8GB RAM on M3 MacBook Pro 'Analogous to 16GB' on PCs, Claims Apple

This is a most excellent place for technology news and articles.
RAM is RAM. If you're able to manage it better, that's nice, but programs will still use whatever RAM they were designed to use. If you need to store 5 GiB of something in memory, what happens with the other 2.5 GiB, if they claim that it's 2x as "efficient?"
Definitely true, but I will say Mac has pretty decent compression on RAM. I’m assuming that’s why they feel this way. My old MBP 2013 had 8, and I used it constantly until earlier this year when I finally upgraded. It was doing pretty well all things considered, mostly because of on the fly RAM compression.
Lower end macs tend to have slower SSDs so this could be a double whammy on these machines.
I’m specifically talking about the in memory compression, not swap.
But memory compression works the same way swap works. When memory is needed LRU page is ~~written on disk~~ compressed, and where application needs to read data from compressed page it generates pagefault and OS loads(decompresses) page in memory. That's it.
It can be compressed in RAM, too.
Thanks, cap, this is what I said.
