Windows 10 introduced memory compression. Here's a discussion from 2015 [0]. And one on Linux by IBM from 2013 [1]. But the history goes way back [2]. I don't know why that '8GiB is great!' -- no, no it isn't. Your memory usage just spills over to swap faster. It isn't more efficient (not with those 16KiB pages).

Yes, I'm aware that Windows has memory compression, so let's think about why it's less successful and Windows systems need more memory than Macs. The Apple version has a very high-performance hardware implementation versus Microsoft's software implementation (not a slam on Microsoft, they just have to support more hardware). The Apple designers can assume a higher performance baseline memory subsystem because, again, they're working with hardware designers at the same company who are equally committed to making the product succeed. The core Mac frameworks are optimized to reduce VM pressure and more Mac apps use the system frameworks, which means that you're paying the overhead tax less. Many Mac users use Safari instead of Chrome so they're saving multiple GB for an app which most people have open constantly as well as all of the apps which embed a WebKit view. Again, this is not magic, it's aligned incentives. Microsoft doesn't control Intel, AMD, and Qualcomm's product design, they can't force Google to make Chrome better, and they can't force every PC vendor not to skimp on hardware. They can and do work with those companies but it takes longer and in some cases the cost incentives are wrong – e.g. a PC vendor knows 99% of their buyers will blame Windows if they use slower RAM to save a few bucks or get paid to preload of McAfee which keeps the memory subsystem busy constantly so they take the deal which adds to their bottom line now. | |||||||||||||||||||||||||||||||||||||||||

He didn’t say 8 gigs is great but that you can get by with about 8 gigs less than equivalent on Windows. | |||||||||||||||||||||||||||||||||||||||||
