Gainward company released two versions of the GeForce GTX 660 Tі: one copies the entire design and characteristics of the reference sample, and the second equipped with a proprietary cooling system, Phantom and operates at higher frequencies.
With the cooling system we are familiar with Phantom since the announcement of graphics card NVIDIA GeForce GTX 680. The second revision of the cooler Phantom, which is equipped with a new product, includes a massive heat sink that covers the whole area of the PCB, two 80-mm fans and five copper heat pipes with a diameter of 8 mm.

The power system is organized on a "4 +2" phase. In order to achieve a stable voltage supply voltage regulators are used DrMOS.
Basic graphics core frequency of 1006 MHz, high - 1084 MHz. Memory that is 2 GB, works with the effective frequency 6108 MHz. We recall the formula frequency of the reference sample is given by 915 MHz (980 MHz) / 1502 MHz (6000 MHz) ((kernel mode (Boost) / memory (effective rate)).
The package includes software Expertool II, which will help users to overclock. According to the manufacturer, the superiority card Gainward GeForce GTX 660 Tі Phantom of the graphics card NVIDIA GeForce GTX 570 and AMD Radeon HD 7950 in 3DMark 2011 benchmark Xscore of 46 and 18.4 percent respectively.
