Video cards based on GK210 support more advanced version of CUDA. For example, last spring inconspicuous newcomer named GK208 offers CUDA support not less than 3.5, while its predecessors are satisfied with version 3.0.
The first mention of GK210 send us back to April this year - examples of this GPU crossed the border in India, leaving a trail in the customs database. The letter "K" in the name GK210 indicates that the product has the architecture of Kepler.
Logically, we can conclude that GK210 - a successor GK110, focused on the use of accelerators Tesla, whose performance in this particular application, increased slightly due to the support of a new version of CUDA and other related improvements. In the end, computational accelerators provide a decent level of profitability, and for them NVIDIA is ready to create specialized processors. Even if the GK210 and would have ended up in the video game, it is unlikely it would have brought changes in productivity.
