I ran into this post on the old CNET forums today and I had to laugh (bolding mine).
First off, always remember an important Internet axiom: Your right to be taken seriously is forfeit if you quote Wikipedia.
Wikipedia is rife with misinformation, bad information, and flat out WRONG information. It’s made by people just like you and me, who may like to think we know more on a subject than we really do.
Case in point: you clearly do not understand the difference between logical and physical processors, because the Wikipedia article is actually correct, and answers your question.
He slams Wikipedia for allegedly being wrong about almost everything while saying it was absolutely correct on this topic. Dear Jimmy, wake up and face reality, Wikipedia is as good as any paper encyclopedia and it is way easier to check its references than those in a traditional paper encyclopedia. A good rule of thumb is that as long as it’s not a political or current events topic Wikipedia usually gets the basic facts correct. If the accuracy is important then simply check the references in the Wikipedia article and if they or the article needs fixing please help out by fixing it rather than complain and slam Wikipedia.
