You can think of power consumption as a resource -- if you reduce power consumption of existing features you can put more new features. The actual size isn't really that important (other than the cost of silicon wafer). To significantly reduce power consumption you need improved process and this is where smaller nodes are so important, because they are currently the only really viable way to significantly reduce power consumption.
