In this video, we can see that the iPhone 5S brings the exact 2x speed bump that Apple promised as it goes head-to-head with an iPhone 5 in rendering an iMovie project. Also, the iPhone 5S geekbenches high, close to the 2010 Mac Mini. Check out the geekbench test here.
I did a head to head test using the iMovie app on both devises. I loaded the exact same iMovie project and had them render head to head the same size video. the iPhone 5s rendered the video in half the time as the iPhone 5.
