NVIDIA GeForce GTX 660 Ti Final Specification
NVIDIA’s GeForce GTX 660 Ti has a really impressive numbers. According to SweClockers, GTX 660 Ti and GTX 670 will only differ in the memory interface width.

SweClockers claim that they came across the final specs of upcoming mid-range GTX 660 Ti, card that is said to offer slightly worse performance than GTX 670. Well, numbers are quite clear, the only difference between these two is the memory bus width — with 192-bit for GTX 660 Ti and 256-bit for GTX 670. Narrowed memory interface will decrease both the memory bandwidth and power consumption. The GTX 660 Ti will have a TDP of 150W, with a requirement of two 6-pin power connectors. Memory bandwidth will drop to 144.19 GB/s (that’s 48 GB/s less than GTX 670). Furthermore the GTX 660 Ti will hold the same memory capacity of 2GB (GDDR5). When it comes to the frequencies of all clocks — these are the same for both cards (but this might change before launch).

GeForce GTX 660 Ti will almost certainly use Kepler GK104 GPU with the same amount of SMX clusters holding 1344 CUDA cores. This would also indicate that it will have 112 TMUs and 32 ROPs. This mid-range card will have a very short PCB, which is almost identical to GTS 450’s.

Since there is no update regarding GTX 660 non-Ti variant we won’t speculate about it. Although if OBR is correct, then the non-Ti model will offer a performance of GTX 580, while 660 Ti (when overclocked) a performance of GTX 670.

GeForce GTX 660 Ti will launch on August 16th. According to the source, the availability of the graphics card will be relatively good, indicating that the GTX 660 Ti will hit stores as early as the launch day. The price is still unknown but the latest rumors say that it will cost around $320-$330.
