Gigabyte has long been decided to create their own gaming brand that we know how Aorus. Under him there were many gaming notebooks and peripherals, but Gigabyte is planning to use Aorus to release video cards and motherboards. In our test lab just received the video card Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G, which can be called the first representative of a new brand.
Pascal generation NVIDIA has been very successful. The flagship of the new line has become the GeForce GTX 1080 despite the relatively high price it sells well, which enabled NVIDIA to make a decent profit. Later, NVIDIA has released a mid-range model GeForce GTX 1060, the GTX 1050 Ti and GeForce GTX 1050, which provided a significant share of sales in the market.
Pascal Generation interesting by the fact that NVIDIA has removed the distinction between desktop and mobile graphics processors. Of course, GPU in notebooks is still limited to the cooling system and the TDP, but theoretically, the mobile GeForce GTX 1080 is no different from the desktop version. By the way, under the brand Aorus out laptops GPU Pascal.
Nine months after the emergence of GPU Gigabyte has decided to release to the market another model GeForce GTX 1080 that certainly related to the promotion of the new brand. In fact, Gigabyte GeForce GTX 1080 xtreme edition 8G is quite close to the graphics card Gigabyte GeForce GTX 1080 Xtreme Gaming, which we tested last July.
In our video card section, you can find a large number of reviews GeForce GTX 1080. We tested the model with different cooling systems, although the majority of graphics cards are equipped with a classic cooler.
The new graphics card GeForce GTX 1080 architecture does not differ from other models. GPU GP104 is based on the 2,560 stream processors, chip contains 7.2 billion. Transistors and manufactured on 16-nm process technology. 8 GB memory GDDR5X connected by a 256-bit interface. 2,560 stream processors, 160 texture units are complemented and 64 ROP.
Of course, there are differences in frequency. NVIDIA reference card to put a base frequency 1.607 MHz, Gigabyte’s model, we get 1.759 MHz. More interesting frequency Boost – at Founders Edition NVIDIA put the minimum bar 1.733 MHz, Gigabyte video card indicated for Aorus 1.898 MHz. Staffing Gigabyte card works in Gaming mode. But you can also select Silent mode, which reduces the clock frequency of the graphics card to the standard and is quieter. However, gamers will certainly appeal to OC mode in which the graphics card increases the clock frequency to 1.784 / 1.936 MHz. As with all other cards with similar switching modes, we tested the Gigabyte GeForce GTX 1080 xtreme edition 8G at the highest clock speeds, that is, in the OC mode.
Silent Mode: 1.607 / 1.733 MHz
Gaming Mode: 1.759 / 1.898 MHz
OC Mode: 1.784 / 1.936 MHz
Besides the GPU Gaming Mode accelerates and memory – up to 2.550 MHz, 2.500 MHz instead of standard. In the OC memory runs at 2600 MHz.
If you are interested in the details of the architecture, we recommend that you read an overview of the GeForce GTX 1080, in which we discussed in detail the architecture of Pascal, a 16-nm process technology and FinFET new features.
GPU-Z screenshot confirms specifications Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G. Here the video card worked at the Gaming mode.
In our tests, the GPU new, whether it’s from AMD or the NVIDIA, we have repeatedly said that the video card performance affected by temperature and power consumption. What can be clearly seen by the results of GeForce GTX 1080 consolidated first test.
Under load the game Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G must run at speeds of at least 1.936 MHz – if the graphics card is not limited by restrictions on the temperature and power consumption. Our GPU tests are not heated above 69 ° C, so the limiting factors have power – we have not received frequencies above 1.999 MHz. In any case, the graphics card can be called one of the fastest in our test lab. It will be interesting to see the results of overclocking.
The length of the video card Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G is 288 mm, so it can not be called a compact, although it fits the ATX specification. According to the thickness of the card takes 2.5 slots. Below we consider other details, including the power system and additional power connectors.
Massive video card cooler immediately catches the eye. However, in addition to PCI Express slot PCB itself is almost not visible. Aorus logos are located on all three fans. Above average fan is located cross, which is attached to the fan motor. Below we will return to it.
Behind you can see the first difference from the video card Extreme Edition, instead of solid black back plate Gigabyte adds an interesting copper insert for the GPU. And on the left you can see the logo Aorus backlit. lighting work, we have shown in the video. However, RGB LED lighting has become the standard of modern graphics cards. Whether you like it or not – decide for yourself.
