   //EDIT
   That came out sounding harsher than I meant it to. What I meant is "why are these temps surprising?"

   23 Sep 2004 ~ 6:39pm Geeky1 Well, first, the heat dissipation issues that the Prescott has are not nearly the problem that everyone has made them out to be, and the Athlon doesn't seem to have a major problem either. The only company that really appears to be having issues right now is IBM.
   
   Regardless, this was to be expected. It's a byproduct of moving to a 0.09 micron process.

AMD is using SOI which helps with the leakage. With less leakage there isnt the need to increase the current like Intel had to.
   
   Looks like AMD was able capitalize on the die shrink like in previous die shrinks unlike Intel.

   24 Sep 2004 ~ 12:51pm muddocktor What I find interesting is that reading in the translated article, it appears that these first 90 nm A64's don't have SSE3 extentions. From what I gather in the translated version, which is kind of scrambled to say the least, is that we won't see SSE3 support to rev. E 90 nm A64. If there is no support for SSE3, then there's no reason to even consider these early 90 nm procs as they probably won't overclock any better than the present 130 nm parts and the 90 nm procs run hotter than present procs too.

   May see the Winchester core obviously compared to the NewCastle old core hot 1., but differs certainly is not very big, probably only some 3-4 distinction, looked like changes over to 90 奈 rice although obviously can make the K8 processor temperature rise, but actually has not liked Intel Prescott to be fearful, believed is when Athlon 64 itself the arteries are not certainly high, after therefore changes over to 90 奈 rice certainly not to appear the too big leakage like Intel.

   higher temps on a .9 chip dont mean it is "having problems" - it means there is less surface area to dissipate the heat that is produced.
   
   intel's prescott also doesnt show any problems with their .9 process either - its a massive long piped chip, and as such is going to be less energy efficient. its not necessarily their process. look at their dothan. the same process, not hot. ergo, no problems with intel's process and not necessarily any problems with amds either.
   
   you can see the reduction in amd's power use over 130nm by checking google, techreport is one such site that pops up.
