All the improvements done together with the frequency increase are meant to compensate the 3rd unit. You have the information in the AMD slide ( ...without significant loss on the serial single-threaded workloads components ), you also have the comments of M. Alsup ( ...and
loose a little architectural figure (5%-ish) of merit due to the
microarchitecture ). It all fits together now, irrespective of what marketing is trying to portray.
Someone please explain once more to these two terrace and savantu that when AMD speaks of tradeoffs, they do so on Bulldozer vs. Bulldozer, meaning 5% less performance on a BULLDOZER core with 2+2 ALU/AGU vs. a BULLDOZER core with 3+3.

I think some people can just be too blind in denial or wishful thinking, plus it drives me nuts how one can hug the nuts of one single company so tightly it feels like were talking about football rivalry.

You should grow up and learn to support healthy competition above all, you have NOTHING to gain if Bulldozer completely fails.
