ASUS TUF GeForce GTX 1660 Review.

Video card review and test.

The ASUS TUF GAMING gaming component line has been around for several years and is constantly expanding with new components. Products manufactured under this logo have established themselves as one of the most reliable, as many additional checks are made during production. Therefore, in a conventional system unit, these components will work stably under any conditions, even at + 40 degrees of summer heat, even if the Arctic Circle is cold.

ASUS TUF Gaming GeForce GTX 1660 boasts compact dimensions, high-quality components and good overclocking potential.

In the box

The video card comes in a small cardboard box, the appearance of which is fully consistent with the concept of the TUF Gaming line.
Inside the box, the video card is securely fixed in a cardboard tray and packed in an antistatic bag, and is also protected by a foam lid.
In addition to the video card itself inside the box, an instruction manual and a disk with drivers and proprietary software.


The design of the ASUS TUF Gaming GeForce GTX 1660 graphics card is very different from what we are used to seeing in other lineups from ASUS, such as ROG Strix, Dual and Turbo. The design of almost all devices of the TUF Gaming line has a slight note of militarism. Both motherboards, and peripherals, and now here are video cards, are painted in camouflage camouflage. Of course, this is partially done, but still camouflage is a visiting card of the TUF Gaming line.

The video card ASUS TUF Gaming GeForce GTX 1660 is made with a traditional layout. The printed circuit board is hidden from the outside world with a decorative plastic cover on all sides. And the cooling system here is not quite standard, but about it a little later.

The video card is made in a dual-slot version and has dimensions - 205 x 123 x46 mm.

The plastic casing hides from us not only the front side of the printed circuit board, but also its rear part. The solution is not quite standard. On the one hand, it increases the strength of the video card, protecting it from sagging, but at the same time slightly worsens the cooling of the components of the video card. And all due to the fact that this plate is made of plastic, not metal. The metal would dissipate heat without even touching directly the circuit board, by means of natural convection. But plastic, on the contrary, shields the heat back to the circuit board.

Despite the fact that the casing seems to be a single whole, there are small openings below and above through which the hot air from the radiator goes beyond the internal volumes of the video card.

There are three video outputs on the interface panel:
- DVI-D;
- HDMI 2.0b;
- DisplayPort 1.4.

Additional power for the ASUS TUF Gaming GeForce GTX 1660 graphics card is supplied through one 8-pin PCIe connector. Given the energy supplied through the PCIe 3.0 x16 slot, the video card can consume up to 225 watts. During testing at standard frequencies, the video card consumed about 120 watts, and after overclocking, its power consumption increased to 130 watts.

The cooling system of the ASUS TUF Gaming GeForce GTX 1660 is quite simple. A radiator with radial fins is in contact with the GPU; it is blown by a pair of fans mounted on a plastic casing. Two 76 mm fans are manufactured by FirstD and are powered by a 12 volt line. The fan speed ranges from 1,000 to 4,000 rpm.

And it looks like the front of the printed circuit board of the video card. It is clearly seen that the heatsink cools only the graphics processor and memory chips, but the power system does not have its own heatsink and is content with only blowing one of the fans.

The plastic panel covering the back of the circuit board is easily removable, it does not come in direct contact with the circuit board.
The main radiator of the cooling system is a small aluminum block, into which a copper cylinder is pressed into contact with the graphics processor. The radiator fins have a well-established radial shape, which Intel widely uses in its boxed coolers. The radiator itself is quite compact, its height reaches only 20 mm. By the way, the radiator contacts not only the GPU, but also removes heat from the GDDR5 memory chips. For this, soft thermal pads are used.

The printed circuit board of the ASUS TUF Gaming GeForce GTX 1660 is quite compact, the power system is located to the left of the GPU. I would also like to note that this PCB, like the printed circuit boards of other video cards, is manufactured using Auto-Extreme technology. Thanks to it, all the elements are perfectly aligned and there are no tin smudges on the board. And this happens due to the fact that all components are soldered at a time, so the board is not exposed to repeated heating and exposure to strong chemicals when washing by-products of soldering.
The heart of the video card is the NVIDIA TU116-400-A1 graphics processor. It is manufactured according to the 12 nm process technology and boasts the presence of 1408 CUDA cores, 48 ROP units, 88 TMU units. The nominal clock frequency of the GPU is 1530 MHz, with automatic increase to 1980 MHz in Boost mode. Information exchange with GDDR5 memory is carried out via a 192-bit data bus.

Around the GPU, six GDDR5 memory chips are soldered, they are manufactured by Micron and are marked 8KB77 D9VVR. Their nominal frequency is 2000 MHz (8000 MHz effective).

The power supply system for the ASUS TUF Gaming GeForce GTX 1660 OC Edition graphics card has 5 phases, they are made according to the 4 + 1 scheme. Four phases are dedicated to power the GPU and one phase to power the memory. Here, SIC638 assemblies are used as power microcircuits, which can withstand currents up to 50 A, and one FDPC5018SG microcircuit, designed for a load of up to 32 A. The operating temperature regime for all microcircuits can reach 125 degrees.

The converter is controlled by a uP9512R digital PWM controller.

Testing ASUS TUF Gaming GeForce GTX 1660

Test stand:
- Intel Core i5-8600K processor
- Corsair Vengeance LPX DDR4-2800 RAM
- Motherboard ASUS ROG Maximus X Apex
- Power supply Corsair AX1200i.

Video card testing is divided into two parts, at first the video card passed tests at nominal frequencies, then the same tests were carried out at higher frequencies. The graphics processor was able to overclock from 1530 MHz (1980 MHz Boost) to 1510 MHz (2175 MHz Boost), the GDDR5 memory overclocked from 2000 MHz to 2400 MHz. In the absence of load, the video card resets the GPU frequency to 300 MHz, and the memory slows down to 202 MHz.

Game testing


This model is an interesting solution due to a number of factors. Firstly, this is one of the most affordable versions of the GeForce GTX 1660 graphics card in the ASUS lineup. At the same time, for a reasonable price you get not only a high build quality and a guarantee of work in any, even the most severe conditions, but also a nice design, as well as excellent overclocking potential.

This may sound strange, but the ASUS TUF Gaming GeForce GTX 1660 graphics card, despite the lack of a radiator on the power system, showed the best results in overclocking the TU116 GPU. Plus, to this you get a nice look.

We can safely recommend the ASUS TUF Gaming GeForce GTX 1660 graphics card for purchase. It has one of the best price / quality ratios.
