It's how your processor works with each program. It has nothing to do with SQL. So, when doing some testing, e.g. opening a chart, opening eRx, starting AC, we would take note of how high and in what cores the spikes were. We saw this on two test stations. (You can tweak SQL to run processor cores in parallel, but I certainly wouldn't recommend it on a production system based on this small sample size.
I have looked at others, and this doesn't seem to be the same. For more valid and reliable information, I would contact Guardian Sandeep.
