intel-undervolt VS RyzenAdj

10th gen is locked by "Overclocking lock" And "Cfg lock" in bios, you can disable it thru ifr and use any software to undervolt your cpu (throttlestop on windows, linux has its own software (this, probably)). This is a lot safer than just putting voltages in bios as you can guess.

On Windows machines and laptops with Intel cpus, I almost always use Throttlestop to tweak power consumption and thus temperatures. I'd like to do so on this machine as well. I've found this: https://github.com/kitsunyan/intel-undervolt

intel-undervolt - though I may not be using this optimally. CPU: -75, GPU: -50, CPU-Cache: -75

You can use intel-undervolt to modify the voltage, TDP.

I will try your suggestion about limiting power package. I've been using this 3rd party intel-undervolt software, which I'm not sure if it supports granular changes to wattage, but it seems like there is some energy/performance settings there.

I personally use intel-undervolt and auto-cpufreq.

You can also undervolt though software on Linux based OS's. For intel there's these: https://github.com/georgewhewell/undervolt (this one looks more popular) https://github.com/kitsunyan/intel-undervolt (this is the one I use, no particular reason)

intel-undervolt also works fine for Intel laptops (I've used this successfully with my 11th gen H laptop).

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