Three fan Gigabyte GeForce GTX 1080 Xtreme Gaming have a diameter of 100 mm. In idle state, they are stopped. Namely, when the GPU temperature falls below 42 ° C. Under load, the fans are switched on after the GPU heat up to 54 ° C, the maximum rotational speed of 1,780 rev / min.
Since three of the fan diameter of 100 mm in the length of the video card is simply not fit, Gigabyte had to shift the average fan down. Given the thickness limitation, Gigabyte did the average fan impeller thinner. When viewed from above, the fans hanging over each other. In addition, the average fan is rotating in the opposite direction, which increases air flow.
With two SLI connectors can be combined into multi-GPU configurations up to four graphics cards. But in practice, a configuration with more than two graphics cards are very rare. The advantages of such systems can be assessed in the reviews of our two GeForce GTX 1080, 1070 and the GTX NVIDIA Titan X.
Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G is equipped with two 8-pin auxiliary power. According to the specifications of each allows feeding of up to 150 watts of power. With 75 watts of PCI Express graphics card slot can receive up to 375 watts of power. This level is more than sufficient for normal operation, and the dispersal of power will not be limited. There are also quite critical power system, which should provide a stable supply voltage on the GPU, memory and other components.
With the end of the video there is another component to light. Namely Aorus logo and the inscription on the right – they, too, are illuminated RGB LED. To the right is added Fan Stop indicator indicating a stop of fans. So that the user will always be able to check the status of the fans.
At present slot plug 3x DisplayPort 1.3 / 1.4, 1x HDMI 2.0b and 1x Dual-Link DVI. They make it easy to connect to virtually any monitor on the market, through the DisplayPort (and adapters) can be assembled configuration with multiple monitors. The photograph raised noticeable cooler, which takes more familiar of the two slots.
At the rear of the video card can be seen two HMDI terminal. Such a feature called Gigabyte VR Link. With complete HDMI cables and 5.25 “two HDMI output module can be displayed on the front panel of the case, which will optimally connect the VR goggles, like HTC Vive and Oculus Rift, given the limited length of the cable. The EVGA also offers a similar feature on some of their graphics cards. The card determines when the user connects the HDMI device that disables the ports on slot plug.
The cooler is noticeably larger PCB graphics card, and he acts on the length and the width. In the photo you can see the ends of the five large heatpipes.
Another photo backdrop graphics with backlit logo. Gigabyte used a panel of Plexiglas, which scatters the light from the RGB LED, so it seems that the surface is illuminated uniformly.
Here we will continue the detailed examination of the video card.
One of the distinguishing features of the graphics card – the back plate with a copper insert for the GPU. This measure allowed Gigabyte to reduce the number of hot spots in the field. Of course, the practical benefits can argue long. The back really strongly heated, but no differences in GPU temperature, we have not found.
After removing the cooler PCB can be considered in detail. In the left half of the PCB is the GPU and eight memory chips. Right can be seen the power subsystem. Finally, at the far right end of the mounted connectors for additional power supply, connect the backlight, two HDMI ports.
On three sides around the GPU has eight Micron memory chips. Recall that Micron is the only manufacturer to offer a memory GDDR5X NVIDIA and partners. It is not entirely clear what the prospects have GDDR5X memory in the future, whether we are a new stage of development will see the memory, such as GDDR6. In any case, in the high-end segment will be important to memory High Bandwidth Memory 2nd generation. And this year, it must penetrate the desktop segment.
Gigabyte has chosen to Aorus GeForce GTX 1080 xtreme edition 8G 14 + 2-phase power system. Single Load Balancer chip provides load balancing between phases of power. There is also a protection against overheating. Of course, Gigabyte indicates the use of only the highest quality components. Powerful power system with 14 + 2 phases allows to hope for decent overclocking results, including those with water cooling. But it seems to us, significant benefits can be seen only when cooled with liquid nitrogen.
In the rear area there are additional PCB connectors connect lighting and power. It can be noted and several shunts – low resistance resistors that are used to measure current.
To remove the back plate should be careful not to tear the RGB-backlight cable – it has to be carefully disconnected from the socket. However, most buyers are unlikely to take off the back plate. Backlight with distribution panel is attached with adhesive tape.
