This site tested the AM2 Athlon 64 X2 3800+ dual core CPU operating without a fan ! Core temperature was at 42C with the fan, without the fan, temperature rose to 49C.

"Core temperature was at 42C with the fan, without the fan, temperature rose to 49C."
You're confusing different tests, the 42C max with a fan were reached running an instance of SP2004, at full load.
During the fanless tests, it reached 32C at boot up, 36C after 1 minute. 42C were reached after 5 minutes and 49C after 7 minutes, at which point the test was ended. All that's while idling on the windows desktop.

Oh, and btw, they didn't test an X2, it's a single-core 3800+ processor they had.

1) The clockspeed was at 2GHZ, so it's not running at low P state.
2) It was a X2 3800, see pic
i'm not quite sure i understand the reason you post this up...
MOG Intel will be screaming in the dark, Paul may even take the money and do a dive of the high board.
"The clockspeed was at 2GHZ, so it's not running at low P state."
Probably true, doesn't change the fact that you're trying to compare a fully loaded CPU with fan to one idling without. (The real comparison is 36C for idling with fan, 50+C after 7 minutes without and no idea when it'll stop working/throttle/crash)
"It was a X2 3800"
I saw the pics and I saw the markings on the IHS, but from looking at the following shots, one can only see a single active core:

So while they seem to have had a X2 3800+ at hand, it ran like a single-core 3200+ (not the 3800+ I wrote above) during their tests. (I'm guessing it's a problem with the motherboard and/or BIOS)
The whole fanless test only makes sense as a test of the heatsink material and mass. And I'm not impressed by a 3200+ that reaches 50C in a mere 7 minutes while idling on the windows desktop.
My conclusion: Bad heatsink for that job. (or rather: One not designed to do the task asked of him)
Woodcrest looks much better than planned
The last part, less power, is the big one. I am told Woodcrest will be coming in with a 65W TDP. This is big news, and by no means a minor drop, it is on the order of 20%, and will most likely send AMD scrambling. Whatever magic Intel pulled off, well done. ยต\

AMD's dual core Opteron HE was 55 watt 9 months ago.
Read the report below:
http://issj.sys-con.com/read/117897.htm
2x dual core Opteron (4 cores), 8GB ram, 1TB HDD, total max system power 145 watts.
And I'm not impressed by a 3200+ that reaches 50C in a mere 7 minutes while idling on the windows desktop.
According to AMD, AM2 consumes 14 watts when running SysMark2004. Yes. They should have used a copper heatsink in the fanless test. Instead, they used the stock heatsink for a sempron 2500+ without the fan.
"AMD's dual core Opteron HE was 55 watt 9 months ago.

I did a search of 55 on the page, didn't find anything match. All I got is this:
"
Rackable Systems' new C2002 server, winner of the Best Server award, draws an astoundingly low peak of 145 watts in a configuration featuring two dual-core 1.8 GHz AMD Opteron HE processors (four total cores), 8 GB DDR400 RAM and one terabyte of SATA storage leveraging Hitachi 500 GB hard drives, with a mere 500 BTU/hour of peak thermal output.

"I saw the pics and I saw the markings on the IHS, but from looking at the following shots, one can only see a single active core:"
Did you see this page where it clearly shows dual active cores?
What you saw was temperature sensor measurements. There is only one temperature sensor for the CPU.
"What you saw was temperature sensor measurements. There is only one temperature sensor for the CPU."
No, what I saw was (a) CPU-Z with a darkened-out core selection, (b) the Windows Task Manager showing only one core and (c) only a single instance of SP2004 run to stress the processor.
Right now, I can't fathom the idea that the shot you linked and the shots I linked earlier came from the same install or even system.

Click at the "next link" on the first apge you linked and you'll get to the shot I linked.
That said, I agree that the credibility of the "under load" tests is in doubt. ;-)
"Click at the "next link" on the first apge you linked and you'll get to the shot I linked."
I'm sorry I wasn't clear about this, I was not questioning you, but rather the test as it's showing inconsistent results for what is supposed to be a single test-rig.
