Today I've upgrade my iPad 2 to iOS beta 7 and I was thinking that a more "realistic" comparison for the HTML5 Mobile Speed reading would with the new iPhone compared to a new Windows Phone Mango device (new year new hardware). On my Omnia 7 with 7712 build and video drivers not optimized for Mango I get around 30fps, the same that I was getting on my iPhone 4 with iOs5 beta. I remember that on a tweet I read that, on some devices, Windows Phone 7.5 Mango was doing 60 fps. On the other hand the new iPhone will probable have the A5 processor just like the iPad2 so I've run the same test on my device and the results are not bad at all. The iPad2 with iOs5 beta 7 is doing a stable 60fps. This is the frame rate we can expect from the new iPhone.So Apple and Microsoft are, for now, at the same level and let's hope that the OEM's will optimize their video drivers for Mango in order to get 60 fps, if not it could be a boomerang for Microsoft (the new iPhone, doing 60fps, would smash WP7 Mango that is doing 30-40fps). Hope it won't happen.
Here is the test on the iPad2
