When released the iPhone 3G S will feature a faster CPU, more RAM, and a Power-VR SGX GPU which supports OpenGL ES 2.0. According to UberGizmo this GPU is faster than the old one in two fundamental graphics metrics:
- Triangle setup: This defines how many triangles can be processed per second
- Fillrate: a measure of how many pixels can be modified per second.
Both metrics are key to increase graphics realism. But that's not it: the iPhone 3GS does not just use sheer brute force to make games look better. Thanks to the more programmable architecture of the Power-VR SGX, developers can now use techniques found on PS3 and Xbox 360 games.
The article likens the difference in graphics to the improvements made from Half Life to Half Life 2. Look at the screenshots below to get a visual idea of the enhancements.
Its been suggested that the difference in graphics between iPhone models will cause a split in the App Store.
[Half Life = iPhone 3G]
