On August 16 it is planned to release one of the first mainstream cards Nvidia family Kepler — GeForce GTX 660 Ti. Different sources are still disagree considering its characteristics. It is known that it will be based on the graphic chip GK104 and have a more modest power system than the GTX 670. Crippled in its capability GPU GK104 will form the basis for GeForce GTX 660 and, probably, GTX 650 Ti. Boards of mainstream class and below will use the processor GK107.
Actually, GK107 is already present in the market as part of the line of video cards GeForce GT 640, but it limits the potential by slower memory DDR3. Release of modifications GT 640 with GDDR5 chips on board, according to foreign analytics is just a matter of time.
It is believed that the GeForce GT 640 GDDR5 will receive commercial name GeForce GTX 650. This assumption is not without logic, because it will be easier for Nvidia to sell large quantities of video cards (notice how long the Santa Clara did not use the prefix SE, GS and LE?). GeForce GTX 650 will adopt a 384 shader units, the memory bus 128 bits and at least 1 GB of onboard memory type GDDR5. The announcement of models will take place on September 17 — then all specifications will be available to judge.
