Core Intel Xeon ā€œNehalemā€ processor is available in a single-processor; quad-core configuration at speeds up to 3.2GHz. For even greater speed and power; choose the ā€œWestmereā€ series; Intelā€TMs next-generation processor based on its latest 32-nm process technology. ā€Westmereā€ is available in both quad-core and 6-core versions; and the Mac Pro comes with either one or two processors. Which means that you can have a 6-core Mac Pro at 3.33GHz; an 8-core system at 2.4GHz; or; to max out your performance; a 12-core system at up to 2.93GHz.The single-die advantage.
Many multicore processors are composed of two separate dies; which means some cached data has to travel outside the processor to get from core to core. Thatā€TMs an inefficient way to access information. Enter the Quad-Core and 6-Core Intel Xeon processors. Their single-die; 64-bit architecture makes 8MB or 12MB of fully shared L3 cache readily available to each of the 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 thatā€TMs up to 1.5x faster than the previous generation.Fast memory. And lots of it.
System memory is often connected to a processor through a separate I/O controller. But Intel Xeon ā€œNehalemā€ and ā€œWestmereā€ processors feature an integrated memory controller. 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.
The integrated memory controller; along with fast DDR3 ECC SDRAM at either 1066MHz or 1333MHz; gives Mac Pro an increase in memory bandwidth over previous generations. More bandwidth al
