package power value calculation about asitop HOT 3 OPEN

@nsklaus The reason the values differ is due to their different metric sources:

• Asitop uses powermetrics which gets its values from the IOReport.
• Stats, last I checked, accesses keys from the SMC.

It is a large difference in power, though! Even considering the efficiency of Apple Silicon, a <1 watt value is a little low for the entire package, especially when at those specific usages... So I would say, in this case, Stats may be the more accurate one. Though, the difference could be from lack of synchronization between the two app's metric sampling times.

@BitesPotatoBacks, thanks for telling. i thought too that <1w numbers were a little too good to be true.
then there may be an error in how asitop calculate the package power value ?
if asitop just grabs value given to it by powermetrics, then powermetrics is wrong?
somewhere something went bad.
my goal is trying to assess how much heat is produced and how much power does this laptop consume.

@nsklaus The values powermtrics pulls are actually counters; they are retrieved between two samples and then calculated. It is definitely possible that these counters are less reliable than the SMC (or completely incorrect in some cases), which makes sense, as the SMC gives raw values from the sensors. So yeah, definitely a issue on powermetric's part...
