The first 2 models from the GeForce 9900 series will be 9900 GTX and 9900 GTS instead of 9900 GT we reported earlier. It seems Nvidia has decided to launch them as early as July to counter RV770 and steal the performance crown away. Nvidia has earlier confirmed GT200 existence and revealed that the GPU has about 1B transistors. Our sources are suggesting a 512-bit memory interface with GDDR3 memories for GeForce 9900 GTX using P651 PCB and a 448-bit memory interface for the GeForce 9900 GTS.
