iMac vs Mac Pro CPU

For a while I have been mulling over whether to get myself an iMac or a Mac Pro ...

Recently I came across a discovery. Apple, on their website, lists the iMac and the Mac Pro as "Core 2 Duo", along with the specific speeds.

HOWEVER, if you go to intel's website, there are different type of Core 2 Duo processors:

Desktop Processors:
Code: 
Model   Cache       ClockSpeed  Frontside Bus
E6700	4 MB L2	     2.66 GHz	1066 MHz	
E6600	4 MB L2	     2.40 GHz	1066 MHz	
E6400	2 MB L2	     2.13 GHz	1066 MHz	
E6300	2 MB L2	     1.86 GHz	1066 MHz	
E4300	2 MB L2	     1.80 GHz	800 MHz
... and Laptop:
Code: 
Model   Cache       ClockSpeed  Frontside Bus
T7600	4 MB L2	     2.33 GHz	667 MHz	
T7400	4 MB L2	     2.16 GHz	667 MHz	
T7200	4 MB L2	     2 GHz	667 MHz	
T5600	2 MB L2	     1.83 GHz	667 MHz	
T5500	2 MB L2	     1.66 GHz	667 MHz	 
L7400	4 MB L2	     1.50 GHz	667 MHz	
L7200	4 MB L2	     1.33 GHz	667 MHz

If I look at the iMac lineup, based entirely on the FSB and the speeds - I can tell that they are using the Laptop variety of processors. Now I know that it means less power being drawn - but what, in way of performance, does that mean? Obviously there are going to be differences, or else Intel would have simply opted for the lower power processor.

EDIT:
Does anyone know of a website comparing the two processors, their strengths and weaknesses?
Anyone know firsthand what the difference is like?
 
I don't think the MacPro uses a Core2Duo, but a Xeon Dual-Core (well, two of those!).

The Intel Core2Duo E6xxx class is the Conroe processor, a desktop model, which is not used yet by Apple in any Mac.
The MacPro uses the Xeon 5100 series, (Woodcrest) which is listed as a workstation, or server class processor. It's probably not a simple thing to compare a laptop processor to a server-class processor, but there should be something at one of the geek sites. Makes it more of a challenge when you compare the Core 2 Duo, to the dual-dual cores of the MacPro
 
Okay. I know that workstation and server class machines are a lot more stable - they are built to survive under stress loads.

I was checking a number of 'Geek' sites, and I couldn't see any such comparison .. they were comparing Mac to PC equivilents, but nothing like Mac Pro to iMac.
