According to PC Online, this cooler will fit onto GT200-based "GeForce 9900 GTX" products that will feature 240 stream processors, 32 raster units, 1GB of GDDR3 memory, and 512-bit memory interfaces. Supposedly, the first GT200 chips will be built on a 65nm process, so the cards will have power envelopes as high as 240W. 55nm GT200 GPUs may follow later on, however.
Rumour has it that the GT200 GPU will be available next month for $499.
