G92 is now a high-end chip, says Inquirer
This baby sports some serious shading power, but more important is the fact that the memory installed on board is now GDDR4. 768MB of GDDR4, to be more precise. The amount of memory discards rumours of 256-bit bus, since it is obvious that Nvidia will keep 384-bit memory controller for the high-end series of products… The bandwidth has now jumped over the 105 GB/s barrier, and it remains to be seen what will be the final clock of the memory ? our estimate is between 1.0 and 1.2 GHz, or 2.0-2.4 GHz, but final clocks are far, far from being decided.
