GT200(b), GT300 SKUs Make for Early Sighting
Second to be listed, which looks rather surprising, is that of a GeForce GTX 350, based on the GT300 graphics processor. Again, whatever little specifications listed, show that the card is based on the 55nm silicon fab. process and holds 2 GB of GDDR5 memory across a 512-bit wide memory bus. It is mentioned that the product could be available any time in Q4 2008. Is NVIDIA gearing up for X'mas?
