Re: No GTX680 until Q2 2012
Expreview show off GK104 core die.
It slight bigger than G92 core die.
I googled G92-421-B1, it wasn't G92 but actually it is 55nm G92b core on GeForce GTS 250 cards so it slight bigger than 231mm2. It is incredible much smaller than Radeon HD 7970's 365mm2.
I think poor AMD will have a very hard time compete with Nvidia this year after Bulldozer horrible performance and Llano yield disaster in 2011.
