gtx680 GeForce GTX680 marketing video leaks

In what appears to be the real deal, an Nvidia marketing video has leaked just ahead of the GeForce GTX680 launch. The video details some of the new features we can expect to see, as well as it confirms the earlier leaks of what was said to be GTX680 cards.

Nvidia is making some bold claims about the GTX680 in the video and although the card in question might very well feature the fastest GPU out there when it launches, but we're really curious about the power consumption and noise level and here Nvidia claims that we're looking at a really power efficient chip that shouldn't be as noisy as previous generations.

First up of the new features is GPU boost, something similar to Intel's Turbo mode, but it appears to be far more limited. If you look at the screenshot below from the video, it's adjusting the clock speeds on the fly, but he gains are at least according to that particular scenario in the 10's of MHz rather than the 100's. GPU boost only works in games that aren't very “power hungry” in terms of actual electricity which means that the GPU heats up less and as such the additional thermal envelope allows for small overclocks.

 Next up we have FXAA which is a new type of anti-aliasing which Nvidia claims doesn't take a “performance hit” like traditional anti-aliasing technologies. This will be interesting to see in action, especially if it's as good as Nvidia claims.

For PhysX Nvidia has added some new features such as dynamic fracturing of objects which means that an object will break differently every time it breaks, unlike in the past when an object had limited ways into which it could break. Nvidia has also managed to improve hair effects, although we'll have to wait and see if this will actually end up in a game in the future, as otherwise it's mostly a pointless addition.

Finally Nvidia is making a big deal out of 3D Vision Surround with up to three displays, but considering the additional cost of displays and active shutter glasses we have a feeling this isn't going to be a major selling point as far as most consumers are concerned. The GTX680 can also handle four displays simultaneously, although Nvidia still has at least one more to go before they catch up with AMD when it comes to multi display support.
