Interesting info from the developers of TouchSports Tennis at toucharcade.com:

Quote:The most clear difference is that fact that the iPod Touch’s processor was quietly boosted to 532MHz (up from 412MHz) with the 2nd generation model introduced in September. Meanwhile, the iPhone 3G, Original iPhone and 1st Generation iPod Touch continue to run at the original 412MHz.

It seems that there are additional factors, however, as there are performance differences even found between the models that run at the same speed. The models rank in the following order (fastest to slowest) for 3D rendering, with the 2nd Generation iPod Touch being the fastest “by far”.

#1. iPod Touch 2nd Generation
#2. iPhone 3G
#3. iPhone (original)
#4. iPod Touch 1st Generation
