The new iPhone CPU is getting a lot of buzz, and for sure, it will make the iPhone 3GS more responsive than its predecessors, but I think that most users will be “shocked” to see how powerful the iPhone 3GS is for 3D graphics. Obviously, you have seen the specifications: we’re going from a fixed-pipeline graphics architecture to an Open GL 2.0 ES one. But put in simple terms, it’s like going from Half Life to Half Life 2.
None of the game demos shown at the WWDC keynote has scratched the surface of what can be done by the iPhone 3GS. We expect (hope that?) the new Doom Resurrection game to come in two versions, one for the iPhone 3GS and another for older iPhones/iPod Touch… let’s wait and see.
