JF, I was wondering, since the Bulldozer architecture is modular, and previous slides have shown the next gen bulldozer to be upto 10cores.

Why do a 10 core, when it would make more sense to do a 12 core (in my eyes) so then a rectangle die can be cut out instead of an odd shape?

10 core I assume would be:
[x][x][x]
[x][x]

and a 12 core would be
[x][x][x]
[x][x][x]
