Linus Tech Tips ran a simple side-by-side comparison of RAM usage on Windows 11 and Linux. Opening the lttstore website on FireFox pushed Windows 11 and Linux RAM usage to 10.7 GB and 5.9 GB, respectively. So, Windows 11 consumed an additional 1.4 GB RAM and Linux used 1.2 GB of RAM over idle usage. In short, LTT’s rudimentary test shows that Windows 11 uses much more RAM both during day-to-day use and gaming. However, this doesn’t eniterly mean that Windows 11 sucks at RAM usage, as the system never got close to being RAM-limited.
