Power consumption idle vs. maxing out every core

Question

Are there any rules of thumb to describe about how much more energy a server will use when its cores are completely occupied, as opposed to being idle?

@ewwhite - "rule of thumb", so just in general. – Ken - Enough about Monica Sep 14 '16 at 21:26 — Ken - Enough about Monica, Sep 14 '16 at 21:26
There's no "rule of thumb". There are only datasheets. – Michael Hampton Sep 14 '16 at 21:28 — Michael Hampton, Sep 14 '16 at 21:28

High quality servers allow you to monitor this at the system hardware level.

So I suggest measuring your consumption using a representative workload. The data sheets are worst case scenarios, but are safe to use as ceiling values.
