Power Mac Tests Spark Debate
Some power users are grumbling about what they say are shortcomings in the performance of the Motorola chips in Apple's latest pro towers. Apple says they aren't looking at the whole picture.Apple Computer Inc.s latest professional desktops have sparked a heated debate in the Mac community. At the center of the controversy: Are the dual Motorola PowerPC G4 processors within each Power Mac able to draw on the architectural enhancements being touted by Apple? Among a raft of other architectural enhancements, the new Power Macs, announced last week in dual 867MHz, 1GHz and 1.25GHz configurations, are the first to include DDR memory. Apples Web site says that this change boosts throughput between memory and the system controller to 2.7GB/sec, increasing "total system performance." Bare Feats, a Web site that speed-tests Apple hardware, pitted the new dual 1GHz model against the companys previous top-of-the-line offering, an SDRAM-based dual-1GHz system that Apple unveiled in January.
Rob Art Morgan, proprietor of Bare Feats, concluded that the new DDR Power Mac has no apparent performance advantage. Morgan told eWEEK that the tests he ran take advantage of the CPU, memory and other system components in varying degrees, depicting typical consumer and professional use.
