RyzenAdj VS ExpansionCards

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 :)

I think the SD module won't be able to have the card flush, as the modules are only and SD cards are 32mm long, and you need some PCB space for the socket cage and the USB-C on the other side. The retrofit PCB outline they provide is only 26.9mm from front edge to back edge, so an SD card will stick out a little bit.

So perhaps they decided to go for the one that lets users have the card flush for use like an expansion bay as well as for data transfer to/from devices.

There are many laptops and desktops that fit the bill.

Frame.work: https://frame.work/

Dell: https://www.dell.com/support/kbdoc/en-us/000138246/linux-on-...

System76: https://system76.com/laptops

Kubuntu Focus: https://kfocus.org/land/business

I am sure there are more, this is only what I have found in less than 5 minutes of searching.

I'll buy a frame.work long before I touch system76. Their prices are too high for the general feedback I keep seeing on the quality control. I'm not spending 3k+ to be out a laptop until support responds. Especially, considering they still don't make these in house..

No they didn't, companies just mostly gave up on it.

A Framework Laptop (https://frame.work)

You could get a Framework 13 which comes with your choice of a 7840U or 7640U and a Radeon 780M iGPU. They do officially support Linux, and you don't have to pay for a Windows license, if you go the DIY option and chose to not get a Windows license.

Take a look at the Framework laptops. They're 100% modular so if stuff like that goes bad you can simply order the replacement part and do it yourself. I'm using a desktop right now but Ithink my next laptop is gonna be a framework.

a couple of days ago I tried to order a Framework laptop (13 inch AMD). I chose to create an account during the checkout process and provided my email address. After entering my shipping details, I authorized the transfer of the deposit fee via Giropay. The deposit was deducted from my bank account but when I was sent back to the frame.work website I was greeted by an error message. Unfortunately I could neither complete the checkout process nor continue my account registration.
