GlobalFoundries roadmap slips?

[Mechromancer]

AMD has a lot of headroom on 45nm with Revision C3 and Revision D silicon yet to come. AMD has yet to even implement high-K dielectrics or metal gates on 45nm. As AMD has limited resources, they need to concentrate on getting that tech to us ASAP so 32nm can wait.

Focusing on process tech really is focusing on the wrong metric to measure AMD with too. What matters is are they on track to release their next gen microarchitecture on time. Orochi/Interlagos (Bulldozer family) are 2011 parts so as long as they're not pushed back anymore than they have been, all is well.

can it? why is high k so important? more important than 32nm? why?

Yeah SOI is fine. There were doom and gloom stories about SOI before 45nm but after seeing how good it is at 45nm there are high hopes for it at 32nm too.

AMD will not implement high K in 45nm, IBM said its not important for 45nm, so did AMD for 45nm but 32nm is suppose to come with High K and IL.

With high k implementation each chip will cost more to make than rite now other than the initial costs. But the wonders like i3 with low lowpwer consumption would be hard to make without high k. 80W fully loaded is insane .... AMD better have a Athlon x3 with low loaded and stand by consumption but most likely it will eat like the x4 does

SiO2 can't scale any more, it is as thin as it can go. High-k restores that scaling, and brings PMOS closer to NMOS in performance (that's the metal part actually).

At first, of course they have to say that they will be able to catch up (or almost catch up) to Intel... and then of course it is postponed...

[RussC]

Its looking more and more to me that BullDozer better be the cats meow, or AMD may really be kaput.....?

SOI and HKMG adress different things. One takes care of the gate leakages and one of the channel leackage...

With smaller processes the gate leakage overwhelms the channel lakage. SOI was an advantage when the channel lakeage was bigger then the gate leakage at bigger process structure, but now that we have gates that are only a view atom layers thick, gate leakage is the major concern.
