They have multiple cores per die with multiple SMT units per core. And it's very effective for J2EE websites and similar: short, mostly I/O bound code that doesn't take a lot of time.They aren't intel netburst architecture. Someone else is free to implement hyperthreading (SMT) without a shared pipeline after all. Not sure how Sun (or IBM for that matter) do theirs.
The point is that generalizations such as, 'A vendor is incompetent if they don't ship HT off' is just retarded because even on a Xeon, HT can have noticeable benefits for /some/ serving tasks. Not all, but some.
