For example, tThe 2.66GHz quad-core Mac Pro posted faster speeds in Photoshop, Compressor, iMovie, iTunes, and 3-D game benchmarks than the previous standard eight-core Mac Pro.

All the innovations described above translated to better performance.

This let a 2.93GHz Xeon, for example, run at speeds as high as 3.33GHz (specifications based on Apple’s guidelines). Turbo Boost helps speed up the majority of applications that haven’t been written to take full advantage of multicore processors by allowing the system to spin down idle processing cores while increasing the speed of the processors in use.

Also new to the Nehalem processors was a technology conceived and developed by Intel and known as Turbo Boost. This structure helped use the available processing power more efficiently. According to Apple, a technology called Hyper-Threading created two virtual cores per each physical core, allowing each physical core to run two processes at once.Initial Price: $2499 – $2999 (depending on specifications).
