Intel's Pentium 4 570J - Will 3.8GHz do the trick?

Power Consumption
To measure power consumption we looked at overall system power consumption and tried to keep as many variables static. There are some basic differences which we cannot get around, mainly that the 925X uses lower voltage DDR-II while the nForce4 uses regular DDR, but for the most part our results were quite controlled. We also included power consumption figures from 130nm Socket-939 Athlon 64 3200+ and 3000+ chips, which as you may know, do not exist. The reason we did this was to show the sharp contrast to the power consumption figures of the 90nm 3500+ we've included in the charts below.
We measured power consumption in two states: idle sitting at the Windows desktop and under load while running our Windows Media Encoder 9 test, which proved to be one of the most strenuous CPU tests we ran as it pretty much isolated the CPU subsystem.
The Pentium 4 570J tops the charts as the heaviest power consumer out of our collection of CPUs here, which is no surprise. Since the 570J here is a different chip than the other Pentium 4s, its not too unsual to see slightly lower idle power consumption given that different chips in the Pentium 4 family can have different operating voltages.
We can't wait until AMD brings more of their Athlon 64 chips down to 90nm next year so that we may have an even cooler running Athlon 64 4000+.

why do you no longer overclock?you know users will do that. What if this processor was dialed up 10%, it would clock at 4.18Ghz and could run faster. I think the performance tales would be far different.

Well the CEO did step down a few days ago. I hope we see better management soon. This is an embarrasment for Intel. Ever since the A64 came out, Intel has been releasing backseat products.IntelUser2000 - Monday, November 15, 2004 - link
No, its that most of you guys are AMD biased. Say Intel does release a high-performing Pentium M architecture based chip. Then you guys will just shut up and say nothing else. If AMD comes with 5% performance lead, AMD is thought of as GOD or something. Probably even greater. And about BTX, Pentium M does run pretty cool, but at 21W, that was equal to initial 0.18 micron P3's. Actually some of the DESKTOP P3's had ~15W TDP. I heard 286's and 386's had less than 5W TDP. Cooler, and faster is always better. Granted you may not need as much if your processor runs hotter, but still its necessary. It's also mentioned that since quiet PCs are gaining popularity, BTX can help a lot since it will allow graphics cards to have smaller fans.Another 3.8GHz P4 link: http://www.tomshardware.com/cpu/20041115/index.htm...
Quite contrary to their 3.6GHz throttling article, they seem positive towards 3.8GHz P4.

#35,Do you know that the long post of #21 is the author of the article you just read (which is way longer than any post) and the owner of Anandtech? Do you see the post is from ANAND Lal Shimpi? And that his post was in response to the other long post which Anand saw as important enough to respond to.
I enjoy all the comments on this site, long and short. It gives readers a sort of "behind the scenes" look at hardware and software. I think there should be no restrictions as it currently stands.
Keep 'em coming. Go Anandtech :)

Based on #32's link, it would seem that the P4's would decrease in performance during sustained use with an average user. So unless you're an enthusiast, you would not see the full performance of any of the new P4's.Alphafox78 - Monday, November 15, 2004 - link
There should be a size limit on posts...GTMan - Monday, November 15, 2004 - link
Does the EDB functionality lower system performance when it is turned on?Auteur - Monday, November 15, 2004 - link
#12:The only reason HardOCP uses DVD2AVI in their bench marking suite is its the only Divx front end that runs faster on AMD cpu's than Intel's. Its a dead app (the author no longer updates it) that can't IVTC, deinterlace, clean or sharpen video. Its great for demuxing audio and thats it.
Intel's chips dominate when you use the popular front ends like AutoGK, Gordian Knot or Xmpeg. Read Doom9's forum if you don't believe me.

Did you read the article at Tom's Hardware this weekend about the thermal issues with the Pentium 4 3.6 GHz?http://www.tomshardware.com/cpu/20041114/index.htm...
"The Heat Can Cause Intel's P4 To Throttle And Damage Over Time"
I would expect that this issue is even worse for the 3.8 GHz.
