I don't know much about iPhone hardware, but a good example of this is on the 2010 13-inch MacBook. Apple has been a leader in enabling their software to offload tasks to the GPU (see OpenCL, etc). This enabled them to stay a generation behind on their CPUs for MacBooks (keeping the Core 2 Duo alive longer than expected, giving several advantages) without falling too far behind on overall performance.
