dual core v.s Hyperthreading

[letulechuga]

can someone explain to me what the difference is?

Hyperthreading splits the load for one core; dual core is 2 separate cores; most dual cores don't have hyperthreading support because with 2 cores splitting the workload, you don't need it.

Hyperthreading simply uses special techniques to keep the insanely deep P4 pipe filled with instructions by allowing not only out-of-order execution but also out-of-thread execution, thus making it "look" like multiple cores even though all it is doing is preempting one thread while it's stalled in the pipeline.

so obviously the 2 cores are more efficient? but shouldnt intels be better then? the x2 however outbenches the 8xx series.

The X2 and 8xx series are both dual core processors.
