Intel is showing off a mobile Haswell prototype (reference board currently in a desktop form factor) at CES and decided to test its integrated GPU (GT3 in this case). They claim its performance is on par with an NVIDIA GT 650M an ran a comparison demo to prove it. Both systems are running Dirt 3 at 1080p with those graphics settings: The Haswell computer is on the left, GT 650M computer on the right. Here's the video in which you can see both in action: http://www.youtube.com/watch?v=VPrAKm7WtRk Both look pretty fluid. Thought this may be of interest for anyone waiting for Haswell to buy a 13" rMBP.
