NVIDIA continues to fill up a new line and for the past three graphics accelerator GTX 1080/1070/1060 took their place in different price segments. For example, all of these models, we can conclude that the company is seriously bent to win an even greater share of the market. Despite the fact that the vast majority interest in budget decisions, many will be watching and more expensive accelerators in the hope of lower prices resulting from competition with AMD’s, if any at all. The time to talk about the monopoly of one producer in the desktop video card segment. But let’s not talk about sad things and to look at the reference model GeForce GTX 1070 from NVIDIA.
According to the NVIDIA’s new architecture is a revolutionary, but is it really? The most striking innovation is the case with PASCAL is a transition to a new manufacturing process of 16 nm. This led to a significant growth in the operating frequency of the GPU, which has led to a marked increase in productivity. Another important feature was the use of FinFET (Field Effect Transistor with Fin) – transistors, so that there was a reduction of energy consumption and increase efficiency. Despite this, the architecture of PASCAL is likely evolution of Maxwell, than something completely new.
Interesting innovations were made and SLI. Now, the company will pay more attention to the tandem of the two accelerators, ie, try as much as possible to optimize the performance scaling is for such a scenario. However, this does not mean that the use of three or even four graphics cards will now be impossible, does not just focus will be shifted in the direction of the most sought after option. It’s no secret that afford a system of three or four cards can only units.
For lovers of multi-monitor configurations, and NVIDIA helmets of virtual reality technology in store lump multiproetsirovaniya (Simultaneous Multi-Projection). In fact, this optimization is designed to carry out a simultaneous blunder geometric data for a number of prefabricated projections. What is it for? Firstly, to eliminate the distortion using various displays or curved displays with multiple configurations. Secondly, it improves the performance for these use cases for your system. Few of us have the opportunity to try out at the time NVIDIA 3D Vision, but those who had a chance, there is a marked lack of performance, as the card went to a double burden when drawing images for each eye. With the introduction of SMP, this problem is eliminated.
Also, one can not but mention two interesting innovations that are titled as Ansel and Fast Sync.
Ansel – an invaluable tool for creating accompanying game content that is useful to tape drives and sponsors various gaming blogs. During the game you can press pause and adjust the camera at any desired angle to create a screenshot. In addition to this you will be available to a number of effects to improve the image, and the ability to take a picture with remarkable clarity. In addition, it is possible to create a 3D image, panoramic 360 ° screenshots and images. The truth should be made clear that it will only be available in those games where the relevant support for this option will be introduced.
Fast Sync – a peculiar addition to a function such as VSYNC. In general, activation of this innovation will allow you to get rid of the delays that occur when you turn on VSYNC. Besides artifacts are eliminated in the form of picture discontinuity that may be noticeable when vertical sync is disconnected. This scenario is valid only if the value exceeds the threshold FPS refresh rate.
To start to define a typical portrait of the consumer. NVIDIA GeForce GTX 1070 has a very decent performance, but is aimed primarily at those who want to comfortably play on monitors with a resolution WQXGA (2560×1440). For Full HD (1920×1080) the performance of a graphics card is redundant, but it is not enough for 4K UHD (3840h2160). Taking into account the average price of 35 thousand, this model will find a lot more fans than the much more expensive GTX 1080. Also, when such value becomes 1070 GTX a great choice for combining video cards in SLI. AMD at the moment there is nothing to say, so any significant alternatives are not yet in sight.
The card arrived on the test without packing. However, box and accessories are no different from those considered previously in the material on the Geforce GTX 1080 Founders Edition. In turn, I want to note that the versions of third-party brands of equipment can be supplemented by all kinds of adapters and accessories or bonus codes for the current game projects.
The design of the accelerator repeats the outlines 1080 GTX with the only exception that the inscription is now pointing to the considered model. In the rest, its length, the number of slots occupied and everything else – remains unchanged. The advantages Founders Edition include the relatively compact dimensions, it allows you to mount the graphics card in the housing of the different form factor. And this is not an empty phrase, for example, look at the non-reference models with a length of 300 mm and trёhslotovoy cooling system.
The undoubted advantages include the provision on the reverse side of the plate that have a positive effect on the appearance of computer assembly and gives additional rigidity to combat sagging card.
As is the case with the 1080 GTX for additional power connection device is provided on one connector pin 8, which is located at the end towards the end of the board. For proper operation, you will need output power supply of 500 watts or higher. It is interesting to observe how with increasing performance graphics cards are becoming more economical in consumption, and on this background is no longer any need for a heavy-duty power supplies. In addition, it should be noted some improvements in the design, in this perspective, in 1070 GTX Founders Edition looks more aggressive and expressive. In addition, the graphics card is equipped with a green light, which can be adjusted via the GeForce Experience application.
