I would assert that, at least in the case of the P4, there IS a "major
core", as the 2 subcores share L1 and bus controller access, as well as
several other parts of the chip.
I beleive this is to some extent the case in the Power4 modules - that
each module contains resources shared by the execution units. However, I
might be full of it, and since there are plenty of @ibm.com's here I
expect to be corrected shortly....
