GeForce GTX 660 Ti Also in 256-bit Version
Chinese website redquasar has leaked some interesting bit of information regarding a 256-bit version of GeForce GTX 660 Ti.

Apparently, there are two models of GTX 660 Ti, which differ in memory bus width and CUDA cores count. The one, which specifications were leaked few days ago, has 1344 CUDA cores and 192-bit interface. However, this model cannot beat the Radeon HD 7870, so NVIDIA came up with a new version with 256-bit instead, but also a castrated amount of cores – 1152.

The leaker says that this is a non-public version of the GTX 660 Ti, which is equipped with two 6-pin power connectors, while the 192-bit version would have only one. Card has a clocks of 980/1123/6000 MHz for base, boost and effective memory respectively. According to the source, card can reach a score of 2700 points in 3DMark11 Extreme Preset. That’s a score of Radeon HD 7970. What is more, it’s only 8% worse than GTX 670. Card can easily be overclocked to 1.2 GHz, just like other GK104 GPUs. Card is a dual-slot, short PCB model with two DVI’s, DP and a HDMI output.

NVIDIA is struggling whether to release a 192-bit version which will not beat HD 7870, or 256-bit model which will affect the sales of GTX 670. Author of the post is expected to provide a GPU-Z screen-shot, so we might verify this information.

In my opinion, this is actually the GTX 660 Ti graphics card, while a 192-bit model is a non-Ti. This would make sense, unless NVIDIA slightly decreases the clocks of Ti model, because it’s too close to GTX 670. We will see if those specs are true in a short while.

You can read the source page, it’s partially in English.

Head on here for more information about a non-Ti variant.
