The official GT300/Fermi Thread

[saaya]

It's really not that hard to believe they showed early silicon running a fairly simple (or at least short) demo at GDC. I'm not going to go through the arguments of why, because honestly that's a waste of time. But I think people here are being skeptical for the sake of being skeptical.

i totally agree, kinda like intels lrb demo...
but they didnt... they "supposedly" ran very taxing gpgpu apps and saw almost 2 digit fold increases in performance... for that to happen gt300 has to be fully functional, gpgpu uses all of the gpus resources, more than when you play a game most likely...

about being sceptic towards what nvidia claims... well it doesnt exactly help that they held up a fake card and lied to everybody out...

I have good experience with triple SLI 8800GTX overclocked and quad SLI on air. Even though I have no experience with more cards, I find it very difficult to believe CO2 is not enough. Liquid CO2 is very cheap. I believe it makes sense to refill a liquid CO2 tank every five days when we need to run 7 overclocked cards 24/7. We are not talking about extreme overclocking 7 cards for 24/7 folding here.

good experience as in heating your room?
as in flickering stuttering crashing game sessions? :P
and dont get me wrong, crossfire isnt any better either... and yes its useful if you need to get the fps up at high resolutions or in a demanding game... but you DONT want more than one gpu if you CAN play the game with one gpu at the same or almost same settings... thats at least my experience...

but what does that have to do with cooling 7 cards inside a case with liquid co2 from an external container that you refill every now and then... oh please... kinda like a watercooling loop but with liquid co2? thats a retarded idea... you can get the same effect by using chilled water, and guess what, thats what everybody in the industry does... thats how super computers are killed and thats how amd (ive seen the machine myself) and most likely intel and others as well cool very hot chips when running tests and thats how they cool them when doing thermal tests and power tests of some chips.

really, trust me... whoever came up with this 7 liquid liquid c02 cooled fermi cards running f@h thing there is a) mocking people desperate for gt300 infos b) desperate for gt300 himself and doesnt know what hes talking about

But would NVIDIA test with extreme cooling methods?

as far as i know they do
they had at least 2 cascades and used them to test their chips...
nvidia was the first chip maker to test their stuff on subzero and make sure they dont have coldbugs and scale properly... at the same time or even before ati, and long ago before amd...

its possible they use liquid co2 cooling, but unlikely...
and think about this, a cascade keeping a 200W+ gpu at -100C is going to need quite some juice, my guess is around 800W+ (fuggers tripple stage pulls up to 2000W iirc?), and its not a small cube either... now think about cooling 7 cards... and you get an idea of how ridiculous this is...
and while i can totally imagine nvidia testing gt300 running f@h on it, im sure they do it actually, its unlikely they do it with supercooling, and its completely ridiculous to think theyd do it with 7 cards in one rig... why would they do that? what for? how does it stress the card in any special way to have 7 in one rig? it actually stresses them less if anything cause there is a bigger lag from the cpu assigning them work and there is less pciE bandwidth per card to send and receive data... and if theyd want to test 7 cards to make sure it works fine, why would they supercool them? for what? so they can brag on some enthusiast forum about having a bigger e-penis... yeah right

enough with this 7 liquid co2 cooled fermi cards running f@h already! lets move on please :P
