During a keynote presentation at GeForce LAN 2012 being held in Shanghai, NVIDIA's CEO Jen-Hsun Huang unveiled what many of us have been theorizing would be coming soon; the dual-GPU variant of the Kepler architecture, the GeForce GTX 690 graphics card.
Though reviews aren't going to be released yet, Huang unveiled pretty much all of the information we need to figure it out. With the full specifications listed as well as details about the stunning new design of the card and cooler, the GTX 690 is without a doubt going to be the fastest graphics card on the market when it goes on sale next month.
The GeForce GTX 690 4GB card is based on a pair of GK104 chips, each sporting 1536 CUDA cores, basically identical to the ones used in the GeForce GTX 680 2GB cards released in March. The base clock speed of these parts is slightly lower at 915 MHz but the "typical" Boost clock is set as high as 1019 MHz, pushing it pretty close to the performance of the single GPU solutions. With a total of 3072 processing cores, the GTX 690 will have insane amounts of compute horsepower.
Each GPU will have access to 2GB of independent frame buffer still running at 6 Gbps, for a grand total of 4GB on the card.
Sitting between the two GPUs will be a PCI Express 3.0 capable bridge chip from PLX supporting full x16 lanes to each GPU and a full x16 back to the host system.
In terms of power requirements, the GTX 690 will use a pair of 8-pin connectors and will have a TDP of 300 watts - actually not that high consider the TDP of the GTX 680 is 195 watts on its own. It is obvious that NVIDIA is going to be pulling the very best chips for this card, those that can run at clock speeds over 1 GHz with minimal leakage.

More information has surfaced about NVIDIA’s GeForce GTX 690 video card. While other tidbits came to light, perhaps most interesting is the expected May release.
NVIDIA has suffered from quite a few leaks near their launch of the GeForce GTX 680 GPU and its associated cards. Benchmarks were accidentally published early and product pages were mistakenly posted premature. The hot streak continues.
It may be time to just reset fate and skip to the GTX 700-series. I mean they will eventually be rebranded 700-something anyway.
I kid, I kid.
Not many specifications were leaked, although there is not much left that cannot already be assumed about the card due to the similarities with its sister part.
The reference model GTX 690 will require two 8-pin power connectors and output via three DVI ports as well as a mini DisplayPort. The already released GTX 680, by contrast, requires two 6-pin connectors and outputs by two DVI, an HDMI, and a full size DisplayPort.
The new card will require more power for its dual GK104 GPUs as the larger power connectors would suggest. While the GTX 680 is happy with 550W of total system power, the GTX 690 would like a system power supply of at least 650W. Since the 680 is expected to draw a maximum of 195W, an extra 100W would put estimates for the 690 power draw at somewhere around 295W.
Unfortunately estimates based on rated total system power are very inaccurate as power supply requirements are often raised to the nearest 50W. Really, the 690 could be anywhere between 245W and 295W and even those figures are just estimates.
Still, it looks as though my 750W power supply will survive past May when the leak claims that the GTX 690 is expected to arrive. Yay! May!
