First Lab Tests: iMac with Intel Core Duo processor

Since the first rumors of an Apple switch to Intel, everyone has been wondering about the potential speed of Intel-based Macs. Last week’s announcement of the first shipping Intel-based Macs brought with it the promise of a major speed boost: Apple’s Web pages suggest that the new iMac, powered by the Intel Core Duo processor, is twice as fast as its G5 predecessor.

Our tests found the new 2.0GHz Core Duo iMac takes rougly 10 to 25 percent less time than the G5 iMac to perform the same native application tasks, albeit with some notable exceptions. (If you'd prefer, that makes the Core Duo iMac 1.1 to 1.3 times as fast.) And we also found that applications that aren’t yet Intel-native—which must run using Apple’s Rosetta code-translation technology—tend to run half as fast as the same applications running natively on the iMac G5.
So, it's no surprise that Apple's claims are bogus. After all, the company has been touting similar performance benefits over the years for various products, all of which have proven to be false. But I find it somewhat sad that the Intel iMac doesn't perform better, and not just because I bought one.
