.. should have written "making the cpus run hotter and clock lower and harming single-thread performance without significantly increasing total throughput, sometimes even harming total throughput" - and making it harder to see how much *actual* cpu is being used by a process (a process seemingly using 50% of a physical core might actually be using near 100% of a core, but you can't see it in htop because HT makes it look like 50%/the-ht-core-looks-ready-to-go-even-if-it-isn't) - comparatively AMD's SMT seems to nearly always increase total throughput.
