We were originally told by one of our sources at an AIB that Nvidia's GeForce 9800GT graphics card would be no more than a 8800GT with a new label - same clock speeds, memory and so on.
VR-Zone is now speculating that the 9800GT will actually be the first desktop graphics card from Nvidia to be based on a 55nm manufacturing process, down from the 65nm on the previous generation. Naturally, Nvidia are said to be doing this to reduce costs but of course it will also mean a reduction in temperatures.
While the 9800GT may well carry the same default reference clock speeds and specifications as the 8800GT, if this news turns out to be accurate, there is a good chance you will see a flood of super factory overclocked cards based on the G92b 9800GT core.
Only time will tell.
