According to our associate , GT200 will be the doubled core g92b in one chip with 300-350 sq. mm area. This chip will count more than 900 million transistors. It will be produced by TSMC on the 55- nm standards.
This GPU will have 192 stream processors , united in 8 units, 32 ROP.
The memory interface is planned with 512- bit, memory GDDR3.
Frequencies probably will be determined only a pair of weeks before the release of products .
As a whole, it appears as the two-processor geForce 9800 GX2 in single-processor accelerator. Associate report that the performance Of geForce 9900 GTX will be sufficient for comfortable game play in Crysis with very high setting with 4- AA and resolution 2560 x 1600. But it is difficulty to believe such data .
