  From the HardOCP review: "Certainly moving to watercooling helped us out a great deal. In fact it is hard for us to recommend buying a Prescott and cooling it any other way."

  I am curious as to why the UT2k3 botmatch scores dropped on all CPU's... Different map?

  Sorry errata on #20 that was 3.0 Northood result is out of kilter with other cpus in dtata analysis sysmark 2004.

  JFK,Vietnam,Nixon,Monica,Bush/Gore,Iraq and now this! - what is going on with the leader of the free world.I hope it overclocks well- that's all that's going for it. Maybe Intel should rethink their multiplier locked policy. AMD must get in there and profit. I still dont understand why the caches are running at half the latency as Northood if they are the same speed and structure? Is it as a result of a doubling in size for the same associativity?
  
  Good article- needs re-rereading after digestion. Last chart in Sysmark2004 (data analysis) has 3.0 Prescott totally outperformed by 2.8 Prescott and all other cpus. Look like a benchmark/typing glitch.

  first the error:
  pg 9 -
  The LDDQU instruction is one Intel is particularly proud of as it helps accelerate video encoding and it is implemented in the DivX 5.1.1 codec. More information on how it is used can be found in Intel’s developer documentation here.
  
  No link?

  "What's the power consumption like on these new bad boys?
  
  Is anything less than a quality 450watt PSU gonna be generally *NOT* recommended?? "
  
  I'm going to guess a clean running ~350W or so should suffice for a regular system, but I'm not positive with these monster gfx cards out rite now...
  
  "Any of you know what the cache size on the EE's will be?"
  
  If your talking about the Northwood (the p4c's are still considered northwoods, no?), its 1mb I believe.
  (still finishing the article. man i love these in-depth technical articles)

  I agree, some info on power consumption please.
  
  Thanks for the article, by the way.
  
  I guess we'll have to wait and see how Prescott ramps in speed versus 90nm A64.

  Much better than the P4's origional launch...
  
  All I want to know now is what AMD is going to do soon... They'll probably counteract Prescott with high clock speeds but when and by how much is what matters.
  
  Any of you know what the cache size on the EE's will be?
  
  Also, the final CPU's based on Northwood are kind of like a car with the ratio curves or whatever they're called, but basically after a point of revving, going any higher doesn't give you as much of an increase in speed as it would at a lower rpm increasing the same amount.

  AMD's roadmap shows a 4000+ Athlon64 by the end of the year... which is the same as Intel's. They are aware, im sure.

  Things are gonna get hairy in '04 and '05!!! My take is that AMD nees to get their marketing up-to-spec or the high-clocked prescotts are gonna run the show.
  
  I have a question for Derek and Anand: What kind of temps does the prescott run at? what type of cooler does it have? (there's nothing there to support or refute claims that the prescott is one hot potato)
