Many comparative tests have shown how much faster the iPhone 3GS is in relation to the 3G model and even compared to competing smartphones. To make the performance superiority of the new model even clearer, some tests show what its new graphics chipset is capable of.
The tap tap tap developers used an application still under development Plasma to demonstrate the frame rate achieved by each of the last two versions of the iPhone. With an ARM Cortex A8 processor at 600MHz, 256MB of RAM and a graphics processor PowerVR SGX with support for OpenGL ES 2.0 (3D rendering), the iPhone 3GS is up to four times faster than its predecessor.

According to the developers, Plasma has very intense particle animation, which requires a lot of the device's CPU. The current build The app is still using only instructions compatible with OpenGL ES 1.1, but they are considering adopting some features of OpenGL ES 2 to make the game experience even richer when running on an iPhone 3GS.
The Ziconic developers also published a video demonstrating the performance of AirCoaster 3D running on an iPhone 3GS and an iPhone 3G. Check out:
