Black and white differences
When we first posted our review of Apple’s new MacBooks, we didn’t include a mouse rating or benchmark results for the white 2.0GHz model. The reason for this omission? While we were able to get our hands on the 1.83GHz and black 2GHz MacBooks fairly quickly, it took a little longer to track down that third model.
Well, the white 2GHz configuration arrived finally, so we put the laptop through our battery of tests. You might think, “Why did they bother?” After all, 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.
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.
With the systems shipping with identical processors, RAM and graphics, we focused our testing attention on the hard drive. Thankfully, switching hard drives between the MacBooks is fairly painless, because we did a lot of it and found that the results in question followed the drive to whatever system it was installed in. We bought and installed a 100GB, 7,200RPM Seagate drive in the black MacBook and saw its performance benefit immediately, reducing the gap between white and black on many of our tests, like Compressor, iMovie and iTunes, while whipping the white in the more drive-intensive tasks like zipping, unzipping, and duplicating files.
The weirdest results came from our iPhoto import test, which appears to be very hard drive sensitive. Surprisingly, the winner wasn’t the Seagate 7200RPM drive, but the Fujitsu 5,400-rpm drives found in the black MacBook and 17-inch MacBook Pro. The white MacBook had a Seagate 5,400-rpm drive, which edged out the Fujitsu in zipping and unzipping large folders, but lagged far behind in the iPhoto test. The top-level specs of these drives don’t offer any explanation—both have 8MB caches and both run at 5,400-rpm. We installed, wiped, reinstalled, and moved the drives around trying to figure this one out, but the results always followed the drives.
Other results, like those from Photoshop, 3-D games, 3-D rendering tasks, Web browser tests, Microsoft Word scrolls, and so forth, were very similar, which explains the very similar composite Speedmark scores.
