Total Power different between mactop and iStat Menus

[edrozenberg]

It's probably not a bug but a difference in definition. mactop appears to consider total power to mean cpu + gpu, whereas iStat Menus appears to measure total system power (cpu + gpu + anything else).

Screenshot showing iStat Menus total power ~ 8 Watts vs. mactop showing total power .5 Watts (Mac mini M4 Pro):

This problem also exists in memory usage. Can it be customized?

I also noticed this, during a chat with a LLM on Ollama, mactop will report 30W usage vs 80W by istat menus, which seems more correct considering it's a M4 Max

mactop now in v0.2.5 uses Apple's SMC to gather full power wattage data including CPU, GPU, ANE, DRAM, GPUSRAM, and system power, the power wattage readings should now be much more accurate to something like a watt meter and other applications that use the SMC to read power.
