NDA is Non-Disclosure Agreement, in other words, the people who know about the cards, press etc, aren't allowed to talk about it before NDA ends

30 watt idle TDP for the GTX 280
According to the slides it's true.
NV is gonna promote IDLE powerconsumption a lot... with just a small mention of LOAD powerconsumption.
But I guess most reviewsites will see through their PR plan.

Idle power consumption is one area where AMD was sticking it to them hard. If GTX280 idle power consumption is actually lower than G92 I would say that's a big deal. In terms of load performance/watt they actually had an advantage IIRC. Besides, the slide also shows that load power consumption is much higher so it's not like they're hiding the fact......

Holy crap... 147 instead of 80 for load!!!!!
It's one huge, hot chip indeed. And I don't care about the 20 watt advantage in idle if there's a 70 watt disadvantage in load.
Hmm, to think about it... If for each 9 hours my computer is on, I play 3d games for 2 hours and don't for 7 hours, it could balance it out. But someone who spends $650 on a graphics card would like to waste more of his life playing 3d games, naturally.

Compare it to 9800GX2 and 3870X2. Based on TR's numbers a 70 watt increase over 9800GTX still comes in under both of them. Not to mention 4870X2. Factor in the probability that it's faster than all three your performance/watt starts looking pretty good.

Yes, 2-times or more performance is a real disadvantage...

Common, it is nature law that GT200 will be the mainstream product with thinner manufacture node later in 2009.

I don't think they'll just shrink it to 40nm, they'll likely want to change the ALU-TEX ratio further as I said. One big problem on 40nm is how to have enough bandwidth yet not be pad/pin limited. Assuming that's not too much of a problem, I can easily imagine a line-up along those lines:
16C/512SP | 384-bit GDDR5 | 2.5TFlops+
8C/256SP | 384-bit GDDR3 | 1.25TFlops+
4C/128SP | 256-bit GDDR3 | 600GFlops+
2C/64SP | 128-bit GDDR3 | 300GFlops+
As for 55nm, we might see a 10C shrink of GT200, a 1C low-end discrete & IGP SKU and a 4 TMUs/8 SPs ultra-low-end IGP SKU.

Does "idle" mean only in a Hybrid Power mobo?, where the IGP is providing the display and GT200 is literally "turned off".
Jawed
Of course, these values definitly belong to just the card.
Hybrid Power = Zero Watts because the GPU is completely turned off. Since its basically been posted I will confirm the GTX200 cards consume less power than an 8800GTX, 9800GTX and 9800GX2 at idle by a significant margin.
