I know there's no standard for measuring TDP, but that ought to qualify as false advertisement. TDP is supposed to be a maximum value that the product should almost never reach in normal usage, but it looks like the 480 is a good deal past that under normal and way past that in furmark.
Lol, I think I remember Toyota or someone else saying what Charlie reported as Fermi's TDP wasn't bad since real numbers would be lower, but this seems to be the exact opposite scenario.
The problem is as you stated that there is no standard for measuring TDP. Just like how there are LCD monitors that make crazy response time claims but will actually lose in a head to head with a supposedly "slower" LCD. nVidia can make all sorts of crazy claims as long as it's true, probably with qualifiers in the fineprint.
Here's a case in point with AMD and Intel as examples. While the link is to CPU's it can serve just as well for GPU's in that each company can use a different metric by which they measure TDP. In this case with the GTX 480, nVidia is clearly listing something that is lower than the max power draw. And as shown in several reviews, when playing a demanding game such as Crysis, TDP goes well over the 250W listed. Now, technically they are not lying since there is no standard way to report TDP. They can use different metrics for each card in their lineup if they wanted to. Deceptive? For sure. But it's legal. At least for now.
