> Is power consumption directly related to clock speed in some way?
Pretty much always. On the digital side of things transistors use most
power whilst switching (as opposed to being in steady state on or off),
so the more switching they do per second the higher the average power
consumption. On the analogue side the details probably vary depending
on exactly which DAC architecture you're using, but in general I can't
imagine power going down at higher clock speeds. Higher clock speeds
mean faster rate of change of voltage, which usually means higher
currents are involved, so more power gets dissipated in various components.
