RyzenAdj VS ryzen-controller

Out of curiousity how the 7840HS performs at different TDP, I did some benchmarks using Geekbench 6.2.0. To change the TDP, I've used the software RyzenAdj like so:

TLDR: Ryzen Adj.

A few years ago I did a bunch of poking w/ a 4800H, you can see the actual mechanics of using RyzenAdj. There are also Geekbench 5 benchmarks linked from the doc at different power limits which you can compare to 4800U devices on Geekbench's site: https://github.com/lhl/linuxlaptops/wiki/2020-MECHREVO-Code-...

Note, each laptop manufacturer may choose their different power limits (and like Intel, AMD's curves are largely driven by temperature, so dependent on cooling solution and other settings).

This is a good summary of some of how Ryzen Mobile's power limiting works (actually, read that whole wiki if you're interested in the topic): https://github.com/FlyGoat/RyzenAdj/wiki/Renoir-Tuning-Guide

I'd also look up "AMD PMF" (their equivalent of DPTF) which only recently made it's way to the Linux kernel (but of course, that will include loads of details anyone can look through): https://www.phoronix.com/news/AMD-PMF-CnQF-Linux-6.1

That app just uses (under the hood) this one https://github.com/FlyGoat/RyzenAdj - g-helper not using that , as it requires admin rights to run :)

Also, you can use the Ryzen Controller software to completely limit the temperature of the CPU. It lowers the performance of the CPU but also lowers the power consumption. Because there is dedicated graphics, for just general tasks like web browsing you can even limit it to 50 degrees and it will not go above that no matter what you do. It makes the PC slower for more intensive tasks so of course you'd want to raise the temperature limit setting when you want to do heavier work. The nice thing is that this method does not create additional noise, it simply lowers the performance of the CPU.

here you go my friend

/u/Number-1Dad circling back, and I'll be damned. After a bit of finnagling, Ryzen Controller is woring rather interestingly. The TDP limiter stops the whole thing short of takeoff.

Ryzen controller got your back. Newest version might not work with your CPU, old one will. The trick here is to limit your iGPU clocks to the lowest possible for everyday usage and let your system decide in gaming. You can also set throttle temp for processor to avoid throttling.

I was looking into using envycontrol to disable the dGPU in linux, and maybe ryzen controller or cpu-power to limit cpu power usage.
