Sure. But that has taken CPU manufacturers decades to accomplish and GPUs are just making their first forrays into that territory and GPU dies contain 50x more circuitry than contemporary CPU dies. 

There is no "need to combine both low power graphics and high power graphics in one system." There *is* a need for high-performance graphics that consumes low power. The current dual-GPU solution is a hack. 

It is a hack, but it is an inevitable hack. With the price of integrated low-power consuming GPUs approaching about 0, it's very inviting to just do that hack. Also, the performance gap between mobile/integrated GPUs and discrete GPUs has not decreased really. The prediction that integrated solutions are somehow "catching up" making this gap vanish is unfounded.

- In 2008 the GMA X4500 offered about 28 gflops,  the contemporary GeForce 8800 GTS offered 624 gflops (a factor of 22x)
- In 2012 the Intel HD 3000/4000 offer about 125 gflops, the contemporary GeForce GTX680 offers 3 tflops (a factor of 24x)