Without rear plate can consider the entire PCB. But there is nothing unusual except for a copper plate. Clearly visible point of soldering the power subsystem components. On the left are arranged connectors PCI Express auxiliary power. In general, PCB size is much higher than the typical size of the graphics card.
The picture may be better to consider a small copper plate. It is designed to absorb and dissipate heat generated by the GPU video card behind.
The cooler the video card uses a large copper plate that is in contact with the GPU and memory chips. But the plate is not in contact with the components of the power subsystem.
As Fingerprint crystal copper plate on its small size are clearly visible. Only a small portion of the plate in contact with the GPU. Eight memory chips heat is removed via the heat-conducting pads.
From the power subsystem components, heat is removed on a small aluminum heatsink. The heat from the copper plate is transferred to the aluminum radiator with six copper heat pipes.
With the help of the utility you can set different modes of video performance. Also modes Silent, Gaming and OC still has a manual, which the user can set the clock speeds at their discretion. And the graphics card will be loaded with the selected frequencies.
Like many modern video cards tested model Gigabyte off three fans at idle when the GPU temperature drops below 42 ° C. As a result, the graphics card works in passive mode absolutely noiselessly. Note that when you stop the fan corresponding indicator lights up on the end of the video card.
Under load the video card is located in the middle of the rankings, even closer to the quietest model GeForce GTX 1080. Some video cards work more quietly, but they do not approach the level of performance Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G. Apparently, Gigabyte successfully optimized the operation of the fans.
In idle mode, the temperature was 42 ° C, just under this level will turn off fans. If the video card hold in idle longer, the temperature is even lower. But according to our method, we measure the temperature after 20 minutes of inactivity. In any case, fans are starting to unwind GPU when heated to 54 ° C, therefore any problems we encountered.
Under the GPU load is not heated above 69 ° C. Therefore Boost frequency is not limited temperature and power consumption Power Target. Of course, the temperature of 69 ° C gives some margin to reduce fan speed under load, whereby the card can operate more quietly and GPU temperature will increase slightly.
In idle mode between the GeForce GTX 1080 the difference is small. They reset the clock frequency and voltage to a minimum, which leads to approximately the same level of power consumption.
Under load graphics cards consume much more as higher clock speeds are accompanied by a high voltage level. But Gigabyte model performs at the level of the competition, we would not be called excessive power consumption.
With connecting multiple monitors problems have arisen. System power consumption increased slightly.
Gigabyte has decided to strengthen its gaming brand Aorus, under which the market is now out and the video card. Brand Aorus focused on high-end gaming segment, so it is quite logical manufacturer introduced the first graphics card GeForce GTX 1080. However, with the Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G we do not get an entirely new model, similar graphics card we tested nine months ago.
However, differences still exist, but they boil down to different sticker on the fan and the new copper plate for the GPU. Instead of solid aluminum plate behind, the manufacturer has added lighting and said copper insert. In practice, any benefit from such a step, we have noticed. As well as on the GPU temperature changes. Of course, under a load of copper insert noticeably heated, it takes away some of the heat from the GPU, but with the same task perfectly cope and aluminum back plate.
As for performance, Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G refers to the fastest air-cooled models. The card has a decent factory overclock, but you can squeeze a little more. Faster will be except that a water-block model (closed loop or in full CBO), they will provide a slightly higher clock speeds. But the difference is small, so you should think carefully whether it makes sense to pay extra for the CBO.
During the cooling Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G meet three fans that stop in the sleep mode. As a result, the graphics card works completely silently. Even under load the video card worked relatively quiet, and the GPU, and the temperature was quite low. So the complaints we did not have, but the fans certainly quieter systems can optimize fan operation.
A nice addition was the RGB-lighting. Gigabyte went to her quite seriously. Lights cross on the front of the video card, the logo on the face and on the back plate. And all the lighting elements can be controlled by the utility. Gigabyte supports different effects. Also, through the utility can squeeze more performance out of the graphics card. For example, we put OC mode, in which tests were carried out. You can also set Gaming mode and Silent.
In the retail Gigabyte Aorus GeForce GTX 1080 xtreme edition 8G will cost 799 euros or 50 thousand. Rubles in Russia. We have before us one of the most expensive models with air-cooled, but the graphics card provides an excellent level of performance.
