This fall will not only see the introduction of the next G80 derivative at the high end, but Hara also stated that the company will start to product its first 65nm GPUs. Moving its GPU line from 90nm to 65nm will bring NVIDIA to process parity with AMD/ATI (not that the 65nm feature size appears to have given the R600 any advantage in performance or power dissipation), and it will give the company the flexibility to increase either their performance or their profit margins, depending on how AMD/ATI's next-generation part fares.
[NVidia] has to execute on its annual product refresh cycle, and it has to maintain performance leadership with its discrete GPU products across the mobile, desktop, and HPC segments that it's pursuing.
