Two things: the cpu consumes less watts, hence dissipates less heat PER 
SECOND.

However, it takes more energy to complete a given computation because 
reportedly switching on and off the cpu is costly. This was discussed here a 
few years ago.

Therefore if you use a laptop as a gateway in a very silent environment, 
throttling may be a good idea if the fan tends to kick in (it makes 2-3C 
difference in my experience). Otherwise, forget about it.
