There will be more Kepler soon. Nvidia builds hype by publishing a sparse picture of what appears to be the shell of a new graphics card. The caption is “it will come”. More than that is not revealed by the update.
According to SweClocker’s sources, this is nothing less than the Geforce GTX 690, a pure enthusiast model with dual GK104. It is the same graphics processor used for the GTX 680 flagship.
Speculation is that the new graphics card will be released in late April or early May. A recurring date is April 30, but this is still far from confirmed.
