Nvidia is reportedly set to finally expand its Kepler-based GPU lineup beyond the current high end offerings (and a lone $99 GeForce GT 640).

According to Sweclockers, the GeForce GTX 660 Ti will arrive at some point between August 13th and 19th with an MSRP of $299, making it a direct competitor to AMD's Radeon HD 7870 GHz Edition which received a price cut just last week.

Similar to the GTX 670, the GTX 660 Ti would be based on the GK104 core architecture with 7 SMX units enabled for a total of 1344 CUDA cores. Their specs are expected to differ when it comes to memory, however.

While the GeForce GTX 670 has either 2GB or 4GB of GDDR5 memory on a 256-bit interface, the GTX 660 Ti will reportedly have 1.5GB or 3GB of GDDR5 memory with a 192-bit interface. Clock speeds should be lower as well but no specific numbers have been quoted.

Images of a purported GeForce GTX 660 leaked in May so it's possible that a further scaled down version of the card without the Ti moniker might also be in the works and ready to launch in August. The card would presumably target the all-important ~$250 price point to counter AMD's Radeon HD 7850.
