Well Newegg is listing the cards again, and they are all "Out of Stock".....
so check out the OpenCL bench numbers for dual / single precision.

Crap. I don't know what else to say. Is NVIDIA this pathetic? Are they saying they purposely detuned the card so it sucks for crunching? This probably to sell their high end Tesla cards or whatever instead, right?
Very, very disappointed with this. What's next to evaluate? Any other benchmarks we need to consider, etc to make our decisions?
Well, this changes things a bit. The 7970 clearly outperforms the GTX680 for our purposes. Perhaps you should wait till we start to see these cards on DiRT, PG and others.
Yeah, I agree with you there. The waiting game is on now. I will use this time to start getting it together for whichever GPU is better.
Maybe there is something to JPM's post about the GK110 chip that NVIDIA was supposed to come out with for the higher end? Wonder when all this will finally be out in the open and we can see our real options...
Unfortunately that review is tainted. The AMD 6990 is a Dual GPU unit. Apples to Oranges. Stupid, very stupid. Or at least the review should have included the 6970. And somehow the reviews conclusion says the GTX-680 is a good card. How? It's intentionally crippled compute performance. At idle, it sucks up the same amount of power as the 7970. It cannot beat it's predecessor on several benchmarks. Plus, it's new transcoder is limited to H.264 output! So for all that, they want more money than a 580???
Sorry, but from my point of view nVidia it the biggest tech scam artist on the planet. All they have done is set it up so that Joe consumer is footing the bill for all their R&D, slanted reviews and over priced ad campaigns while reaping in the motherload from their commercial Fermi products. And the really sad news? Joe consumer is eating it up like a nine year old given free access to the candy store.......
Well at least the 680 will put pressure on the rest of the GPU market, nVidia and AMD alike.
Nvidia has always done that, starting with the 400 series, however then they only crippled double precision by 1/8th. This 1/24th crap is pretty bad
However "We asked NVIDIA about this and they said that a folding update is in the works"
As it stands now, imagine Dirt on the 680. Nearly double what a 580 can do? Yes please.
EDIT: but yeah, if you work on double precision projects, always go with AMD. Nvidia will always intentionally screw you over there. I remember back on the old forums i ranted about this for days. Even ranted on Nvidia's forums and a few team members joined in. Clearly it hasn't changed things. But now, just because i can, i will write an article about it for LegitReviews directly aimed at letting us folders know what's really going on. I just need a little more info first...
Also, Nvidia's GPUs have always been better at double precision than AMD's. No one knows that because they keep it crippled, but uncrippled, Nvidia can do SP : DP @ 2:1, meaning the 680 *could have* a DP rating of 1545 GFLOPS (which is about 40% faster than AMD's 6990!!!!!). That's what we're really missing out on.

Making it slower than their *own* previous generation product is insane. Suicidal even.
Which projects require double precision again?
