The new Pentium D processor puts two processors in one CPU. That means that the chip can manage two very distinct tasks independently of each other. This was introduced because it is becoming increasingly difficult to speed up the clockspeed on processors. While that will continue its being hampered by the technology used to reduce the size of the transistors and increase their number inside a processor.
So for example the Pentium D 825 has the equivalent of two 3 GHz processors on board.
Intel is adding HyperThreading to this. HT technology came out in 2002 adding two virtual processors to a single chip. The idea is that there is a lot of inaction inside parts of a chip during certain processes so recruiting this slack to do work as a second processor gives a computer more horsepower to work with.
Next up is: Dualcore HT chips. And of course Dual core chips will become quadcore and Octocore chips as the technology develops.
More info here....also be sure to click on the dualcore and dualcore with HT animated demo:
