Charlie Demerjian over at SemiAccurate has revealed the die size of NVIDIA's upcoming Kepler GK104 chip. According to him, the GK104 chip would measure18-19mm x 18-19mm ranging to324-361 mm2 .

This means that the GK-104 chip would actually be smaller than the Tahiti Core chip which measures 365mm2, Various rumors also suggest that the GPU based on the same GK-104 chip would perform similar to the HD7970 which means powerefficiencywould also be similar to the Tahiti consuming a tad bit more power than Fermi. A previous article from us suggests that the TDP would be somewhere around 225W in the GK-104 chip on a 28nm design.

An Alleged price around the $299 mark means that the same GK-104 graphic card would completely dominate the Performance segment market if the performance holds up as is rumored. The release date is expected sometime around March-April 2012 andyieldswon't be much of an issue on Nvidia's side. Expect more info as the launch date nears.
