Actually no, it’s not “faster”, as both are based off the cortexA8 CPU. By definition, the Snapdragon has a higher frequency, so it goes through cycles faster. What you might be trying to say is that it renders polygons faster. Actually, it doesn’t do that in raw settings either, but since the PowerVR SGX hardware accelerator in OMAP3 is better supported than the modified version in Snapdragon, it often does produce better polygon rendering results.

Guess how many polygons are in Starcraft? Very few. It’s all sprites, which you can argue are squares, but in general, a game like this will run better on snapdragon. A polygonal game that depends more on hardware rendering could definitely edge out snapdragon though on the OMAP3 or S5PC100(iPhone3GS)
