AMD's Bobcat and Bulldozer

[informal]

Yes i already read the artciel...



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.

IPC will go down?Are you serious ?
Having more underutilized units is bad.Having less units that are constantly fed and always have something to do(the part you made bold) will make the "IPC",the relative and mostly meaningless number (that is 99% of the time <=2), higher. That's the whole point of this machine.
