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.
Macworld Lab�s tests do show that the new Intel-based iMac is faster than the iMac G5 when running native applications. However, we found that those improvements are generally much less than what Apple claims is a 2x improvement in speed.’
