Does it make a big (noticeable) difference whether a Windows 10 laptop has 4GB or 8GB RAM?! Or is the feeling about the same?!
It depends on what you want to use it for. 4 GB should be enough for office work.
Even if you have Chrome and Word open at the same time you can feel the difference whether there are 4 or 8 GB of ram.
Even if it says that Win10 runs well with 4GB, the jump to the 8GB is a big difference, since it feels a bit smoother, since Windows does not have to use the swap file so much and therefore use it…
So it definitely makes sense
It depends on what you do, but if you don't want the laptop to jerk just because you're in the browser and copying something, 8GB RAM would be good even office laptops now have 8GB RAM
Under 8 gigabytes with Windows makes little sense, 8 gigabytes with an SSD - Win10 simply makes more sense, which brings a lot of speed.
If that's not enough, then 16 gigabytes of RAM.
