The RAM or SSD are specifically not faster because of its “integrated nature”. The RAM is faster because Apple engineered an actually wide bus + multiple channels for memory access. The fatter Macs have the equivalent of up to 8-channel memory, which not even server CPUs of the competition provide. The SSD gets easily 7 GB/s reads in my testing. Both Windows and Mac have a working memory compression algorithm and a sister post claims that it works better due to hardware acceleration, which I’m inclined to believe. Memory compression on Linux is a mess as you cannot keep compressed memory pages in physical RAM, instead forcing you to partition the memory and manually handling how much and what to put in compressed zram.

Low memory situations are thus handled better than on other operating systems. Memory and memory pressure are neglected concepts in the competition, both the hardware providers and operating system providers.
