Few details about NVIDIA's G92 have leaked onto the Internet yet but The Inq managed to get their hands on some details:
When it comes to performance, even if this chip was just a shrunk-down G80, the clock would give significant benefits in performance thanks to increased clock of the GPU itself. Luckily, for future owners, that is not the case - Nvidia reworked quite a lot of things from the original architecture to make this thing work faster.
We managed to learn that GPU clock has surpassed 800 MHz and that company plans to deliver the boards depending on yields they will get. So far, launch clock could be anywhere between 800 and 850 MHz, with 812/3, 824/5 and 830/5 being usual suspects. This time around, there is no hurry and Nvidia knows they can afford the launch of GTS/GTX and wait for R680 to show up and launch the Ultra version as a counter attack.
There is quite a lot Nvidia has to support with the G92 series of chips, and what yours truly wonders the most is will the G92 support just Open GL 3 (Long Peak), or will the chip support Mount Evans as well (upgrade of Long's Peak). Of course, DirectX 10.1 is also a moot point at this time, and worst case scenario would be support for DX10.0+, but somehow we don't feel that source was right on target.
