Wow, reading this stuff is really hilarious. so many taglines and key words without the faintest comprehension of what is really going on. just a bunch of people out to say why their chip is beter than the other guys.
First off AMD does have performance lead on many applications. They also have a power lead. that is known.
However, to blindly say that since AMD, using a 90nm SOI process, is lower power than the P4 EE on a 65nm process means that AMD's 90nm process is so incredibly that much better is just raising a big flag to say "look at me i haven't the faintest clue what i'm talking about!!"
the fact of the matter is that AMD's power lead has everythign to do with their clock speed, not with their process. higher frequency, higher power. look it up in any 1st-year electronics textbook.
If you want to make a process comparison, therefore, compare centrino. Intel's Yonah processor (Core Duo) to AMD. They are much closer frequency-wise.
Here all you AMD people will say "yea, but that's a mobile processor, that's not a fair comparison!". so? neither is the AMD-to-P4 comparison when measureing the efficiency of the process.
So if you think Intel isn't leading the process-technology or manufacturing revolution just cause your Athlon FX runs warcraft at 20fps faster than the P4, you're again, waving the dummy flag.
Intel has over 2M sq-feet of cleanroom space. They are spending $3.5B to build a production FAB for a fully-proven, chip-in-hand, 45nm process technology they alrady developed in their research fab. And they already have 3 full production fabs (using 300mm wafers) on 90nm technology.
AMD has 250,000 sq-feet of cleanroom space, they are just now getting their 300mm wafers online (Intel had this in 2002), they are using a 90nm Silicon-on-insulator process (that incidentally requires more-expensive wafer stock with substrate "stuck" onto silicon dioxide, thus eroding profits) . And as far as all of you saying how they are "working with IBM on 22nm process"...if you think that Intel isn't working on the next process, hell, the next 4 processes, without help from outside companies, you're sadly mistaken
See these links from 2003! Paul O. showed photos at IDF of prtotype transistors (in-hand) all the way down to 22nm

and the following press about it:

Intel is the world leader in semiconductor manufacturing. period. That is their power. if you think that AMD has *anything* on them in that regard I eagerly await hearing what that might be.
Also, there is more to process techology than power, or performance. There is cost. Intel, or AMD for that matter would gladly accept the exact-same chip on a smaller process, with no improvements whatsoever. In fact, that is *exactly* what intel did going from their 90-nm to 65-nm P4 processors. there was no performance gain there, only the process change. So why do it? simple. lower cost per processor. Fabrication goes through a number of steps per wafer (lithography, implantation, NiO2 deposition, cleaning, SiO2 growth, poly-dep, etc...). the time it takes the wafer in each one of those steps dictates how many wafers you can put thorugh the fab. If you can get more processors (dies) per wafer, great, because it doesn't change how many wafers you can get through the factory - just that you get more chips per day, and thus you increase your capacity, and lowers your cost/processor (which is then sold at the same price or more).
Intel leads the world in that regard. AMD has to go on IBM's research coattails, announcing joint-partnerships and so forth about "technology breakthroughs " that intel announced years earlier. sometimes about technologies that intel already has in production.
So there are many factors at play here, but as far as the title of this thread, If nothing else, just realize that lower-clockspeeds means lower power. It does not mean better process technology. A new process technlogy usually means lower power as well, but if you're gonig to compare that directly, you have to compare apples to apples. Right now, that's not available, since CoreDuo operatesin a 35-W TDP mobile envelope. Athlons are in the 85W desktop envelope, so naturally can be run a little faster, higher power, higher performance.
The true comparison comes with Conroe later this year. I can't wait to watch and see what the 65-nm process can really do at a lower clock speed.
