NVIDIA is cooking up another G92 based graphics card according to VR Zone. The site writes NVDIA will shrink the G92 from 65nm to 55nm in the second quarter of this year to compete against the AMD RV770 GPU.
DigiTimes today reported that RV770 will come along by end Q2 which is about the same timeframe as the 55nm G92. Most probably, you will see RV770 based mobile parts first as notebook makers have already received RV770 samples for testing.
Right now, we are able to confirm some 55nm G92 mobile parts coming up to pit against the 55nm RV770. Most likely, there are 55nm G92 for desktop parts too as Nvidia in desperate needs to lower cost and improve yield in the next couple of months ahead to stay in competition. In any case the 55nm G92 even with higher clocks can't match up against RV770, Nvidia will have to push ahead the schedule of next generation GT200.
