Yeah, sorta ... it get's worse. For barcelona, AMD thickened up the gate oxide because of leakage problems (by about 25%, what this does is ruins the transistor switching speed.
This is harder to prove -- http://www.eetimes.com/showArticle.j...leID=202100946
AMD's brisbane/65 nm process had exactly the same gate oxide thickness as Intel's -- see (unlinkable) IEDM 2005 proceedings, AMD's 65 nm process paper (sorry, need to use a library for that one)...
So by thickening it up, they are trying to bring down gate leakage, but it is not going well by the looks of it.... Phenom at 2.4 Ghz is 125 Watts TDP... ouch. (BTW, you can email J. Boyd -- email in the article and ask if they thickened up, he will respond kindly as he did me)
