The power consumption interface was added to Sandy Bridge. So the older generation of CPUs won't display this value. There is no way to accurately measure power consumption from data provided by the CPU.Does that Power field show up for the i7 875K? I'm not seeing it.
What do you mean by 'static power consumption'? The power consumption is measured in energy units (joules) and converted to Watts via a formula.It does but it reads some internal sensor on the chip that reports the power consumption and near as I can figure, after playing around with it, it only reports dynamic power consumption and is totally blind to static power consumption (which in some cases can represent 50% of the total power consumption).
I'm not sure what good the power consumption estimate is since it seems to only capture and report half of the critical stuff.
Core Temp displays the power the processor was consuming between the last and current reading. Meaning that if you see 100W displayed it means the CPU was consuming an average of 100W/hour in that period of time. Core Temp's default polling interval is 1 second.
And just to clarify, the power consumption displayed is for the whole 'package' and not just the cores.
