NVIDIA GeForce GTX 660 Ti Launch Date And Specifications Revealed
NVIDIA’s upcoming mid-range card, the 28 nm Kepler GK104-based GeForce GTX 660 Ti, will indeed be released on 16 August as initially suspected. Weighing in at 1,344 CUDA cores and with base clocks of 915 MHz for the GPU core with boost up to 980 MHz and 1,500 MHz (6.00 GHz effective) for the 2 GB of GDDR5 memory, the card will have very similar specs to the higher-end GTX 670. So, where is the difference?
The memory bus width has been cut down from 256-bit on the GTX 670 to 192-bit on the GTX 660 Ti, which results in 25 % lower bandwidth between it and the core. In order to do this, NVIDIA will use a memory configuration similar to that found on last generation’s GTX 550 Ti and GTX 560 SE with half of the chips on a dedicated 32-bit path each and the other half with two chips sharing each 32-bit path. To explain this, four 2-Gbit chips will each have their own 32-bit bus (amounting to 128-bits), while the remaining four will be paired up on two 32-bit buses (bringing the total up to 192-bits).
