So the iPhone 4S benchmarks are out and it would seem they are nothing less than amazing. Unfortunately the graphics benchmark that was released by Anandtech earlier today is as synthetic as it gets; the tests used were "offscreen", in other words no image was rendered during the test. Offscreen means that the would-be-rendered image is HD but unfortunately none of the tests used an actual 720p output and monitor to verify the results.
Should you want to play games on an external monitor iPhone 4S is expected to perform better thanks to the fact that the image is mirrored as the iPhone real HDMI output does not consist of a real HD 720p image as Apple kindly informs us:
Apple Digital AV Adapter mirrors exactly what you see on iPad 2 or iPhone 4S so that everyone in the room can enjoy it on your widescreen TV[...]
Mirrored means that the screen image is actually cloned and scaled to 720p instead of having to be rendered as a second HD output. In this case most android devices suffer a larger performance drop while displaying a better quality output.
