2. 20 watt power savings in my older test system -- P4 2.8ghz system w/ HT enabled.
I just ran a more controlled experiment on that older P4-2.8ghz system. At idle there is no difference in power consumption with "ondemand" vs. "performance". I then created a scenario where the CPU needed to run at 700mhz (The allowable range is 325 to 2800) and saw the following readings:
1. ondemand -- 89 watts
2. performance -- 95 watts.
So the savings was 6 watts. I would be interested in knowing what other's are seeing.
I don't think I have hooked my Killawatt up since 5.5, but I will say that the temperatures have dropped noticeably since using this. In my situation I am a lot more concerned with the temperature than the savings in power consumption. Sorry I'm not being any more useful, but if I get a chance I will hook up the Killawatt and post my results.
