What is Pentium(R) dual-core?

I get the message Core Duo and Core 2 Duo. However, was looking at Dell.com and they propose THREE options:



#1. Intel(R) CoreTM 2 Duo T7200 (2.00GHz, 4MB L2 Cache, 667 MHz FSB) [add $250]

#2. Intel(R) CoreTM DUO T2350 (1.86GHz, 2MB L2 Cache, 533MHz FSB) [add $40]

#3. Intel(R) Pentium(R) dual-core T2080(1MB Cache/1.73GHz/533MHz FSB [Included within Price]





So what is this number #3?



I have a Core 2 Duo very soon. How much different is #3 from that? Big difference in show? How hot it runs? Battery Life?



Regards for any help!!!

From reading, its a budget model of the Core 2 duo base off the conroe-l...
i muse there's not much of a difference. they all own dual processors but the higher GHz the better. i own intel pentium D core duo 2.66GHz
