In just over two weeks, Nvidia will bring its Kepler architecture to the mid-range segment with the launch of both the GeForce GTX 660 and GTX 660 Ti graphics cards. Last weekend, several images surfaced depicting an EVGA Signature Edition of the GTX 660 Ti card. This GPU is expected to retail around $300 (£191).
Rumour has it that the GeForce GTX 660 Ti will be quite similar to the faster Kepler cards. The graphics card would even be based on the same GK104 325-A2 chip used in the GTX 670, albeit with a smaller 192-bit memory controller. The GDDR5 memory is reportedly still clocked at 6 GHz effectively. Other sources contradict this and claim this is only the case for the non-Ti version, which will feature 1.5 GB of GDDR5 memory. The main difference with the GTX 670 is that the amount of CUDA cores has been reduced from 1344 to 1152 units. Two GPU-Z screenshots were released to back this information.
The standard clock frequencies of the GPU have been elevated to 980 MHz, with a Boost speed of 1033 MHz. It's possible that EVGA has reserved these speeds for its Signature Edition card only though. It's expected that the adjustments compared to a GTX 670 have led to a TDP of about 140 to 150 watts. This would mean a single 6-pin PEG connector is sufficient to power the card.
The GeForce GT 660 Ti is expected to be released on the 16th of August.
