“Aside from the case color, the only other difference between the white and black 2GHz MacBook is the hard drive—a 60GB 5,400-rpm drive in the white model and an 80GB, 5,400-rpm one in the black. And if you were to look at their scores on our overall system performance testing tool, Speedmark, you would find data to back up that position,” James Galbraith writes for Macworld.
“However, the differences in some of the individual tests that make up Speedmark were big enough that we rushed the black the MacBook back from its offsite photo shoot to run some more tests. After testing the white 2GHz MacBook and comparing the results to the published scores of the black model, we saw small performance differences in many of the tests, with the edge going to the white model in most cases. Retesting leveled out a few tests (though I can’t explain why), but still shows the white 2GHz model performing better than the black model, most notably in our Compressor MPEG-2 Encoding test and our iMovie test applying the Aged video effect to a clip,” Galbraith writes. “With the systems shipping with identical processors, RAM and graphics, we focused our testing attention on the hard drive.”

MacDailyNews Take: Duh, almost everyone knows that black absorbs light better than white, so… uh, so that means… aw, forget it.
(Remember, all processors are not precisely equal. The actual performance measurement of your Mac’s CPU will probably vary slightly with another of the same model Mac. Other components all have slightly different tolerances (RAM, etc., so what Macworld found is a random instance. You could grab another black MacBook and find it to be slightly faster than both of their other models. In other words, the color of the case doesn’t matter, but luck does – the differences are very slight regardless.)
