When I say this, I mean like a car for example. A 50 horsepower engine is going to be faster then a 25hp engine. How does this work in graphics card? Is it something to do with core clock speed?

Just wondering because im buying a overclocked 7850 card and I'm trying to compare it with others.

Hoped this wasn't to confusing, cianc

Hello.
Actually, same happens at GPUs.
Most of the times, in the same generation and brand (AMD or Nvidia) of GPUs the number of cores will tell you, how much powerful a GPU can be.

With some more analysis, you will see that there are a few things more:
1)core number
2)clock speeds (mhz)
3)memory bandwith which has a few sub categories:
a)memory type: DDR3 or GDDR5
b)memory bus: pe: 256bit will be better than 128bit
c)memory mhz

But in the end, especially in gaming cards (like 7850 and 650ti boost, and faster ones) core numders will give you how much powerful a card is.

Same happens in cars too ;) hp isn't the only thing that makes a car fast. Its the weight of the car, the aerodynamics, the number of hp that goes to the wheel etc etc

edit: If you are refering only to 7850s you can see which is the best just from the core clock.
edit2: be sure to buy the 2GB version also :p. 1GB for gaming died a long time ago...
edit3: I remembered that TechpowerUp had a list of the versions of each GPU. So here is the list for HD7850:
AMD Radeon HD 7850
Below is the list if you are bored to look based on which has the bigger core clock:
