My expectation is that the savings can be much greater. Not only can you 
make do with a much less powerful CPU (leading to lower power 
consumption that you estimated at 20W), many of the other components in 
the system can also be much less powerful (or are not used as 
intensively), because there is less data to move across buses, and 
between memory and GPU.

Furthermore, I would expect that hardware that has been purpose-built 
for a particular function (in our example the GPU) is more 
power-efficient than when that function is implemented in 
general-purpose hardware (the CPU). So not all types of computing power 
are created equally.

I have no numbers, nor am I in a position to collect numbers. Until 
then, my remarks above are conjecture.

Cheers, Jan
