Core Duo 1.83GHz vs Core 2 Duo 1.83GHz

DanG

I've googled and can't seem to find much info.
Is there a noticible increase in performance going from the CD to the C2D, specifically in a laptop?

The boys at AnandTech did a comparison last year. Here's the link:

Seems that core 2 duo > core duo. Read through it and see which one suits your needs better.

If you stick with the same speed, not really, a few %.
The real advantage with C2D is that you can move to larger cache, faster memory, and faster CPU.
My daughter has a lappy with a 2.0GHz CD, and 2GB 667 memory, my desktop C2D at 2.2GHz with 2GB 800 is enough faster to notice. I have run limited tests, I am estimating that it is 25%. I know that a part of that is the chip set (965 vs 945). I tried to avoid drive sensitive tests since mine are much faster.

Also, I think all the Core Duo are 32-bit and all the Core 2 Duo are 64-bit. I may be wrong tho.

Mason you are correct the C2D is 64 bit ready and the CD is not. Also Edcentric is right about the FSB & Cache "4MB instead of 2MB" but performance wise I think the max difference between the 2 CPU's is about 5% to 12% not much more...

ok, I was just wondering if it's worth ripping apart 2 laptops to upgrade mine, but if it's not a huge deal, I'm not going to bother.

Thanks guys.

well in most cases, if it is a HP, Acer, Emachine, Toshiba, Gateway or any other low level brands than no... Most Dells and ASUS, Alienware and brands of that state have easy access to the CPU's, and they could be upgradeable.

they're both dell inspiron 6400's. I checked out the service manuals, and they seemed fairly straight forward. We'll have to see how lazy I am next week.
