throttled VS RyzenAdj

Yes i know it sounds wild but I need to be able to focus on my programming tasks. I run linux on my system and with throttled installed, it gets noisy and i'm tired of it. I'm not a gamer but I use win10 and win11 VMs and compile source code and just every day tasks spin up this fan. Before I installed throttled ( https://github.com/erpalma/throttled ) it was out of control. I haven HP 840 G5 that hardly even spins up. I got this because i had the same one for work and noticed it never bothered me. I have compared some compile times on the i5 and the i7 and even my desktop, they are all about the same so I dont see why I should care about having an i7. Im willing to buy a new mobo with the i5 8250 and just use that. i bought the dual heatsink fan and waiting for that to arrive so i'll install that first. But can anyone else share their experience with an i5 vs i7 and fan noise?

I have a T480 with an i7-8650U and I am a little confused undervolting using throttled

It's the reverse. For some reason, the embedded controller (EC) on the T480 (and other later Intel Thinkpads) is aggressive with regards to throttling the CPU clock speed even when the temperature isn't that high. To solve this, someone made a program called throttled https://github.com/erpalma/throttled to fix the issue.

Planning to install Arch (EndeavourOS) on it. In the arch wiki and these forums, thermal throttling is mentioned per this post - https://www.reddit.com/r/thinkpad/comments/870u0a/t480s_linux_throttling_bug/. However this is 5yr old. Is throttling still an issue? And do you need to install throttled (https://github.com/erpalma/throttled) ?

Thermal throttling can be tweaked through throttled.

The machine throttles, under (only) Linux, when too law a CPU temperature is reached. Lenovo promised for months to fix this and then announced that it would not, after all, fix it. But the community came to the rescue.

The only thing with the X1C series though is that the thermals straight-up sucks; the laptop out of the box gets really hot really quick and throttles immediately. The first thing I did when I got it was undervolting the CPU with throttled, which helped a lot and increased my battery life significantly too. The fan basically only comes on under pretty heavy load now; before it sounded like it was about to achieve liftoff at about 20% cpu load.

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
