Slowly but surely, the range of video cards Radeon RX 480 is expanded. In our test lab received one of the newest models – Gigabyte Radeon RX 480 G1 Gaming 8G. It is unlikely that in the future, Gigabyte plans to release new versions of Radeon RX 480, so the card can be considered as the completion of the line. It will be interesting to evaluate its strengths and weaknesses.
AMD officially introduced the Radeon RX 480 back in early June, although the first graphics cards began to appear only on 29 June. But it took several more weeks before the video became available in large quantities at reasonable prices. This situation can occur for two reasons: either the demand for AMD cards exceeded expectations, or the company could not deliver a sufficient amount of GPU to its partners. For consumers, the reason is not so important. But at least now you can get an effective and decent mid-range graphics card at a reasonable price.
Gigabyte put frequency of the GPU graphics card Radeon RX 480 G1 Gaming 8G at 1.290 MHz, which is slightly above the 1.266 MHz in reference model. In addition, the Gigabyte video card frequency inferior to many competitors who nominally GPU overclocked to 1.306, 1.330, or 1.338 MHz. However, all the cards are pretty close to each other, AMD does not allow producers to seriously stand. So it is unlikely to choose Radeon RX 480, based on the maximum frequency. We believe that the cooling system is still important here.
Other technical specifications of Gigabyte Radeon RX 480 G1 Gaming 8G do not differ from its competitors. 8 GB of GDDR5 memory clocked at 2,000 MHz, the connection is carried out on a 256-bit bus. As a result, the bandwidth of 256 GB / s. The GPU frequency work 2.304 GPU stream processor Polaris 10, last performed on 14-nm process and contains 5.7 billion. Transistors. Among other architectural details note 144 texture units and 32 ROP raster operations pipeline. Typical power consumption is 150 watts, but in the case of Gigabyte Radeon RX 480 G1 Gaming 8G it may be a little higher.
If you are interested in details about the architecture of Polaris, we encourage you to read our first review of the reference Radeon RX 480. AMD has transferred the production of new chips on 14-nm process FinFET, which should positively affect the 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. Although AMD situation is not as intense, less capacity is limited in the cooling system, and other constraints, unlike GPU NVIDIA.
WindForce cooler on the graphics card Radeon RX 480 G1 Gaming 8G coped with cooling the GPU under load up to 78 ° C. The level is not the lowest, but not critically high. It is important that the GPU temperature does not exceed the allowable threshold, otherwise it will be activated throttling. Video card Gigabyte Radeon RX 480 G1 Gaming 8G always operated at the maximum stated frequency 1.290 MHz.
Before we move on to a detailed examination of Gigabyte Radeon RX 480 G1 Gaming 8G, let me give you a cooler specification, PCB, etc.
Video card Gigabyte Radeon RX 480 G1 Gaming 8G looks quite modest, and it does not stand out on the characteristics. PCB slightly shorter than the cooler, which is a bit exposed. With a length of 235 mm card belongs to the most compact models Radeon RX 480 on the market. The thickness of the usual two slots. Below we will consider in detail the cooler and interfaces.
Gigabyte chose a fairly simple design. video components, namely PCB and cooler, painted black. Variety of making red accents. However, the appearance is not so important, much more interesting possibilities and graphics cooler.
Behind Gigabyte has established a solid metal plate. It provides additional mechanical strength and protects the card. The plate can be seen except the Gigabyte logo. On the left it is clearly seen that the cooler is exposed beyond the PCB.
Two WindForce cooler fan has a diameter of 85 mm. The shape and profile of the blades with protruding ribs are designed to optimize the air flow to reduce turbulence and noise. According to the Gigabyte, this form provides air flow and fan center where conventional models formed “dead zone”.
Two fans are beginning to work with GPU heated to 50 ° C, after which they slowly build momentum. If the GPU starts to cool, the fans are stopped when the temperature reaches 44 ° C. The difference between the two temperatures ensures that the fans will not operate in an endless loop on / off.
In the standard version Radeon RX 480 power system has been implemented it is not entirely correct. AMD to correct the situation with a driver update, but the graphics card manufacturers have decided to err by increasing the power supply interface. Gigabyte Radeon RX 480 for the G1 Gaming 8G chose 8-pin auxiliary power. Together with the PCI Express graphics card slot gets more than enough power for the calculated energy consumption just above 150W.
Next to the slot flap can see contacts for CrossFire, but in the case of Polaris cards such connection is not provided. On the left you can see the extra touches, but did not install the Gigabyte BIOS toggle switch, which is available on some models Radeon RX 480.
Behind the video is clearly visible hanging over the PCB cooler. The length of the video card Gigabyte Radeon RX 480 G1 Gaming 8G is 235 mm, so that it can easily fit even in compact housings. Theoretically, the graphics card Radeon RX 480 can come in mini-ITX format 170 mm in length, but manufacturers have not yet released a similar model.
WindForce cooler removes heat from the GPU using three copper heat pipes. Large aluminum base cools the GDDR5 memory chips and components of the power subsystem. So Gigabyte cooler removes heat from the main components.
