Macworld Lab continues to dive into the myriad build-to-order configurations Apple offers for its latest hardware releases. Last time, we looked at the 3.2GHz Mac Pro; this time around, it’s a build-to-order MacBook Air.
Jason Snell published his review of the MacBook Air a week ago, rating the standard $1,799 system—a laptop with a 1.6GHz Intel Core 2 Duo processor, 80GB Parallel ATA hard drive, and 2GB of RAM. Though the MacBook Air is not user-upgradeable, you can choose from a few build-to-order options when ordering, such as a faster processor and faster solid-state internal hard drive. Graphics and memory options, however, are unfortunately not available.
The first of our custom MacBook Air models has arrived—a $3,098 laptop with a 1.8GHz Core 2 Duo processor and a 64GB Solid State hard drive. Our benchmark results show that it outperforms a standard-issue MacBook Air by 14 percent in our overall system performance benchmark, Speedmark 5. As always, you can find more Speedmark 5 results here.

With the processors running a little more than 12 percent faster in this custom 1.8Ghz system, some of the credit for the speed improvement must be given to the new hard drive. Indeed, the SSD-equipped model started up in just 31 seconds, much faster than the 46 seconds it took the 1.6GHz, PATA drive model. The custom system was also 14 percent faster at creating a Zip archive of a 2GB folder.
In other tests, like Compressor and Cinema4D, the 1.8GHz Air was only about 4 percent faster than the standard Air model. And in others involving HandBrake, Photoshop, iMovie and Unreal Tournament, the performance differences were even smaller.
So what do these results mean to you? Even with the speed improvement in the build-to-order MacBook Air, those looking for stellar application performance should still look elsewhere, even the low-end MacBook 2GHz model was 21 percent faster overall than the fastest MacBook Air in our Speedmark tests.
We hope to get our hands on one more configuration—a 1.8GHz MacBook Air with the standard PATA drive. That should help us isolate the performance differences between the two drive technologies. Stay tuned.
