Zacate is 40nm, it's impossible to have one part of the chip at 40nm and another in 28nm. It's one or another, but not both.
Llano will be interesting though, it's at 32nm and have 6 times as many shaders as Zacate, and will have 4 enhanced Phenom II cores but without the L3.

And about that IPC rumor, much in BD has been streamlined for as low amount of trannies as possible, and sometimes they made a performance trade off to lower the die size and enhance performance per watt or performance per mm˛.
So it might be a very efficient processor per watt, or per mm˛, at the cost of IPC. But it might be so that the other will make up for this trade offs.
Anyway, these enhancements aloow 8 cores at a relatively small die, and they might allow a high frequency design which is relatively cool. Might mean 4GHz+ at introduction.
