Pretty much. Having smaller gates means three things:
1) You can fit more transistors in the same space, increasing performance
2) They have less electrical resistance which in turn means
3) They produce less heat
Typically these outcomes means you either get an equally powerful processor that runs cooler and with lower energy requirements (good for battery life), or a more powerful processor that outputs the same amount of heat and uses the same amount of energy.