In the slot cap can be seen the familiar interfaces that allow you to connect all modern monitors, as well as future models for 2-3 years. The buyer will receive a two-channel output DVI, which can be called hereditary, but AMD also has provided more recent standards DisplayPort 1.3 / 1.4 and HDMI 2.0b. DisplayPort outputs 1.3 / 1.4 available in the amount of three pieces, HDMI is set in the singular.
Gigabyte has equipped graphics card Radeon RX 480 G1 Gaming 8G RGB backlight. It is found in almost all modern video cards Gigabyte, the implementation is similar. Therefore, here we will give a reference to the review of GeForce GTX 1080 G1 Gaming, where you can see the lights in the action.
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.
In idle mode, Gigabyte Radeon RX 480 G1 Gaming 8G showed a fairly high temperature of 44 ° C. The reason lies in stopping the fan, so any problems we do not see here. Temperature will stop just at the level when the fans are turned off. We conducted a 30-minute test, but the GPU temperature is not increased.
Under load, the GPU temperature increased to 78 ° C, is a video card Gigabyte Radeon RX 480 G1 Gaming 8G performs at the level of competitors. Of course, some models work with a lower temperature, but part of competitors GPU shows higher temperature. Temperature is not critical, throttling rate we got, so that any problems we do not see here.
The idle power consumption video show on a fairly intimate level, the winner here can hardly be distinguished. Other components of the system affect the power consumption more than the card. Therefore, it is hardly worth making a decision about choosing a video card based on this criterion.
Under load, power consumption increases, we receive a significant difference between the video cards. Gigabyte Radeon RX 480 G1 Gaming 8G together consumed 316.3 watts with the test systems. Frequency slightly below other models Radeon RX 480, and therefore power consumption less. If performance is comparable, then we get a very efficient video card.
Test 3DMark from Futuremark – one of the most popular synthetic benchmarks, it allows you to conveniently compare different systems or individual components. Individual modes (Preset) allow to evaluate different aspects of the system work – up to the resolution UltraHD / 4K. The test was originally developed for DirectX 11, but today 3DMark also allows you to evaluate the optimization for DirectX 12, analyzing the number of calls Draw calls.
Luxmark 3.0 – rendering test, which is based on the OpenCL interface and broad base of hardware cards. Luxmark designed as a test measure the performance LuxRender. To calculate the scene used LuxRender 2.x API. The result is given in samples per second.
In GPUPI test is calculated pi through different interfaces. Programs such as SuperPi, have long been used to evaluate the performance of computer “iron” can be calculated through the processor and graphics card. As seen on GPUPI title, this test is based calculation on the GPU. We used the OpenCL API and calculated pi to 500 mln., Or 1 billion. Marks. GPUPI allows convenient appreciate the 64-bit performance, “iron”.
Manufacturers gradually released the video card Radeon RX 480 in all of its product lines. Mock Gigabyte Radeon RX 480 G1 Gaming 8G was the finishing touch Gigabyte. We have tested a lot of models Radeon RX 480, among which you can choose the graphics card with higher overclocking potential or silent cooling system.
Gigabyte has focused on the cooling system, since the frequency of 1.290 MHz inferior to many competitors. Only the reference version of the Radeon RX 480 runs more slowly. Graphics cards from ASUS, HIS, Sapphire and PowerColor are working at higher clock frequencies, resulting in a corresponding separation performance in the tests. Video card Gigabyte Radeon RX 480 G1 Gaming 8G version can be called Radeon RX 480 with the low level of factory overclocking. The GeForce GTX 1060 of the “green” camps are also usually faster.
Gigabyte fans off in idle mode when the GPU is cooled to 44 ° C. This level is very close to the temperature in the sleep mode, but the fan start to rotate only upon heating to 50 degrees GPU. As a result, the graphics card under minimum load is silent.
Under load, the noise level is very low, only the best results demonstrates the PowerColor model. As a result, Gigabyte Radeon RX 480 G1 Gaming 8G was one of the quietest cards in this segment. In idle mode, the temperature of 44 ° C is relatively high, but any problems we do not see this, because the fans are stopped. Perhaps fans will have to work a little longer to cool the GPU up to this temperature, but the result is still one. GPU temperature under load is increased to 78 ° C, which is below the critical level. Power consumption remains within reasonable limits. So the graphics card Gigabyte Radeon RX 480 G1 Gaming 8G successfully coped with our tests.
From the distinctive features video card can be noted RGB-illumination. It allows you to configure the card for themselves with the help of software, various modes are available. If the lights you are not interested, you can simply turn off. Second BIOS there, but it is not so necessary, since the frequency and fan profiles are configured by software.
Price Gigabyte Radeon RX 480 G1 Gaming 8G is from 19.3 thousand. Rubles in Russian or 279 euros in Europe. What is slightly more expensive than the cheapest model with 8 GB of video memory. You will receive an excellent cooler and higher performance version of the standard, so the card can be safely buy.
