Are you asking what version of the editor you should use to develop a game based on you specs? Really all versions should work. Your choice of editor should more depend on what features you need. I would recommend trying the newest 6000 or 2022.3.

Of course the specs of your dev device will limit what kind of game you can make, but the editor itself should not be a big factor.

Edit: One thing to consider is RAM. 8GB is not a lot and will probably bottleneck your dev experience. But really this will be the case regardless of editor version. If you need something more lightweight consider using a lighter engine.
