Apple is very tight-lipped about the specific hardware specs of the iPhone, which seems very strange to those of us coming from a console background. But people have been able to determine that the CPU is a 32-bit RISC ARM1176JZF. The good news is that it have a full floating-point unit, so we can continue writing math and physics code the way we do in most platforms.
