iMac Core 2 Duo Benchmarks

MacCentral posted a first look at the new Core 2 Duo iMac along with some early benchmarks.

The new iMacs which were released on Wednesday incorporate the latest Core 2 Duo processor from Intel. The Core 2 Duo represents the continuation of the Core Duo line which first made its appearance in Apple computers in January. Intel has maintained that the new chips would provide roughly 20% improvement in performance.

MacCentral tested the new 17" 2GHz iMac and 20" 2.16GHz iMac and compared them to the previous 20" 2GHz Core Duo and the 2.66GHz Mac Pro.

The most direct comparison between the two processors comes between the 17" 2GHz Core 2 Duo iMac and the 20" 2GHz Core Duo iMac. The overall score was 10% better in the new model while the individual tests showed gains up to 20%.

As expected, the 2.66GHz Mac Pro (Woodcrest processor) outperformed the new iMacs, but the reviewers were still impressed how well the iMac fared:


With twice the number of processor cores, all running faster than the iMac, the Mac Pro had a definite advantage in this match up. But because not all applications and tasks take full advantage of the Mac multiprocessing capabilities, most results showed the Mac Pro between 20 and 30 percent faster than the 2.16GHz iMac.
