I bought a second-hand office-grade PC recently, about a year ago. It was about $10 to $15, had no disks (obviously) and just 2 GB of DDR3 RAM. Also, an integrated GPU with some low-grade Intel CPU (Pentium, if I’m not wrong). Even the generation isn’t current, it’s about a decade old, a bit more.

I put a spare 120 GB SSD, a cheap no-name brand that was just lying around for some testing purposes. Found the similar off-the-shelf DDR3 2 GB RAM stick. I thought the RAM was faulty, turned out it’s in a working condition, so I put it there.

I need the computer for basic so-called office work (a browser, some messengers, email client and a couple of other utilities). I thought I’d buy at least two 4GB RAM sticks after I test it, so you know, 8 GB is just the bare imaginable minimum! I have my 16 GBs everywhere since, idk, maybe 2012 or something.

And you know what?! It works very well with 4 GB of RAM and default Fedora (it’s 40 now, but I started with 38, iirc). It has the default Gnome (also, 46 now, started with 44, iirc). And it works very well!

It doesn’t allow me to open a gazillion of browser tabs, but my workflow is designed to avoid it, so I have like 5 to 10 open simultaneously.

Before throwing Fedora at the PC, I thought I would just install a minimal Arch Linux with swaywm and be good. But I decided I don’t want to bother, and I’ll just buy 8 GB later on, and be done with it.

And here I am, having full-blown Gnome and just 4 GB of RAM. I don’t restrict myself too much, the only time I notice it’s not my main PC is when I want to do some heavy web-browsing (e.g. shopping on some different heavy websites with many tabs opened). Then it slows down significantly, till I close the unnecessary tabs or apps. All the software is updated and current, so it’s not like it’s some ancient PC from 00’s.

Also, I have my iPad Pro 12,9 1st Gen with just 4 GB of RAM too, and I never feel it’s slow for me.

I understand that some tasks would require a lot of RAM, and it’s not for everyone. Having a lot of RAM everywhere, I’m quite used to not thinking of it at all for a significant part of my career (for over a decade now), so I may have something opened for weeks that I don’t have any need for.

So, it’s 2024, and I’m surprised to say that 4 GB of RAM is plenty when you’re focused on some tasks and don’t multitask heavily. Which never productive for me at least. I even noticed that I enjoy my low-memory PC even more, as it reminds me with its slowdowns that I’m entering the multitasking state.

I use swaywm on my Arch Linux laptop, and most of the time it’s less than 3–4 Gb (I have 16 Gb).
