Did you undervolt it? Or you just got some blessed silicon. 7700 desktop was drawing 35W idle for me so I would love to get anything close to this magic.

- sva_ 2y agoIt's a mobile CPU 7040 series and you can't undervolt it. But you can limit TDP using a tool like ryzenadj. I set it to 20W on battery and the full 51W (or what it was) while connected to AC. Not sure about lottery because this is my only Ryzen PC, I think a 7840U might run a little lower though, if I'm not mistaken about the binning process. Take note this is a real idling wattage when it's not doing much at all. At the time when I tested this yesterday, I only had a terminal and browser open (Linux), and turned the screen off via dpms. https://postimg.cc/XGb3sV0F https://postimg.cc/XGb3sV0F (0.87Wh in 20m20s ~2.56W/h) With wifi off it approaches 2W
- machinekob 2y agoThis is blessed silicon for sure mine ryzen always (3000 series 7000 series) have very high power consumption in idle right now I’m mostly on M1 ultra and are around 7-10W idle compared to 45W on 3900x and 35-40 on 7700. (I have also intel server with 12700k that idle around 15W but it is undervolted a bit)
