NVIDIA GeForce GTX 680 Review @ XbitLabs

Nvidia Strikes Back: GeForce GTX 680 2 GB on “Kepler” Graphics Architecture - X-bit labs
At last the patience of beautiful graphics fans has been rewarded: Nvidia has finally rolled out their response to AMD’s “Tahiti”. And today we are proud to present a new GK104 graphics processor on “Kepler” architecture and the first graphics card based on it.

One year and four months ago the GeForce GTX 580, Nvidia’s top-of-the-line single-processor graphics cards with the Fermi architecture, was released. That’s a very long time for the GPU market, so users have been eagerly awaiting the next Nvidia GPU with new Kepler architecture and 28nm tech process, analyzing every rumor and every piece of leaked-out data that could be gathered about it. To add more tension to the situation, Nvidia’s competitor AMD successfully launched its own top-end Radeon HD 7970 graphics card in late 2011 and it turned out to be the fastest single-GPU graphics card with enormous overclocking potential.

Well, the wait is over now. The GK104 processor and the Nvidia GeForce GTX 680 graphics card have finally arrived:

It is interesting that the GK104 is not positioned as a hi-end solution even though Nvidia claims the GeForce GTX 680 to be the fastest and highest-efficiency graphics card available right now. Nvidia is going to roll out faster solutions later this year, the 28nm GK104 and the GeForce GTX 680 being promoted as products that deliver highest performance per watt through the benefits of the thinner manufacturing process and Kepler architecture. Let’s check out the Kepler’s capabilities right now.
