Question Used RAM shown in Task Manger in column header differs from amount of RAM in column?

[Kletoss]

My Acer Aspire E 15 (Acer E5-573) has 8 GB of RAM. The Task Manager shows in the coumn header 70 % being used:

How does the result come about, since the sum of the usage shown in the column doesn't seemat all to match it at all? So more than two thirds of RAM, about almost 6 GB RAM is shown to be used but the amount of used RAM shown in the column does not reach by far this amount. Why is this?

in the same time as you can run 4 things, mine does 12 (this is a simplification, it could be more)
it means I can run a VM with 4 cores and not notice its still open (if I forget its running) as I still have 8 cores to do everything else. This has happened a few times, just put a window in front and forget

So this sounds extremely fast. And when Win updates / installs its updates and / or a Defender scan runs you won't notice it, I assume, it won't slow down the computer at all.

Things have changed. 4 cores/8 threads is bare minimum you should buy now and some have way more. I know 12 cores/24 threads exist, probably higher still.

I assume these are quite expensive.

I can't tell you what CPU to get but I would aim at 4 cores minimum - it could be different on laptops as they more worried about battery life than speed. 4 cores/8 threads still double what you have now.

But I assume the programs (and Win) generally needs more CPU perfomance nowadays and reduce that speed advance or make it no longer noticeable. I have never noticed a faster speed when buying a new Notebook. The built in batttery of the crappy Acer is not usable anymore, it runs, fully loaded, about 10 min. until the Notebook turns off.

May be I should try to make a new thread before I buy a new Notebook asking for recommendations as I absolutely do not have any idea (and buy again garbage like this Acer).

12 ciore ones are expensive but 8 is becoming the standard for a lot of games, so the price of those isn't so high. I don't know where you are but I can get an AMD 8 core CPU for about $AUD450, though its probably because there is a new family of them coming

sounds like a plan

as video showed, windows has become more efficient so you don't notice it at all on better PC. Just don't buy cheap ones.
