what is better ??

Intel Centrino Core Duo
AMD Turion 64 X2
Pentium M
AMD Mobile Athlon 64
Intel Pentium 4

And of course i want a dual core...but can u rank these in order..cause i can't spend alot, but want the most for my money.. and if i left anything out can u put it in the ranking please!!!

Centrino Core Duo (dual core, duh)
Pentium M (it's designed for mobile enviornments)
Pentium 4 (not designed for mobile enviornments, also not dual core)

If you're looking for more bang for your buck, go AMD.

thanks for the quick reply..
would u take a lets say an AMD Mobile Athlon 64 4000+ 2.6GHz
or a intel Centrino Core Solo T1350 1.86GHz

Not considering battery life, I would probably take the Athalon because of speed. 64 bit problems seem to be diminishing. But it would mostly depend on the battery life the laptop gets with the Athalon. If it only gets 2 hrs with the Athalon and 4 with the Intel, I would go intel.

Wait for others to come on and weigh in, there are people who know a ton more about hardware than I do.

do the new intel duo in laptops..offer a highr Fbs like they do in desktops

eitehr the Core2 Duo, or the TurionX2.... hmmm.. i would go with the Centrino. it is based on teh new Core Architecture, is more energy efficient, and produces much less heat than the AMD one does. Also, it has much better performance. The new Core2 CPUs far outperform AMD at much lower clock speeds, lower heat and power
