GT212 is the follow-up to 55nm GT200b (GeForce GTX 285) which is currently rolling into production.  It entails a die shrink to a smaller fabrication process and interestingly enough, a decrease in memory interface width. But more on that in a minute.

See, the memory interface of GT212 will decrease from 512-bit on GT200 to 256-bit, however, Nvidia will plant Hynix 7Gbps GDDR5 on the GT212.  One of the most interesting facts is a healthy increase in the Shader domain of the GPU. The shader processor count of GT212 will go from 240 in GT200 to 384, and the number of texture mapping units will increase from 80 to 96.

Due to all the changes the number of transistors could jump towards 1.8 billion.  Interesting stuff.
