Intel N100

I've been running it for a while and it's been solid with a mesa card.
setting the irq affinity is important, other than that - pretty much no special tuning.

I did some further testing today, switched from Cinnamon to KDE, which runs much better and even better than XFCE. Here are the results of my stress testing, running for a couple of hours with 8 glxgears, two YouTube videos constantly playing, working with FreeCAD for my new machine design, and doing some compiling in the background.
Please notice that I run KDE on Wayland. When running on X11 the results are worse. The runtime of the test in the screenshot was only 4 minutes, but that was where the graphs had stabilized already. It looked the same after hours.

 

Below is the same test setup, but now with only isolcpus=3.
