They aren't intel netburst architecture. Someone else is free to
implement hyperthreading (SMT) without a shared pipeline after all. Not

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.
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.
