The 64-bit Nehalem architecture is much faster and supports Hyper-Threading. This allows two threads to run simultaneously on each core, so MacOS X recognizes sixteen virtual cores on this model. It also allows Turbo Boost, which boosts the processor speed based on workload. This means that if an application is only using one of the eight cores it will automatically increase the speed of the core in use and turn off the unused cores). In fact, praised by many as Apple’s most customizable computer, the Mac Pro rivals or even surpasses in many cases surpasses the performance of the similar iMac models. The elegant aluminum case design maintains Apple’s trademark stylish professionalism.
