- supermatt 5y agoIts all very interesting. I wish apple would be less tight lipped about how it all works together. Theres so much guesswork because we don't fully understand how the new arch is being utilized.
- marcan_42 5y agoSwapping isn't CPU-intensive, and Apple also implemented the memory compression as custom CPU instructions. Swapping is I/O intensive, and these machines have stupid fast SSDs which is why they can get away with it. When you think of swapping as slow it's not because it eats CPU, it's because it blocks on I/O.
