Faster than quad-core G5
According to a new series of benchmarks released by Primate Labs, the top-end Mid-2007 iMac is faster than the Power Mac G5 (Late 2005) with two dual-core G5 processors at 2.5 GHz, and only slightly slower than the Xserve (Late 2006) with two dual-Core Intel Xeons at 2GHz. The Mid-2007 iMac with a dual-core Core 2 Extreme running at 2.8GHz posted a Geekbench score of 3740, significantly faster than the Power Mac G5's score of 3298, and only slightly slower than the Xserve's score of 3831. The mid-range 2007 iMac, featuring an Intel Core 2 Duo at 2.4GHz, put in a score of 3213. For comparison's sake, 1000 is the score a single-processor Power Mac G5 at 1.6GHz would receive.
