Nvidia shrinks G80 and names it G90
Reports show that Nvidia are working closely with TSMC to make this happen.
Those same sources say Nvidia needs a more cost-efficient way of producing G9x high-end chip based on the G80 marchitecture. Chances are that Nvidia is working with TSMC to produce the chips on a 65 nanometre process. The resultant shrunken chips would work with much higher frequencies, and powered with GDDR4. But we still have to confirm these details.
