Quad core and eight-core Mac Pros (Mid 2010)

These days, the consumer-oriented iMacs stand on their own against (and in some cases, surpass) the Mac Pro in day-to-day performance. Does that mean that the Mac Pro has lost its relevance in today’s work environment? Hardly.

The new Mac Pros announced in July have finally arrived at Macworld Lab. And while we ran into some hiccups during our tests, we’re able to share our first results.

Lab tested: 27-inch Core i5 iMac/3.6GHz (BTO)

Several readers wanted us to test the new 3.6GHz Core i5 iMac, a built-to-order (BTO) option for the 3.2GHz Core i3 iMacs.We ordered a custom 27-inch iMac with the 3.6GHz Core i5 dual core processor with a 256GB solid-state drive (SSD) to complement the 1TB 7200-rpm drive that comes standard. We tested the system and the results are intriguing.
