AMD (and I think VIA) is the only CPU microarch today that does not use some form of SMT. Intel, IBM, Sun all do 2 to 4 threads per core. I like to see REAL cores more than anybody, but Sintel is absolutely correct. The amount of extra transistors needed to make SMT work is tiny compared to the gain in performance.

It may be unknown to most (especially Intel folks) that if you disable both TurboBoost and Hyper Threading on a Core i7, you get the same or slightly less performance than a comparable Phenom II. Auto Overclocking and SMT do wonders in CPU reviews LOL. AMD can clock with Overdrive 3.0 profiles, but they need a little SMT lovin' to go along with that. AMD should have jumped on SMT after they saw P4-HT years and years ago.
