Universal-x86-Tuning-Utility VS RyzenAdj

Makes sens though. Overclocking APUs in laptops is much more trickier and riskier than desktop CPUs, especially that the optimal settings have already been tuned by the OEM in firmware based on known thermal and VRM power design limitations.

If you really do want to tinker with your laptop APU try this:

I'm talking about this tool It works wonders in Windows for my gaming laptop.

Theoretically, you should be able to. Try disabling "Core Isolation" in Windows Defender settings and then messing around with this tool: https://github.com/JamesCJ60/Universal-x86-Tuning-Utility

If you want a game booster, you should just probably use something like UXTU. I've been using it and it usually works really well with games*. Just use the presets.

A little odd its not supported, https://github.com/JamesCJ60/Universal-x86-Tuning-Utility?

Oh and here's the link for AATU's GitHub. You can see it's called UXTU now. https://github.com/JamesCJ60/Universal-x86-Tuning-Utility/releases

Releases · JamesCJ60/Universal-x86-Tuning-Utility (I like this one) There's a place to apply setting's adaptively and it works well.

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 :)
