The GK104 GPU will be priced at $299 (about 230 EUR)  as sources now claim, the sources being various Nvidia AIB partners.

From what we can tell this is only a preliminary price so Nvidia could change it a slightly until the final GK104 parts are shipped depending on chip volume and yields.

GK104 indicates the mid-range product (expected to perorm at current high-end level). Last week a Chinese publication claimed that the upcoming GK104 core would feature a 256-bit wide memory bus, which would be connected to 2GB of video buffer. While the shader count and operating clocks were not provided, the Thermal Design Power (TDP) of GK1104 cards seems to be set at 225W, which is quite close to the GTX 570 (219W).

Nvidia’s Kepler GPUs will also be manufactured using TSMC's high-K metal gate (HKMG) 28nm fabrication process.

The release date of the Kepler graphics processors is not yet known, but an Nvidia official suggested during CES 2012 that the company’s first such parts would be launched in late Q2 or early Q3 2012. However with so many rumors and gossip, typically a launch is pending closer then we think.
