Each of these names refers to a different line of chips with different architecture. .

The Core 2 is the latest from Intel and currently holds the lead on performance and performance-per-watt for consumers.

The Core was the short-lived successor to the Pentium M line of low-power mobile CPUs.

The Pentium D was a stop-gap solution to AMD's dominance in dual-core processors, superseded by the current Core 2 line.

The Turion 64 X2 is AMD's line of dual-core mobile processors directly competing with Intel's Core and Core 2 mobile lines.

What the guy above said is pretty much your answer. The same goes for Desktop processors too.

You can think of core 2 duos as the true successor to the pentium dual cores really, dispite the couple of less popular models in between. They operate similar but faster and better thanks to their improved archtecture. The AMD x2 chips are dual core chips from intels rival AMD. They usually have less cache than the equivelent intel pentium chip but can in most cases hold their own against their rival. AMDs are usually a little cheaper to replace too. Though Pentium chips usually perform a little better when involved with any kind of file or audio / video compression or encoding.

Most laptops containing pentium dual cores will be upgradable to a core 2 duo as the socket is the same. My Laptop has a pentium dual core in it and it is pretty nifty.

Just dont get a celeron if you dont want a slow machine.

Tech guys... Check out Intels new i7 chip for the future of processing technology.
