If it gets GTX 680 SLI performance, $799 sounds good to me.

According to current rumors, the hd7990 will be using two fully operational Tahiti GPU's clocked at 850mhz (vs. 925 for the hd7970). Since Nvidia has the upper hand on power draw this time around, they might be able to keep a pair of GK104's at full speed (1006mhz) in a dual card setup. If that happens, Nvidia will easily win the dual-gpu fight.

What I find more interesting is the GeForce GTX 685 (GK110). I'll take three of those.

Slightly less power potential that 680 SLI.

225x2= 450 total TDP for 680 SLI

375 total TDP for this card if the 8+8 is correct.

Currently stock 680's in SLI are rated for 390 watts, so this would be downclocked probably I would guess.

Should be ready right close to when Santa is coming hopefully.

The 590 was forced below 580sli performance because of power and thermals, so it did not eat into 580 sales. They can easily put 680sli on a single card. If they neuteur this card and use 670 cores it could lose out to a 7990 which they do not want I assume.

Think they are going to be forced to kill dual 680 sales with this card to keep a lead on the 7990.

True that - dual card match is a TDP battle,

yet Nvidia managed pretty much a tie - with the freaking Fermi against the Cayman(!)
(Later converted into a perfromance win via Cata crew dropping the ball :rolleyes:)

So move along ppl. Nothing to see here. Nvidia wins this one handily.

Nope.

You're forgetting some simple facts: AMD has better multi-GPU scaling than NVIDIA. They also lose less performance at ultra high resolutions like 2560x1600 and 5760x1200.

The GTX 690 will win, but only by around 5-10%. Same thing as the HD 7970 vs GTX 680 will happen.

There's no need for that, both camps typically cherry pick the gpus for their high end dual gpu cards. Plus, the total power draw for a single card with 2 gpus will be much lower than the total power draw for 2 separate cards with 1 gpu each. They might even end up close to 300w.

Huh?

I'm talking about max TDP possible with either setup.

As per overclocking potential, since TDP is directly related to Kepler clock potential.

There would be a hard limit currently of 375 watts overclocked for the dual gpu card, vs 450 total possible for reference 680 sli.

You always pop into threads with these absolute claims. Like when you were claiming gtx680 would be gtx560sli in performance (it ended up being faster), when you spouting Tahiti's specs months before it's release, and now this. It's one thing to make a prediction, but it's another to assert your opinions as pure fact, ESPECIALLY when you are basing your "factoid predictions" on either unconfirmed information (like Tahiti's specs or gtx680's probable performance) OR, in this case, on outdated information.

I'm not going to get into an argument with you, because it's pointless on several levels. But based on hardocp's gtx680 SLI review and cross referencing that article with their original gxt680 review Mass Effect 3, Batman AC, and Deus Ex scaled better with SLI than crossfire. BF3 scaled better with crossfire. The other game, Skyrim, didn't matter beause Nvidia's lead is so high it would take 150% scaling in crossfire to catch SLI. So, in other words, based on hardocp's demanding in-game settings they found that SLI scaled as well as or better than crossfire. You based your "fact prediction" on information of past products and are entirely wrong in regards to how the dual GK104 card will end up vs. the dual Tahiti card.

Not that I care which card ends up faster, I have no interest at all in dual card setups.

BF3 scaled better with crossfire, and Nvidia's lead in Skyrim is so high that I didn't bother to calculate who scaled better.

I'm telling you since I'm unbiased.

NVIDIA has the crown for the fastest single and dual-GPU cards, but in terms of multi-GPU scaling and performance loss at ultra high resolutions they're worse. Kepler doesn't change this.

Difference in performance between the GTX 690 and HD 7990 will be very similar to the one between GTX 680 and HD 7970. NVIDIA gets an advantage for superior power consumption, and AMD gets an advantage for superior multi-GPU scaling and lower performance losses at ultra high resolutions.

Seems simple enough.

But what about price? o_O

Edit: Oh and one seems to be more SFF friendly :p

I more expect 2 670 GPU's than I do 680's. Look at the disaster that was the 590. I wouldn't release any 300+ watt video cards. If people want 2 GPU's they should get SLI and not these. I owned the 9800 GX2 and the 295 and was much happier when I switched to two discrete cards.

nVidia's power numbers are good, but the PCI-E spec calls for a max of 300W for a single card. Although some cards have broken this physical specification (6990 and 590). But going to 400W is basically throwing the specification out the Window. My thinking is the 690 will also be clocked down from their single card speeds. Just like the 6990 and the 590 were, and looks like the 7990 will be.

375, you're forgetting the 75 it draws from the PCIe lane... Unless dual cards no longer pull power from the PCIe lane.. If so disregard.

Is 1006Mhz the full speed? Mine turbo boosts up to 1100Mhz..

I was going off what Ryan states here:

http://www.anandtech.com/show/4209/amds-radeon-hd-6990-the-new-single-card-king/5

At present time the specification and its addendums specify normal (75W), 150W, 225W, and 300W PCIe card operation. In the case of 300W cards in particular this is achieved through 75W from the PCIe slot, 75W from a 6pin PCIe power connector, and 150W from an 8pin PCIe power connector.

Looks like a badcase of PS where they used the GTX590 board shot and then chopped in the GK104 die and blurred the whole thing..

I'm seeing 2x8 pins, or am I seeing things? :(

They look like two 8 plins connectors to me as well, which means 375W. I am just saying the PCI-E spec only allows for 300W total. Or at least this is what I see everywhere I look, including the PCISIG website.

I am not saying the 2x8 power wont supply 375W, only that it surpases the PCISIG High Power Card Electromechanical Specification.
