We know from older reports that NVIDIA is working on GeForce GTX 690, a dual-GPU graphics card based on the 28 nm GK104 silicon, we also know that its launch will be strategically timed to follow that of AMD Radeon HD 7990. Expreview scored a few juicy details about this card. To begin with, it is reported that GeForce GTX 690 will draw power from two 8-pin PCIe power connectors.

The GeForce GTX 690 will use a PCI-Express 3.0-compliant bridge chip. Its display outputs will include three DVI and one DisplayPort. PSU with at least 650W capacity will be made a system requirement. The entire feature-set of GeForce GTX 680 will be carried over. The exact specifications, core configuration, and memory amount, remain at large.

If you have the money for a GTX690, paying for a good quality 650-750W PSU won't be a problem

Pretty much. Doubt somebody is going to try and toss a $600-800 GPU into an eMachine with some 350w TokyoDynaPowerBananaTec PSU in it. If you're paying for top of the line hardware, odds are you've got at least a 750w PSU.

Really?

Remember that they have to allow for awful PSUs and power-hungry CPUs. Would you run a GTX590 in a high-end rig with a cheap 650W PSU?

I'm a huge fan of dual GPU cards. They are usually cheaper than two dedicated cards. I've been using a 4870X2 for years and never had a problem with it. I might buy a 590 or 6990. Waiting for reviews:).

Even if it takes 2x8pin, the total power draw will still be less than 400w. I have no problem running it on a 650w, especially with a HX650.

Actually, 650w (allowing for a sub 80% efficiency unit) is pretty damn reasonable for enthusiast level SLI (or CFX)

GTX 680 SLI requirement: 750 watt
HD 7970 CFX requirement: 750 watt
HD 6990 requirement : 750 watt
GTX 590 requirement : 700 watt

And as others have mentioned, if you can't be bothered investing in a quality component that should be the heart and cornerstone of the system (i.e. the PSU) maybe you shouldn't be looking at $700+ worth of graphics. :rolleyes:

Dual GPU has great theoretical performance, but in reality most of its potential is lost with poor engine support, weak driver support and issues with micro stutter. At the end of the day the only viable option for multi GPU is if you buy the cards with the fastest gpu, and even then the benefit is marginal, and far less than the 2x FPS some games claim.

I recommend checking out overclockers.ru SLI/CF benchmarks that take into account frametimes. Might come as a shock to some.

The main reason that im not is stuff like micro-stuttering and driver issues, not a fan of driver issues. Your favorite game does not support multi-GPU? no problem, just disconnect one card and things will work great. Have a dual-GPU card? some of the times you will be in big troubles even though only one GPU is being used.

Well if its anything like the two 680's I am running now any one will be happy with the performance and sound. I really like how quiet these cards are, but sadly I can see the two 690's in SLI not gaining much performance like the 590's.

So you'd run a GTX590, say an i7-980x @4.4GHZ, perhaps 4 hard drives, half a dozen fans and a couple of other minor expansion cards on a generic 650W (since when is the HX650 a "cheap 650W"?)? It might work, but I think you'd be pushing your luck.

Which is why that the Company's Driver performance is key for dual GPU - nvidia tends to do better here.

Single GPU is where it is at though.

I am wondering if both vendors will have enough chips to sufficiently supply the market. AMD's 7970 seem to be plentiful, so they may not have a supply issue. Nvidia's 680 on the other hand seems to be OOS or on back-order every time I check (multiple sites).

I think Nvidia will release the 690 in very limited quantities to blunt the release of 7990.

More than this thing considering its already starting out with a 20W for each GPU disadvantage. So OUCH for the 7990 more so than this thing. ;)

So you'd run a GTX590, say an i7-980x @4.4GHZ, perhaps 4 hard drives, half a dozen fans and a couple of other minor expansion cards on a generic 650W (since when is the HX650 a "cheap 650W"?)? It might work, but I think you'd be pushing your luck.

(If you think I'm putting words in your mouth, then, in the kindest possible way, read more carefully the post of mine that you originally responded to.)
That is a valid point, but I basing my calculations on a 2500k with light overclock, which takes 150w on normal loads. Yes, me taking the HX650w is not really representative of the market, but I am still more than willing to take a trusted 650w to power the GTX590. After all, as long as you don't go crazy and load furmark and LinX at the same time and keep the overclock at good perf/watt a decent 650w can easily power most rigs of today. GTX590 peaks at 350w in gaming tests, giving you more than enough juice for an overclocked CPU. If you are planning to get the 980x at 4.4Ghz, then you should have done your research better and get a more beefy PSU ;)

Don't even care about this card. I WANT GK110 NOW :mad:
You should mean GK100 (large single Kepler GPU). You just have to wait to the end of this year. It's name may be 790. This dual GK104 IS GK110. ;)
