got 4/5. Got the SMT one wrong.

Isn't it true the Pentium 4 didn't have SMT? (the first ones without HT?)

4/5? You mean you got one wrong or 3 wrong. There are 7 questions in total.

Pentium 4 had SMT. SMT == HT. Saying that SMT wasn't there in parts without HT is a bit circular.

Thats not what he meant. Pentium 4 had two underlying core architectures. NetBurst and Perscott. One of them didn't have HT so the author is incorrect IMO.
