Chipguy: I read your post. Your argument that the volumes of fused CPUs is tiny is quite wrong given the large volumes of them in the field, even now. If a majority of these are due to simple segmentation, Intel can and does make different die designs to save money. There are 4 such for 65nm C2Ds, SC and no L2, SC 1MB L2, DC 2MB L2 and DC 4MB L2. There is also one for 45nm, DC and 6MB. So Intel does do smaller variants when the volumes are high enough. There are large volumes of E21xx CPUs sold and every one has to be a fused off DC 2MB L2 variant die. Enough so a DC 1MB L2 variant would save Intel quite a bit of money. Since Intel hasn't done such a variant, it is likely that most of the fused E21xx CPUs would not work as DC 2MB CPUs. And that implies poor yields on the DC 2MB C2D CPUs. This is further reinforced by the large number of large capacity 65nm fabs Intel has. So overall your post is wrong and even if, taken only to mean that the a tiny fraction needs to be fused, not likely based on past history and current sales. Pete
