Here are some raw spec numbers that I've in my head right now, which might vary slightly in the reality: OMAP3430/N900 GPU: PowerVR SGX 530 14 MPolys/s (clocked @ 14 MPolys/s) Iphone 3GS/Itouch 3G* GPU: PowerVR SGX 535 28 MPolys/s (clocked @ 7 MPolys/s) OMAP2420/N95 GPU: PowerVR MBX lite 1 MPolys/s (clocked @ 1 MPolys/s) Iphone 3G/Itouch 2G GPU: PowerVR MBX lite 1 MPolys/s (clocked @ 1 MPolys/s) *Does not include the Itouch 3G 8GB, which has the same hardware as the Itouch 2G 8GB.
