Apple Silicon M1: Black Magic Fuckery

I don't quite see that either. But I suspect that it is just macOS itself which uses less memory than Windows in general.

But the much faster SSD to RAM transfer for the M1 means that shuffling stuff in and out of RAM is much faster meaning RAM matters less.

On my almost-stock (primarily used for iOS deployment) MBP, Catalina uses 3GB RAM (active+wired) memory on boot. It's much more than my Linux laptop (~400MB). I haven't booted Win10 recently but I'd assume it'd be close to macOS.

The transfer speeds of the M1 SSDs have been benched at 2.7GB/s - about the same speed as mid-range NVMe SSDs (my ADATA SX8200 Pro and Sabrent Rocket are both faster and go for about $120/TB).

I think OS' usage isn't main matter for RAM. Browser, Electron apps, professional apps like Photoshop, IntelliJ, and VM should be.

I expected SSD is way fast, but benchmark says its SSD is about below 3000MB/s RW, not very fast but usual Gen3 x4 speed.
