Inspired by this thread i ran my own tests.
I'm now a registered Apple Developer (was needed to get the necessary tools - check the other thread linked above) and ran various tests.
This was all done on 10.8.2, using a Core i7 with 3.0 Ghz. Everything closed but Textwrangler, Quartz Debug and Safari, Webkit, Mail etc for the respective test.
Take note that to get an average i scrolled up and down a lot. The initial scroll down of a website or PDF was lower than the scores you see here.
Most surprising for me was to see that the "Best for Retina, 1280x800" wasn't giving me the best results but the 2nd highest scaled resolution, 1440x900. Logic dictates that this shouldn't be the case so i repeated the first tests to make sure I'm not running into some strange things.
Conclusion is obvious as in the other thread - there is lots of room for improvement to the render engines as the Webkit development shows a 50% or more improvement. I truly believe that the HD4000 is fast enough to drive that many pixels and with software updates to the necessary applications and libraries all the scrolling threads will become a thing of the past.
p.s. LOL@Microsofts render Engine in Office/Excel.
