I have noticed, that my computer, which I put together myself and I can give very specific details about it but I wanted to ask about the problem first.
My computer in question is a Gigabyte Aorus Z690-Pro with an Intel Core i7-12700 (no letters), which I measured at around 29 Watts idle power consumption.
So little later came the graphics card, a Sapphire Radeon RX 6600, so I could at least say, it can ray-trace and stuff.
I put the timer to one minute before my screen goes black and the computer goes idle. At the desktop and nothing running, that computer uses 62 Watts to show a picture and some icons. But that's not the issue.
My issue is that with all the Bios updates that I flashed in, the idle power consumption varied quite a bit on this one but until kernel 6.1.0-1008-oem, it was still withing the margin of what I would consider stable idle power consumption.
With the card it went up slightly but I still count 32.1 to 35 Watts a very good idle power value for a computer that brings eight more cores than I ever had before and still requiring around 20-ish Watts less idle power than my former computer, featuring a quad-core with the Skylake architekture, named Kabylake. This one used 50-ish Watts with a Radeon RX 480.
But now I have a gain of 10 to 15 Watts by just booting one of the kernel updates that folloewd 6.1.0-1008-oem.
I was hoping one of the never ones would bring me back to 33 Watts idle power consumption but every single one of them causes an uptake of 10 to 15 Watts in idle power consumption.
Please don't hit me, but I also watched my power consumption on Windoze or Reboot 11.
With the latest developer preview Windoze update, whenever that Windoze goes idle, that idle power consumption goes down to around the same 34 - 37 Watts idle power.
I have this measurement devise in my wall-plug, which shows me the power consumption of the entire computer down to single digests or 0.1 Watts.
My question now would be, what am I doing wrong or thinking wrong or messing up some vital steps that I really cannot see. My tunnel-vision in that case only sees me booting up the next kernel just like every other security update I installed over the years.
Let me know if and how specific details you would need to answer that question.
