This entry-level Mac Pro is fast. Very fast. At 2.8GHz, its Intel Xeon processor might look slow compared to the 3GHz-plus chips offered by most of the current iMac range, but its clock speed belies its true performance. Like the Core-i series, Hyper-Threading allows two threads to run on each of its cores, giving this model eight virtual cores. And like the Core i5 and i7 chips, Turbo Boost shuts down unused cores and boosts those that are active to a maximum of 3.06GHz. In our Cinebench rendering test, its single-processor score was just under 3 percent down from the 3.2GHz mid-2010 iMacs, but when all processors were brought into play, it outperformed the all-in-one by an incredible 67.5 percent. The Mac Pro’s new ATI Radeon HD 5770 is up to five times faster than the standard graphics cards offered by the previous Mac Pro generation and even outperforms its speediest configure-to-order option. It ran our Doom 3 test at almost 180 frames a second, and our five-minute test movie encoded to iPod format in just 129 seconds. What’s that boil down to? Although it’s designed for professionals, there’s clearly an advantage in having a Mac Pro as a home machine.
