I think the problem is that by definition, the two processor architectures are not comparable (on Speed alone). To say that a 1.4 ghz G5 is the same speed that a 1.4 ghz P4 is at best naive. I'm not a mac evangelist, but Macs have been plenty fast for a very long time with slower actual clockspeeds than wintel. We'll just have to wait and see till someone takes the time to optimize them.
