GTX 660 video card: characteristics, comparison with competitors and reviews

Both now and a couple of years ago, NVIDIA tried to take over the entire graphics market. The company creates a huge number of models that are included in a particular series. Today we have to remember the GeForce 600 line. Almost 5 years ago, it presented a lot of new and interesting things. One of the available models in this series was the GTX 660. Its characteristics should have been identical to its predecessor, the GTX 660 Ti, but that was not the case.

Complicated story

To understand the emergence of this model, it is worth delving into the history of production. Almost the entire line of GeForce 600 worked under the leadership of the GPU GK104. This processor was attributed to the second category, besides at that time there was no new one hundredth version on the market.gtx 660 specifications

As a result, the release of the GTX 660 Ti, whose characteristics were not far from the older models, became a lightweight variation of the same GTX 670. Therefore, when the company introduced the world to a model without an index, no dramatic changes should be expected. But it all happened very differently. It was decided to develop a GTX 660 based on the GK106.

A heart

So, the new processor for the GTX 660 got quite good specifications. For him, the main feature was the presence of asymmetry: one of the graphic clusters received not two streaming multiprocessors, but one. Also, the chip has 960 CUDA cores, inside there are 80 texture elements and 24 ROP. In comparison with the GK104, the number of computing units has significantly decreased. In the light of such events, it was not surprising to find a huge difference between the new chip and its younger version, the GK107. The rest of the cache set 384 KB, the memory bus turned out to be 192-bit.


The appearance of the GTX 660 was not accidental. The company immediately advertised the adapter as a replacement for models that were previously successful in sales due to its price-quality ratio. As a result, the owners of GeForce 9800 GT and GeForce GTX 460 had the opportunity to purchase an updated version of the accelerator. And given that the new product still exceeds the old models by 2-3 times, such a purchase would be successful.gtx 660 ti specifications

The type of memory graphics card received GDDR5, volume - 2 GB. She worked at frequencies up to 6008 MHz. Increase energy efficiency greatly failed. But the new card began to consume 140 watts, which is 10 watts less than in previous models.And the main advantage of this novelty was its cost - in Russia at that time it could be purchased for 8-9 thousand rubles.


It is known that NVIDIA is trying to produce reference video cards. But a huge number of manufacturers still develop models to their taste with their own design and in some cases with factory overclocking. As usual, Asus, Zotac and Gigabyte took leading positions among the production of modifications. Consider every detail.

Modification Asus

This company decided not to dwell on one version and created as many as 4 variations of the Asus GTX 660 model. Their characteristics practically do not differ. The difference is only in the frequencies of the graphics core, as well as the GPU Boost. Also, the frequency of video memory has changed a little. Yet the main version of all is considered ASUS GeForce GTX 660 DirectCU II. By the way, in the Game version, in addition to improved features, there is also a game disc. gtx 660 2gb specifications


But back to the main model of ASUS GeForce GTX 660. The box retains the manufacturer’s style. She is not big. As usual, the front has information about the main characteristics, including the name of the cooling system, the amount of memory, and the availability of software for overclocking.

On the back are various specifications.also wiring diagram. There are recommended system requirements. In the box of each version are the same components. As usual, there is a CD with drivers and utilities, instructions and one adapter for VGA.


As mentioned earlier, modifications of the reference video card usually have slightly improved performance indicators, but most importantly, the appearance. Each company has its own style. The new model from Asus GTX 660 was no exception. Design specifications have changed a bit.

The printed circuit board got a different look. The components have become better, another power converter has appeared, and the board itself is 25 cm long. The cooling system has also become special. From the name it is clear that this is a proprietary technology DirectCU II. It takes up two slots, and is slightly longer than the board itself.

The system consists of a casing with two fans and a massive grille of 42 aluminum plates. Copper pipes are used for heat distribution. In general, cooling works efficiently. At maximum load, the temperature rises to 62 degrees. In this case, the cooler only works at half power.If you run it at maximum power, the temperature drops to 52 degrees.

