The AMD system architecture is a legacy design going back to the
first K8s. Their cache architecture is what they can design in the
process technology available to them. The two-fer of two 8 core
chips in one package with the disadvantages of that (as the paper
said they are already taking the hit from being a two way system
in a single package) is the result of chronically not being able to
design a decent follow-on to the K8 core.

I don't think it is an issue of erroneously thinking this was the
right way to go but rather doing the best they could with what
they had available to them. It's hard to compete against someone
who is at the top of their game and has higher R&D spending
than you have total revenue. :-O
