Yes i already read the artciel...

The 3rd ALU does have some performance benefits, and AMD canned it to reduce die size, but AMD mentioned that the 4-wide front end, fusion and other enhancements more than make up for this reduction. In other words, while there’s fewer single thread integer execution resources in Bulldozer than Phenom II, single threaded integer performance should still be higher.
The improtant part is other enhancements.

4way wide frontend is wide, but alone its useless if you can't process the ops fast enough, so the solution is higher clocks speeds aka turbo.

Again i said, its highly likely that bulldozer will have higher singlethreaded performance, but IPC will go down compared to a single deneb core.