Like all versions, this one runs on the GK106 core. The model supports DirectX 11. Memory type - GDDR5, frequency - 1502 MHz. The core operates at a frequency of 980 MHz. The total amount of memory - 2 GB. This version is considered almost a reference among all. It does not have factory overclocking, and therefore all possible frequencies received the same value.

But the overclocking potential did not show over the results. Still, the graphics core was accelerated by 7% to 1048 MHz. If you connect the GPU Boost technology, you can increase this figure to 1100 MHz. Video memory also improved by 10%, and its value increased to 6608 MHz.

It is worth saying that it was this version from “Asus” that showed the weakest overclocking result. But the GTX 660 DirectCU II TOP with a small factory acceleration reached the frequency of 1130 MHz.

The brainchild of Zotac

This company decided to dwell on two variations of the GTX 660. Their characteristics differ due to the fact that the version of the GTX 660 AMP! Edition received factory overclocking. The appearance of this model is suggestible. The novelty looks solid, resembles a gaming device. The distinctive feature was the corporate design of the housing with an open cooling system.

By the way, it is represented by a radiator with two copper tubes of the heat sink.In a plastic casing there are two orange-colored fans. By the way, there is a separate radiator for parts in the power system.


From the Zotac, the GTX 660 graphics card initially got better than in the reference version. She still works on the GK106. The clock frequency is 993 MHz, the number of stream processors is 960. There are also 80 pieces of texture units. The type of memory has not changed, the volume is also 2 GB. The frequency is 1502 MHz.asus gtx 660 Specifications

The potential of the model from this manufacturer is. She showed herself well at home improvement. The frequency was increased from 993 MHz to 1093 MHz. Video memory has also improved to 7008 MHz.

Powerful version from Gigabyte

Another variation of the GTX 660 2Gb card immediately got improved characteristics. It is associated with an excellent cooling system, and with factory overclocking. Packaging, as always, is quite presentable and of high quality. Everything is done in a laconic style. The front shows the Gigabyte logo, also indicates the memory size, type, graphics core and factory overclocking. The special cooling system WINDFORCE is also mentioned.

Video Card Features

The adapter from Gigabyte Geforce GTX 660 has received excellent characteristics. Many users chose the opinion that this option is the best. He, like the previous ones, works on the GK106 chip, which is made according to the technology of 28 Nm.It contains 960 universal processors. The exchange of information passes through the bus bit 192 bits. Video memory runs on GDDR5 standard with a memory capacity of 2 GB. By the way, the drive consists of eight parts, which have 256 MB of memory. Developed by the company SAMSUNG.geforce gtx 660 Specifications

As mentioned earlier, the feature is the cooling system. It is made by proprietary technology, is much more efficient than the reference. There are four heat sink tubes. It is important that they are soldered to the base and radiator, so the whole system is quite effective.


Since the cooler works well and is more than coping with the maximum load, an additional cooling system is not needed to overclock the video card. In addition, the graphics chip clearly has enough potential for good overclocking results.

As a result, Gigabyte Geforce GTX 660 received the frequency of the graphics core 1086 MHz, increased the speed by 5%. Memory has improved by 13%, and its frequency is equal to 6816 MHz. At the same time the temperature did not exceed 62 degrees.


Geforce GTX 660 has received mixed reviews. Someone expected from her unprecedented overclocking potentialothers hoped for better performance with the new processor. Nevertheless, the company wanted to fill an empty place in the line with this model, and she did it.

Now reviews about the adapter still remain positive. At the present time, not everyone has enough two gigabytes. And yet the card copes with modern games, only sometimes there is a drawdown of FPS because of the new bus width. On the reference version and its modifications, most buyers respond well. Most often praise the low heating temperature, quiet operation and performance.gtx 660


Of all the modifications that were available to the user, the GTX 660 graphics card was the most productive for Gigabyte and Asus. As for the latter company, we are talking about the ASUS GeForce GTX 660 DirectCU II TOP Game. It is this game model has become more pumped out of four. The frequency of video memory was 6108 MHz, and the graphics core operates at a speed of 1072 MHz. In addition, a nice addition to this model was the game as a gift.
