No offense, but why would you ask that? Questions without answers, yeah? We're just playing the guessing game at this point about the GM204, GM200 is something else entirely. I'd imagine that it's an HTC first part so it would be quite high performing, and will require the 20nm node to be fully realized. Just my theory.
Anyway, this information isn't released to the public until release is basically imminent. Within 3-4 weeks of launch, and that's when you'll see NV or AMD do a press invite sorta thing. Asking these questions before that is a waste of time. Even then, these questions MAY NOT be answered until it hits the shelves.
I've not seen a GPU not adhere to that schedule, and if those facts come to light before any official announcement someone would probably involve someone losing a job due to leaking info and/or some websites would get blacklisted due to breaking NDA. Although now from what i've read elsewhere, websites stay in the dark just as long as consumers do pretty much. Due to NDA breaking. Aside from that there are guys close to the supply chain in China/TW who basically have leaked information for years with no repercussions. All GPUs roll off assembly lines over there, so, you'll see leaks come to light (as we already have for GM204). Whether they're all true or not is another story, but some of them are. I remember the leaks from chiphell (cantonese PC DIY website/magazine) for the 780 and 7970 were about 50% accurate, judging the final release silicon. But they won't have leaks for GM200, IMHO. GM200 is probably reserved for the 20nm node because you simply can't cram many more transistors above what the 780ti has on 28nm.
