When a big powerful CPU is idling it isn\'t power hungry. TDP is a maximum measurement.

Why are CPUs only about 80W TDP? Can\'t they make ones with three times
as many cores that have 250W TDP like graphics cards?
Because while power dissipation is proportional to number of cores and
clock speed, for the vast majority of applications CPU clock is no
longer a bottleneck.
If you really need more general-purpose CPU power you can get a system
that supports multiple physical processors, or cluster them.
The trend is to make CPUs more power-efficient, not less!
