Hi, The only thing that was really going for P4 is that it can be clocked extremely fast. But the fast clock cycle led to an extremely long pipeline (over 30 stages!). HyperThreading (the technique that simulates two threads running at once) is really only useful in certain situations.
Core 2 duo went back to a P3 design (i think), added some current features, and put two cores on a single chip. This architecture is better than P4 by far and is more efficient, which is why you are seeing a high performance degregation when compared to the Core2 duo. I'm taking an advanced computer architecture course this term and we went over these two architectures.
