GeForce GTX 660 Ti Specifications and Launch Date Released
 

According to the latest set of specifications scored by SweClockers, NVIDIA's upcoming performance-segment GPU, the GeForce GTX 660 Ti, is not much different from the GTX 670. The GTX 660 Ti is based on the 28 nm GK104 GPU, with 1,344 CUDA cores enabled - the same number as that on the GTX 670. What's more, the clock speeds don't differ between the two, either - 915 MHz core, 980 MHz GPU Boost, and 6.00 GHz GDDR5-effective memory.

The memory amount stays 2 GB, as well. It's just that the memory bus width is reduced from 256-bit to 192-bit, resulting in 25% lower memory bandwidth. The 2 GB of memory is spread across the 192-bit memory bus, probably with four chips using 32-bit wide paths each, with four other chips sharing two 32-bit wide paths. NVIDIA is known for pulling off such memory configurations, like it did with the GeForce GTX 550 Ti.
