BTW, I doubt that what vasanth described could actually work. The situation of such independent instructions is rare enough that the coordination of distributing it to two CPUs (or even CPU cores) would drown out any advantage. Besides, that's what super scalar and VLEW (PowerMac and IA64 are examples of each) architectures are for.

well actually the core duo itself uses certain super scalar techniques.. so yes it has certain advantages and disadvantages of a super scalar processor...

and one more thing to consider in single core processors such as Pentium D etc is they achieving a higher clock rate with substantially longer pipelines when compared with core duo (31:14) and this itself reduces the performance of single core processors though they run at a higher clock rate due to bubbles in the pipeline..

so overall the core duo seems to outperform other single core processors in theory and is supported by various benchmarks tests

and some one mentioned abt power consumption, the core duo is one of the processors to have quite a low power consumption....
