Apple offers its Macs in a number of standard configurations; these are the systems you see when perusing the shelves of retail Apple Stores or the virtual shelves of the online Apple Store. But Apple offers upgrades for each system that can increase performance – and the price – of a Mac.
The upgrades include faster processors, faster storage devices, and more RAM, and these built-to-order (BTO) options usually offer considerably improved performance over the base standard configuration that you start with. The Macworld Lab got a few of these BTO Macs, and our new overall system performance test suite, Speedmark 6.5, shows that four of the five fastest Macs we’ve tested are BTO configurations.
More cores, faster cores
As we’ve experienced with past benchmark test results, the speed of the individual processing cores on a processor affects overall performance more that the number of processing cores. In fact, the 12-core 2.66GHz Xeon Westmere Mac Pro with 12GB of RAM and a $7629 price tag, was not the overall fastest Mac that we’ve tested. That honour goes to a $5179 BTO Mac Pro with a 6-core 3.33GHz Xeon Westmere processor and 3GB of RAM, which edged out its 12-core sibling by one point in Speedmark 6.5. The 6-core 3.33GHz Mac Pro beat the 12-core 2.66GHz Mac Pro in 12 of the 17 individual tasks that make up Speedmark 6.5.
Surprisingly, the amount of RAM didn’t matter much with our Mac Pro tests. The results from the 12-core 2.66GHz Xeon Westmere Mac Pro with 6GB of RAM (the standard configuration) were nearly identical to the results of the same Mac Pro with 12GB of RAM. Even our multitasking test wasn’t faster on the 2.66GHz 12-core Mac Pro with 12GB of RAM.
In the few Speedmark tests that make use of all 12-cores (and with Intel’s Hyper Threading technology, all 24 virtual cores), like MathematicaMark, CineBench CPU, and HandBrake, the more processors available, the better the performance. For example, the 12-core 2.66GHz Xeon Westmere Mac Pro finished the CineBench CPU test in one-fifth of the time it took the 2.66GHz Core i7 MacBook Pro to complete the test and 33 percent faster than the 6-core 3.33GHz Xeon Westmere Mac Pro.
The fourth fastest Mac we’ve tested is a BTO 27in iMac with the 2.93GHz Core i7 Quad-Core processor option, a $290 upgrade to the standard $2599, 2.8GHz Core i5 Quad-Core iMac, which came in ninth place in our Mac speed trials. The 27in 2.93GHz Quad-Core iMac even beat the 12-core Mac Pro in our Photoshop test.

Higher scores are better. Best result in bold.
The fifth fastest Mac is another custom 27in iMac with a processor upgrade: a 3.6GHz Core i5 Dual-Core iMac with a 256GB solid-state drive (SSD). And while fifth place is nothing to sneeze at, its position in the list is a little misleading, thanks to its speedy SSD. The 3.6GHz Core i5 Dual-Core iMac with SSD was the fastest Mac we tested in 7 or our 17 tests, beating the Mac Pros in file duplication, zipping, unzipping, opening Pages, encoding iTunes files, and importing images into both iPhoto and Aperture. An identical iMac system, but with a standard 1TB hard drive instead of the solid state drive finished eighth in our overall speed tests.
To give some perspective, I added the fastest Mac portable, a 15-inch 2.66GHz Core i7 MacBook Pro, to the list. It received a Speedmark 6.5 score of 151. By comparison, the standard configuration 27in 2.8GHz Core i5 Quad-Core iMac was 30 percent faster.
