I bought a new Dell 745 desktop system. I paid for Core 2 Duo 2.1 GHz, but the system is showing Core 2 in the Properties. It should display Core 2 Duo instead of Core 2.
Are Core 2 and Core 2 Duo the same thing?
Core2 is the name is the name for a microarchitecture. It encompasses a whole CPU family
There are single core CPU's based on the core2 architecture.
There are dual core core2 CPU's based on the core2 architecture. (Often called core2 duo)
There are quad core core2 CPU's based on the core2 architecture. (Often called core2 quad).
Thus calling a core 2 duo
a core2
is perfectly valid.
Analogy: (cars with engines)
A car with a 1 horsepower diesel engine is diesel engine based.
A car with a 2 horsepower diesel engine is also diesel engine based.
A car with a 4 horsepower diesel engine is also diesel engine based.
In all cases it is safe to call the car 'diesel engine'/'core2' based.
All this means there is nothing obviously wrong.
However you can easily check things:
First see which CPU you are supposed to have.
(Go to the Dell site and enter the service tag. That should show you all the details of your optiplex).
Then either:
Once you have the model of your CPU you can find more information about it on this site.
