Sometimes you want to conserve every bit of power so the SoC can boost hard when it really needs to. And you dont want the CPU/GPU running faster than they have

Sometimes you want to conserve every bit of power so the SoC can boost hard when it really needs to. And you dont want the CPU/GPU running faster than they have to, otherwise you sap TDP the rest of the chip could use. That being said, Intel IGPs arent (yet) fast enough to be throttling down in games :P
