It was sad seeing AMDGPU limit undervolting semi-recently. A couple complaints or bits of damage ruined a practice that a lot of people were using just fine to save significsnt wattage, https://www.phoronix.com/news/AMDGPU-Lower-Power-Limit

Super frustrating. From the mailing thread:

  However, this is not good as it remove under-powering range too far. I was getting only about 7% less performance but 90W(!) less consumption when set to my 115W before. Also I wonder if we as a OS of options and freedom have to stick to such very high reference for min values without ability to override them through some sys ctrls. Commit was done by amd guy and I wonder if because of maybe this post that I made few months ago(business strategy?)
I have certainly crossed a threshold where hardware seems good enough. I do not need the 99th percentile performance if it comes with a non-linear increase in power consumption.

But this is how AMD, Intel and Nvidia have been pushing performance improvements to consumers every generation. To quote Darth Sidious: "UNLIMITED POWER!"
