iTunes is a free application for your Mac or PC. It organizes and plays your digital music and video on your computer. It keeps all your content in sync. And it’s a store on your computer, iPod touch, iPhone, iPad, and Apple TV that has everything you need to be entertained. Anywhere. Anytime.
In this benchmark we take a 640MB .WAV file and convert it to a 160kbp/s .mp3.
iTunes is not a heavily threaded app as you can see in the screen shot above. At most it uses two CPU cores for converting to mp3, so clock speed and an efficient architecture reigns supreme. Again our Kingston HyperX Genesis 2133MHz memory kit shows that performance does increase as bandwidth improves. It drops 2 seconds off of the conversion time when overclocked to 4.9GHz compared to the 1600MHz speeds.
