You know PRD alone does not tell anything. You must take account of what PPT reports during that full load 70% PRD.
Depends on the CPU you have and it’s stock PPT.
Anyway, I have Aorus Pro X570 (F32 Bios) with R5 3600 that has a stock PPT of 88W.
During full load my PRD is around 89~92% and PPT report around 87W.
So the true total power consumption of CPU is:
87 / 0.89~0.92 = 94.5~97.7W
We have the same cpu. In prime95 it maxes the ppt and still on ~70% PRD. Getting upto 83c on a fuma2 in a mesh case with 140s which is plain ridiculous. Good to hear the x570 GB does better with this. Will probably buy the pro.
