Because computing architecture is based around powers of 2, and having memory that follows that pattern is more efficient.

But what about Android phones? I see there are not many issues on that side with that amount.

Try having Chrome, Spotify, and Discord open all at once. You're going to start pushing that 8 GB further than you'd imagine.

Yeah, I see a pattern here, all of that is Chrome lol.

My former work PC (which I mentioned before) that had 4 GBs of RAM required to be running always Windows 11 with Chrome, Microsoft Dynamics, Outlook, Microsoft Word, Excel, Sumatra PDF and some other few apps, so yeah I agree it was miserable, but I remember I could have Spotify as well, and AFAIK there are still Chromebooks shipped with 4 GBs of RAM? Granted they are more alike to a phone than a PC.

(looking at you Chrome devs, and anyone who uses Electron).

Definitely, my girlfriend uses a lot Notion on my Mac, and while the RAM isn't an issue there we can see the fans spinning non stop when it is in use lol, I told her to open it on a Firefox tab and it was much much quieter.
