For Macs, faster is always better, and you can try many things to get the most performance. But what can you rely on? We looked at some common claims.
1. More cores always means better performance.
We ran benchmarks on two 2012 Mac Pros, one with 12 processing cores running at 2.4GHz and one with a quadcore processor at 3.2GHz. With an impressive MathematicaMark score of 5.70, the 12-core’s result was twice that of the quad-core. The 12-core Mac Pro also finished the Cinebench CPU test in half the time of the quad-core Mac Pro. In contrast, however, the 12-core Mac Pro posted slower times than the quadcore system did in our iTunes-encode, Aperture, and file-compression tests.
While some pro apps can benefit from multiple processors, most consumer programs don’t…
