Mobile GPUs, like mobile CPUs are permanently soldered to the main board.
This isn't always the case. The base 21.5" iMac has a CPU that is permanently soldered to the motherboard, but the 27" iMac does not. I'm pretty sure, however, that the GPU is soldered on permanently in both models. I could be wrong.
