i'm a little confused by the reply you gave here - did you mean yes to my question (re: the same socket)?
In my thread here
you say that they use different ones...
The thread you have is asking about do desktop core i7 920 and laptop I7-820qm cpus use the same socket. That would be no.
In this thread, these cpus are using the same socket as these are both mobile cpus. There a 920 for both desktops and laptops. Now to tell the difference between the 2 is looking for letters like qm at the end.
Core i7 desktop cpus, dont have lettering at the end except for the upcoming core i7 980x. Example: core i7 920
Mobile core i7 cpu have lettering the end. They'll nomally have the letter M in it meaning moblie. example: i7 820QM & i7 920XM
Hope this clears some things up.
