Miminal specs for armbian with desktop GUI

[ThreeNamesGrace]

Hello, I am planning to desgin a Computer-on-Board, but would like to know what are the minimal specs needed for it to run a graphical user interface with a desktop. Doing a simple Google Search gives me two answers: "512 MB RAM memory, at least 8 GB of storage (on a quality SD card or eMMC), a 4-core processor, and wired networking. For a more advanced Armbian build framework, you'll require a system with at least 8GB of RAM and 50GB of disk space, although specific requirements vary depending on the hardware."

 

My main issue with this is that it doesn't explain directly if 512 MB of RAM and a 4-core processor (and what frequency?) are enough for the most lightweight GUI desktop.

It seems like there is a mix-up between specs for the framework and for the OS. A lightweight desktop can run on 512MB, yes but probably not much fun, depending on applications. Won't recommend running a web browser. 

I'd probably get some existing cheap sbcs with similar specs and play with them to elaborate if the performance is sufficient.
