Yes. I think the point of the article was more that people don't understand where HT/virtual SMT gets its speedup from.

- magicalhippo 6y agoFrom the very start I've always heard HT being good for memory-bound applications. That's how it was explained and marketed. Some years ago I worked on such an application, and we got a ~80% speed increase going from 4 threads to 8 threads on a 4-core with HT enabled. I wouldn't expect compute-bound applications to get anywhere near such gains. Makes me wonder where those with a misconception got it from.
