I'm a bit disappointed by the marketing spin. They come up with a few examples where HT falls down, and use that to dismiss the whole idea?<p>I wouldn't mind if they had put it in clear and honest terms: a 20% improvement in performance is not worth the unpredictable chances of performance degradation. That's a fair engineering decision. But hiding behind what some Cognos consultant and some Technet curator have written online, really?<p>And I'm still trying to decipher the technical motivation from this answer: "Of course there are those that can say “well, things like SMT can be implemented inexpensively and don’t consume that much power.” To those, I ask you, historically hasn’t AMD been the one committed to deliver better value and lower power?  Why would we stray from our core principles?"
