Core 2 duo verses dual core

Hello abk;

Dual core is too vague. It covers everything from 2005 AMD Athlon X2 to 2012 Sandy Bridge Core i3.
Did you have some specific models you want compared?

"Dual core" is a generic term for any AMD or Intel CPU with two cores.

Intel's 1st dual core CPU was the Pentium D series released back in 2005.

AMD's 1st dual core CPU was the Athlon 64 X2 series released back in 2005.
