Ok... as the title says... this is probably the dumbest question on earth... but what do benchmarks really tell us? I know that on xbench they state that it "is useful for comparing the relative speeds of two different Macintoshes", but what do the numbers actually mean? I know that "real world" performance means more than just benchmarking numbers, but I'd like to understand what the actual meaning of these numbers means. The MacWorld article on the new PowerMacs states that the new machines are not any fast than the previous models even though the previous speedmark scores differed. The Barefeats iMac vs. dual-core PowerMac gives examples how the 2.1 ghz iMac actually beats a dual-core 2 ghz Powermac in certain tests. I just wanted to know how benchmarks actually help the consumer other than telling them that the old model had a number of "1000" and the new model has a number of "1050". I know it's dumb, but I just would like to hear everyone's thoughts on this. Thanks.
