Are the iMac i5/i7 processors 32nm or 45nm?

[0087215]

I was just wondering.

According to the Apple website, all the processors found in their iMacs are based on the 32nm technology? Is that true? As far as I know, the i5 760 and the i7 870, which are to be found in the new iMacs, are both 45nm?

Is it a false information on the Apple website?
I wish it was true and those processors were indeed 32nm....

45nm

Partially correct. The i5-680 (3.6GHz dual, "Clarkdale") is 32nm but the rest (i5-760 and i7-870; "Lynnfield") are 45nm
