17-inch MacBook Pro Benchmarks

Following the top-to-bottom refresh of Apple's laptop line announced in October, people paid plenty of attention to the new unibody MacBook and MacBook Pro models. Little to no attention was given to either the top or the bottom of the line.

Now that we've reviewed the new MacBook and MacBook Pro models, we can turn our attention to those two extremes. We rated the low-end of Apple's laptop offerings--the 2.1GHz MacBook in the white plastic enclosure--when that system first debuted in March. As for the top of the line, we've now gotten our hands on Apple's 17-inch MacBook Pro--the largest laptop in the company's product line.

Apple made only subtle changes to this MacBook Pro. The 17-inch offering features a higher-resolution 1,920-by-1,200 screen as the standard display, 4GB of RAM, and a higher capacity hard drive. The 17-inch model's 2.5GHz processor is actually a slower clock speed than the 2.53GHz Core 2 Duo chip that powers one of the 15-inch MacBook Pros.

Macworld Lab's tests indicate that despite the lack of any great leap forward in the 17-inch model's under-the-hood specs, this laptop is still a very good performer.

Unlike most of the systems we test which are standard configurations, the 17-inch MacBook Pro we got our hands on is a loaner from Apple that came equipped with an optional 7,200-rpm hard drive. Typically, the 320GB Serial ATA drive in the 17-inch model runs at 5,400 rpm. Upgrading to 7,200 rpm adds US$50 to the cost of the $2,799 MacBook Pro, bringing the total cost of our test system to $2,849.

The faster spinning drive in our 17-inch MacBook Pro helped our test system post a Speedmark score of 249, 18 points higher than the new 15-inch 2.53GHz MacBook Pro ($2,499) and 10 points lower than a build-to-order 15-inch MacBook Pro with the optional 2.8GHz Core 2 Duo processor ($2,799).

The new 17-inch model's Speedmark score was also higher than that of the 17-inch model released in February by an impressive 13 percent. Even after leveling the playing field by upgrading the older system to use 4GB RAM, the new model showed performance gains in hard drive-related tasks such as zipping and unzipping a 2GB folder and in our Photoshop test suite.

The new 17-inch MacBook Pro posted an identical Speedmark score to the 2.66GHz iMac, with very similar results for most tests, including Photoshop, iMovie, and Compressor. The only big difference was in our 2GB folder unzip test, in which the 17-inch MacBook Pro finished 19 percent faster.

The 17-inch may be a high-end model, but its portable size creates limitations that causes it to struggle to keep up with the Mac Pro's 8 processing cores in many professional applications. The Mac Pro finished our Cinema 4D scene render in less than a third of the time it took the 17-inch MacBook Pro, for example. Of course, even with handles, the Mac Pro is not a practical portable.
