Re: many of the guys on SI have serious problems understanding the subject of TDP. pgerassi for example tried to convince everyone that X2´s power consumption would be lower than Yonahs, and that this 89W part would be suitable for t&l notebooks, but Yonah somehow wouldn´t be. Many others like Petz actually agreed with him, no matter whatever evidence to the contrary and logic I brought up, no matter how idiotic pete´s points got. Incredible.

How does Pete explain the measurements at Anandtech? Does he still believe his theories when the system power consumption tests using Yonah dissipate 36W lower power under load than the lowest power X2 - especially when Anand says that Yonah was run with a desktop powered chipset (945G)? You can almost subtract another 10-15W just by switching the Yonah system to use a mobile optimized northbridge. Pete will have to do some incredible dancing to push his theories in light of this. But I'm sure he'll try. :-)

P.S. were you accused of FUD when you brought up your logic and evidence? I think that's the tragic part of trying to explain things to these guys.

Keith, yeah, not everyone has the same flaws but we sure all have some. Tx for providing a bit of contra weight. OTOH the A64 X2 3800+ is a desktop voltage part. A only slightly hypothetical 4400+ that is volted down might help quite nicely to get close to par with this particular version of Yonah measured by Anand. So Pete/Petz's points might actually not be entirely out of wack. Lastly although it's not useful now DDR2 might help AMD based systems towards slightly lower power when it's actually released onto the market.

Anyways, I thought power consumption of the 3800+ and Yonah were quite close at idle, and that the difference between idle and load was quite close for Yonah.

Dear Keith:

Yet I was proven right! There are sub 35W DC Opterons in the public domain sold to real customers. Yonah uses more power than that. No test has yet been performed to see how much the Yonah actually used (just the system power in one preview prior to any actual sales) even by measuring what that sample Yonah (probably was cherry picked for reviewers given Intel's past track record) actually pulled from the 12V VRM input. Yonah isn't even out yet and you compare it to desktop CPUs made much earlier and on a MB with much higher capabilities than the Yonah MB (it uses a different 479pin socket so even the MB it uses isn't out yet).

No you are the one who is making laughable comments that didn't prove true. Like 89W Opterons aren't good enough for laptop use. Wrong! Your logic failed! Your so called evidence is refuted by real world results. Thus your points must have been idiotic. There are A64 X2 3800+s (and higher) with TDPmax less than 35W in the field bought by real customers from real retail shops in the real world.

Your points are lacking in credibility. They failed in the present and that is the real test. You can get 939 pin DC Opterons and A64 X2s in laptops using less than 35W TDPmax right now. Since 35W (and 25W) Turions are in T&L laptops, AMD could make DC Turions right now (just place the same die (the DC opteron or A64 X2) on 754 pin mobile packages) and those would fit T&L laptops. The timing of the DC Turion release is up to AMD, since technically, they can do it right now, your incredulity not withstanding.
