2 hyperthreading cores vs. 4 normal cores of equal speed.?

Say you have a dual core machine with hyperthreading-running at, say, exactly 2ghz each. then say have a perfect duplicate of those cores, but you have four of them on a single chip, and the two chipshave all the same specs with the exception of hyperthreading.



so to clarify, you have 2 cores with hyperthreading @2ghz each

and you have 4 cores without hyperthreading @2ghz each
