Rick, you can't go at engineering but go after physics (owned by Mother Nature).
When these things are processed it's not possible to control all the densities of the channel wells and traces. Due to molecular differences and flow the etching process can sometimes erode too much causing caverns under the layers between the resist and exposed semiconductor shrinking the trace or transistor stack. Any of these can cause the component to be too thin to handle current of the heavy creating lag and in some cases shorted. Most of the disc edge stuff I'm sure is chunked. This is the first production run. Soon a second run will adjust the troubled spots attempting to improve the mask which might prevent some losses. This happens all the time, it just takes getting out enough stock before the change is implemented. In the mean time take advantage of moving bunk stock that would other be waste. Again, todays manufacturing is focused of reducing scrap which is a big loss in this case.
I too would love to see a true dual again at 45nm. It would probably kick arse.
Another thing, AMD does have it's hands on narrow transistor tech which will increase the density of RAM.
For now, enjoy large cashes because we had them taken away in AM2 before Phenom!
