It was considered that the passage on 55 nm technical process will allow NVIDIA to reduce the prime cost of GT200 video chip production , but simultaneously this company needs to increase the frequency range, since now the 65 nm products lose to competing graphical solutions from
Today appeared information about the frequency characteristics of 55 nm video chip GT200b. Asociates with reference to its own sources report that the productivity of video chip will approach the 1200 gigaflops. Thus the frequencies Of GT200b will be equal to 648/1620 MHz. The frequency relationship of shader and gpu will be equal to 2,5. Let us recall that the 65 nm version GeForce GTX 280 works at the core frequencies 602/1296 MHz, and for it this relationship is equal to 2,15.
The core area will be decreased from 576 to 470 sq. mm. The increase in frequencies will hardly allow to significantly reduce the energy consumption level , we already observed similar picture upon transfer from GeForce 9800 GTX to GeForce 9800 GTX+ ( higher frequency and similar TDP ).
