Some mobile phone multimedia chips use run domains and only switch then on when needed. So there are decode/encode domains, camera ISP domains, 3D domains, mp3 domains, that are only turned on when required. One chip I have knowledge of runs at 500mA, doing all of the above....... I've always wondered why desktop graphics don't do much the same.
