Hello aguilera2000 ,
Any chance you have a website where you are seeing this information??
I am only aware of the Intel® Pentium® Processor E2160. It maybe possible that the site you are seeing this have it incorrectly listed as a Core 2 Duo.... is is a Dual Core processor.
It's the same processor. Some online stores incorrectly list Pentium Dual-Cores as "Core 2 Duo".
