You don't have to tell me, my stock XFX 4890 runs on the toasty side as it is now, I shudder to think how a nearly 400w heat load on air cooling would work out... Then again perhaps it's time for the first ever GPU to have a waterblock as it's stock cooling solution. Though a few newbs would undoubtedly think it's just a new fanless GPU.

My guess, this is merely ATI throwing out some false information. It wouldn't be the first time...

lol isnt evergreen supposed to be super power efficent haha, thats pretty good consindering a 4870/90 take up about 200 watts.

I hope they still get a 5850x2 out the door fairly quick, they can probably afford to hold off on the 5870x2 for a few months.

That is pretty high if it's true, but it's an extreme graphics card and therefore you would expect a very high TDP, maybe not that high but not far off it. It wouldn't surprise me much if this was close to the truth.

Thats what I was thinking. This makes no sense but it is Fud....

But this could be AMD trying to downplay their(possibly monstrous) 5870x2 and lull nvidia into a false sense of security as they did with their original R700 arch. Which if you recall, they(AMD) leaked info stating that the 4870 had 480 stream processors... I think we know how that turned out. Now I'm not saying that this is the case but AMD/ATI have been pretty coy in recent history, so who knows?

How much does the consume GTX295 @ load?

Seems like the figures here are a little exaggerated. I have no doubt ATI will figure out how to get the load TDP down with out a performance hit.
