I have found that, despite being more recent, linux kernel 6.1 LTS works better with a core2duo than WinXP or Win7.
However, when using a DE, I cannot use KDE or GNOME on a 2GB RAM computer. It is simply not enough. On base, it uses around 1.6GB which is almost 80%. But XFCE works okayish.
On a 4GB+ RAM PC, it works flawlessly. Whether it is an older or modern CPU.
While the point of obsolescence stands, it is not enough. For example I have used a GSI android 12 on an huawei android 8 phone. It has worked better than the android 8 version.
But… 2GB of RAM is not enough to accomodate a modern android experience, on that he is right. If you want Android 12/13/14 you might want to have at the very least 4GB of RAM. Swap spaces help but are not enough.
Which is…?
