Apple's recently announced iPhone 3GS will sport a new video camera and a digital compass, but it's the increased processing horsepower that is stirring up the mobile gaming space. According to AnandTech, the iPhone 3GS' graphics chip can produce 7 million triangles and render 250 million pixels per second running in its lowest configuration, representing "7x the geometry throughput of the iPhone 3G and 2.5x the fill rate."

As I mentioned earlier, the Palm Pre uses a similar combination of hardware to what I expect from the iPhone 3GS. TI's OMAP 3430 combines a Cortex A8 CPU core with a PowerVR SGX 530 GPU. The difference is that while the Pre uses its excess horsepower to enable user-level application multitasking, Apple won't be. The Pre is most definitely faster than the iPhone, but it still has some rough edges. Combine the power of the Pre with the highly optimized software stack of the iPhone and you've got the recipe of an extremely fast iPhone. While I've yet to play with one, on paper, the 3GS should be every bit as fast as the videos make it seem.

The iPhone 3GS' performance upgrades should make the phone feel a lot faster, but the real improvement will be what it enables application and game developers to do. Apple recently hired two former AMD/ATI CTOs, presumably to work on some very graphics-centric projects. The iPhone 3GS may be a mild upgrade from a consumer perspective, but what it's going to enable is far from it; watch out Nintendo. Remember the performance gains we saw in the early days of 3D graphics on the PC? We're about to go through all of that once more in the mobile space. Awesome.

Looking toward the future, there's always more around the corner. There's the Cortex A9 which brings multiple cores to the table, and the PowerVR SGX engine can be scaled up simply by adding more USSE pipes to the architecture. Newer manufacturing processes will enable bringing these technologies to life without any decrease in battery power.

It's curious to me how central ARM and Imagination Technologies are to these smartphones. On the PC side it's all about Intel, AMD and NVIDIA but when we're talking Pres and iPhones it's all ARM and PowerVR. Intel wants to bring Atom down to ARM power consumption levels and NVIDIA desperately searches for treasure in the mobile market, but those two are the underdogs in this race. For the foreseeable future at least.
