information about the upcoming 512MB GeForce 8800 GTS based on the G92 core, just as with the 8800 GT, has made its way online; and it looks like we can expect these cards to launch just in time for the Christmas holidays, as the launch date appears to be December 3rd.
The cards should have 512MB of 256-bit GDDR3 memory clocked at 970 or 1940MHz effectively, and the core should be clocked at 650MHz. Finally, the Shader clocks should be hitting 1625MHz.
It will have 128 Shader processors, compared to 112 in the 8800 GT, and this is what really sets the 8800 GTS apart from the 8800 GT. We're not quite sure why Nvidia had to make a dual slot cooler for these cards, but apparently those extra few MHz are pushing the heat generated by the GPU too high for a single slot cooler.
The rumored retail price for these parts is US$299-349, although we have no way of verifying this.
