So far, in our test lab I have visited only one graphics card Radeon RX 470, but it is worthy of a great deal of attention. Despite the proximity to the Radeon RX 480, the card will allow to save a little, although it all depends on the specific model. We tested Gigabyte Radeon RX 470 G1 Gaming 4G, it is better to allow the consideration of its appeal compared to the Radeon RX 480.
With the generation of Polaris AMD attacks the middle class. The price range of 10-15 thousand. Rubles is quite interesting for manufacturers, because it sold most video cards, so the profit is very high. Consumers choose the RX 470 and the Radeon Radeon RX 460, as well as the other models in this range, because of attractive prices, but still sufficient performance.
As in the case of the “older” Radeon RX 480 on Radeon RX 470 GPU Polaris set 10 which has the chip 232 mm² area. Unlike the Radeon RX 480, the video card Radeon RX 470 is available only 32 Compute Units unit. Each CU uses 64 stream processors, which gives 2,048 stream processors in Radeon RX 470.
Compared to reference graphics card maker has increased the clock speeds. And it is up to 1.230 MHz to 1.206 MHz. In the case of Polaris have to get used to such a slight increase in clock speed, although NVIDIA graphics cards with Pascal was able to achieve higher clock frequencies, so the difference between the more extensive graphics partners. All theoretical specifications, including the amount of memory and the frequency correspond to the standard version.
If you are interested in the details of the Polaris architecture, we recommend you to read our article on the Radeon RX 480 . AMD has transferred the production of 14-nm process technology FinFET, which has a positive impact on efficiency.
As shown by numerous tests with the new GPU, whether it’s from AMD or NVIDIA, the performance of graphics cards with alternative cooling systems significantly influence the clock frequency and temperature. But in the case of video cards AMD situation easier because they are not quickly matched to extreme temperatures, as many models on the GPU NVIDIA.
Gigabyte Radeon RX 470 G1 Gaming 4G reached the maximum frequency Boost 1.230 MHz in all tests. What it is due to the fact that the cooler was able to keep the GPU temperature in the range of 73-74 ° C. Therefore PowerTune mechanism does not reduce the clock frequency and voltage. In the case of Gigabyte Radeon RX 480 Gaming 8G the G1 the GPU temperatures were slightly higher.
Before we move on to a detailed examination of the video card Gigabyte Radeon RX 470 G1 Gaming 4G, let me give you the basic specifications of the cooler, PCB, etc.
Gigabyte used the same basis for the graphics card Gigabyte Radeon RX 470 G1 Gaming 4G, as for the Gigabyte Radeon RX 480 Gaming 8G the G1 . Therefore, the printed circuit board again has a length of 220 mm, a length of cooler is 235 mm above it hangs. Gigabyte chose a dual-slot design, so the card takes up two slots. Extra power is supplied through one 8-pin and two 85-mm fans provide fresh air. For more information, we present below.
Gigabyte used a uniform design for its line of Gaming. Cooler, mostly black, but Gigabyte adds red insert. The rest is nothing unusual. During the cooling corresponds to two 85 mm fans, the length of 235 mm is quite typical for middle-class graphics card.
Behind Gigabyte has installed a metal plate. Holes in it there, unless there is some notches around the edges. For one of the recesses can see the sticker with the serial number. Back plate improves the mechanical strength of the video card. But this is true only for long graphics cards equipped with heavy coolers. In the case of Radeon RX 470 back plate adds more to the beauty and to protect cards from damage.
Two fans have a diameter of 85 mm. The shape of the blades and the ribs are designed to optimize air flow and prevent turbulence reducing noise. As pointed out by the Gigabyte, fans provide airflow, including the area under the center. Which many other fans remains a “blind spot” with no fresh air.
Two fan start working GPU when heated to 50 ° C temperature, after which the rotation rate begins to increase slowly. If the GPU graphics card is cooled to 44 ° C, the fans stop. The difference in the two values prevents a continuous cycle stop / start the fan.
Extra power is supplied via the 8-pin socket. According to the specifications, it can provide power up to 150 watts, which is more than enough to power the video card even without a PCI Express slot. AMD indicates TPD at 120 watts, hardly Gigabyte video card it significantly exceeds – at least in a normal state. It is not pleasant to the cable that brings power to the LEDs at the end of the video card. Gigabyte could pave the cable and the cooler.
Gigabyte adds to the Gigabyte Radeon RX 470 G1 Gaming 4G RGB-illumination. Today it is present in almost all producers, therefore, it is no longer something unique. Backlight can indicate, for example, when two video card fan is in stop mode. Here we give a link to an overview of GeForce GTX Gaming 1080 G1 , where we discussed the operation of the software and lighting.
WindForce cooler removes heat from the GPU using three copper heat pipes to the radiator. Large aluminum base in contact with the GDDR5 memory chips and VRM components between the GPU and the slot flap, removing them from the heat. So Gigabyte cooler cools all of the major components of the video card.
At the rear you can see the aluminum radiator. Clearly visible, and the heat pipe, which removes heat from the base of the cooler to the radiator. The photo is just noticeable that overhangs the heatsink PCB graphics card.
In the slot plug has all the usual interfaces through which the next 2-3 years will be connected monitors. Dual DVI interface is already beginning to become obsolete, but AMD has added more modern DisplayPort 1.3 / 1.4 and HDMI 2.0b. DisplayPort 1.3 / 1.4 is present in an amount of three pieces, HDMI only one.
We have updated test suite of games and applications, but the hardware remains, for the most part, the same. To maximize our tests correspond to the average PC gamer, we held them in a closed cabinet. Operating System Windows 10 was installed on the SSD, but we ran the game from your hard drive. Although this detail does not affect the performance.
The video card Radeon RX 470 AMD was planning to introduce a less expensive alternative to the Radeon RX 480. As shown by the first tests, the graphics card Radeon RX 470 10-15% slower than Radeon RX 480 with 4 GB of graphics memory. At high resolutions and quality tinctures Radeon RX 480 with 8 GB of video memory significantly forging ahead. Compared with the previous generation, the Radeon RX 470 is located between the Radeon R9 380X and R9 390.
Gigabyte Radeon RX 470 G1 Gaming 4G delivers the performance slightly above the reference AMD version. Depending on the game and the settings, the opponent may be called GeForce GTX 1050 Ti, but most often it is weaker, because between AMD and NVIDIA are no direct correlation models. The performance of the video card and Radeon RX 470 show similar results, the differences are small. What you can see well than two Sapphire and Gigabyte models. Since Radeon RX 470 can operate with only 4 GB of video memory, the Gigabyte for AMD specification does not come out. 4GB memory limit the performance in many tests.
For the cooling system makes sense to look more, because it can affect the choice of graphics card of a particular manufacturer. The two fan idle stop, the card runs quietly. This function has become very popular in the past year, we can only welcome. Under load, the Gigabyte Radeon RX 470 G1 Gaming 4G might work more quietly, since margin GPU temperatures there. We did not find anything strange in power consumption.
But despite the good impression of the graphics card, the question remains whether the washed fly Radeon RX 470 from Gigabyte or another manufacturer? Price Gigabyte Radeon RX 470 G1 Gaming 4G is 200 euros. Since Radeon RX 480 with 4 GB hardly worth recommending, we should compare the model with 8 GB, the price of which starts from 249 euros. Video Card Radeon RX 480 with 8 GB of memory provides better performance, it also gives the best stock for the future. But if the budget you have limited to 14 thousand. Rubles, and you are an adherent of the “red” camp, then take the Gigabyte Radeon RX 470 G1 Gaming 4G can.
