@HackintoshNoobie,hm, interesting. So here is my Power Gadget for the duration of me playing the H264 clip (which i exported out of FCPX) playing. The red underline is where i played it then paused it. Do you mean that the CPU Core frequency should be pegged or the iGPU frequency? Why is this the case?
Did you mean to attach an image ?
IGPU frequency should be pegged when using a desktop SMBIOS (system definition) and configured as headless , MacOS does this as there is no need to throttle the IGPU as it's only used as a kind of GPU co-processor to the main dGPU. As desktops such as iMac run from mains power there is really no advantage to throttling the IGPU as it does not genearte any more heat and uses very little extra watts of power.
MacOS only throttles the IGPU when using a SMBIOS such as MacBook Pro or MacBook Air.
