Yeah but Mac pushes the turboboost feature pretty heavily without mentioning the inherent limitations of it. Since OSX now streams across all available cores, turboboost is essentially useless. The only time turboboost helps is when using single-threaded applications.
And I really have a hard time believing that Sandy Bridge is 2x faster than the nehalem series but hey it’s rare that I believe Apple advertising so that’s nothing new <_>
I also find it hard to believe that the ATI 6750M is 3x better than the Nvidia GT 330M but I’m just splitting hairs at this point.
