Looks like AMD photochop goons messed up not only the CPU cores, but a part of IMC/NB area:



The structures, highlighted in the green rectangle, have been clone-stamped over and over again with patterns from the IMC/NB to the right side, to fill out (completely conceal) something equally important to the cores.

I can only speculate, that this is an L3 directory cache and routing logic, if we are to believe the four L3 partitions are private to each "module".
