Be careful when looking at memory pressure and how much it is using. For the same kinds of things I do, it scales well between 128GB of ram to 32 and even 16 GB of ram. If you are using a 32 GB machine and seeing it has high memory pressure or used up most of the memory, it does not necessarily mean it won’t work well on an 8 GB machine.

To know if 8GB is enough, you often need to just try it and see. So that’s why I don’t want to put myself in that situation (that I’m running out of memory and the only option is to upgrade an entire machine.)

(It is because there’s many things aggressively using more memory to make things faster or more responsive by cache things. But those can be released under high memory pressure without much apparent performance loss. That makes use the memory more opportunistically but making it hard to gauge how much really is needed.)
