This highlights one of my pet peeves with the integrated versus discrete debate. The reason why typical GPUS have high power consumption is because they are generally designed for the desktop market where they can. But you can have low-power discrete GPUs also. For that matter, there is no reason why you cannot have a low-power discrete GPU, and a high-power discrete GPU. And again, it's a whole lot easier to dissipate heat being produced in multiple places than all in one hotspot.
