I use to know a lot about this. Which I don't anymore. I can tell you that the core duo for laptops is an order version with the newer ones being the core 2 duo. I also noticed that laptops can have a single core duo. I'd look it up if I wasn't about to leave.

Not really, has a lot about core 2 duo but nothing related to core duo.

I assume the core duo I have is based on the core achitecture..

The differences between the core duo and the core2 duo are:
- CD has 2Mb L2 cache, C2D has 2 or 4Mb
- CD supports 32bit instructions, C2D supports 32 and 64bit
- C2D is a lot better than the CD on multimedia applications due to core improvements - detailed review here


Overall I'd say that for the office-type apps there is next-to-nothing in performance improvement, at the same clock of course.
For games, encoding and other memory intensive tasks like archiving the improvements can be quite important.
In video encoding I think the C2D is twice as fast as CD at the same clock.
In games the C2D with 4Mb L2 cache are very good due to the extra cache and also due to the memory prefetchers implemented in the C2D

If you want a more proffesional look on the architectural differences look at the article above, it's quite good and easy to understand.

Looks like I was beat too. And I was just going for links. Sad. My network connection seems to be acting like dial up this morning.
