Vista saves 75 dollars a year in energy

According to the article it says that it uses an operating system-integrated form of speedstep, reducing voltage and clocks whenever not needed. I bet that if the tests with XP were done with the CPU versions like EIST it wouldn't be as big a gap...

Pretty impressive though.

i do notice in vista my cpu voltage is lower on idle and on a load it raises. But my clocks stay the same, or else i would be pissed :P
 
XP users can use Performance on Demand (and other kinds of profiles) by installing the RightMark CPU Clock Utility. It runs my 2GHz CPU on 800MHz when I don’t need its power (most of the time).

This is the first reply on that link.. More like Speedstep...