In front of a lack of any additional connectors are visible only fins.
Interface Panel unremarkable and repeats the standard array of ports, which we have already met several times on the cards of the previous generation: 3x DisplayPort, DVI-D, HDMI 2.0.
Coolant GeForce GTX Founders Edition 1070 is devoid of any significant changes and corresponds to the previously described material of the GTX 1080. The only difference touched radiator that contacts the graphics processor. If in the case of 1080 GTX used in the base design which was the evaporation chamber, in this case we decided to resort to the use of three copper heat pipes. For heat removal from the chip memory and power transistors, a special plate on which is located at the end of a turbine-type fan. fan impeller is provided with some optimization, which helped reduce noise without reducing air flow.
On the reverse side, to stiffen and protect the circuit board elements, two plates are used. This item is not see at all alternative models, particularly when it comes to budgetary decisions. Thus, the presence beklpeyta has a positive influence on the final form of vernal computer assembly.
The most common graphics card with reference cooling systems are used where it is necessary to deduce the hot air out of the case. Usually this means the operation of the accelerator in compact assemblies or multiple graphics cards in SLI systems.
Before us is a printed circuit board in black with a classic arrangement of elements. In the central part is around the graphics processor is soldered memory chips. To the right is the power subsystem.
Note the absence of a protective frame around the GPU. This means that it is necessary to remove or install a cooling system extremely careful not to accidentally damage the chip.
The total memory capacity is dialed eight chips labeled K4G80325FB Samsung production. The power system consists of five phases, four of which are reserved for the GPU and one for memory. For power management using PWM controller uP9511P production uPI Semiconductor. As transistors used NTMFD4C85N production ON Semiconductor.
The used Intel Core i7-6700K, while the CPU frequency was rated as the CPU. The role of the platform served motherboard GIGABYTE GA-Z170X-Gaming 7. FCLK value was set by hand and in line with 1000 MHz. Memory functioned at the frequency of 3400 MHz XMP active profile with 16-18-18-36 timings.
Viewed instance is the reference: core frequency and memory corresponds to standard values, and is used for cooling the reference CO. Thermal interface for the GPU corresponds to the standard.
For the performance evaluation of synthetics used Valley Benchmark tests, Heaven Benchmark and 3DMark13.
Let us turn to gaming applications, and focus on the testing methodology. The measurement was conducted FPS with FRAPS utility. All games have been tested in the three most relevant resolutions: 1920×1080, 2560h1440 and 3840h2160. Manually disable the following options:
VSync (vertical sync)
All other settings, including smoothing, were installed at the maximum possible. For clarity, each game is provided with a screenshot with the graphics settings menu, only resolution is changed, all other parameters remained unchanged.
Based on the results, we can conclude that the 1070 GTX copes with most games at a resolution 2560h1440. If we turn to 4K, then this card is suitable only picky players who are able to compromise on and off in addition to smoothing parameters such as shadows, volumetric lighting or a range of drawing objects. Lack of FPS in this resolution is particularly noticeable on the example of such games as: Assassin’s Creed Syndicate, Crysis 3 and Metro Last Light.
To enhance the information content of the material here are a few videos taken on 3840h2160 resolution at maximum graphics, but with disabled anti-aliasing. Thus it will be possible to evaluate the influence of this parameter on the final value of the FPS. To view highly recommend to use the browser Google Chrome.
Testing took place in an open package at room temperature of 25 degrees. In idle mode, the GPU and memory frequency is reduced to 139/405 MHz, which directly affects the efficiency and improves thermal performance. In idle mode the temperature dropped to 37 ° C and under a load does not exceed 81 ° C. As for the noise level, at low loads the graphics card works if fairly quiet and hardly someone can not arrange for this parameter. Under load, the noise also does not come out of your comfort zone. In general, by reducing the power consumption and, as a consequence, reduce the heat – the reference cooling system copes quite confident with heat removal.
Acceleration was carried out using the latest version of the utility EVGA PrecisionX 16.
In addition to the standard menu with a change in the utility frequency and voltage settings available are three modes:
Basic – choose a point on the graph with a certain voltage value and specify the desired frequency level, thus there is a linear dependence of the building.
Linear – builds on two point that makes it possible to set the initial and final value, which affects the slope of the line.
Manual – set manually each frequency point for the corresponding value of the supply voltage.
In order to check the stability of the set parameters is recommended to use a built-in operating the scanner, whereby it checks the stability of the graphics card, depending on the frequency and voltage level. As a result, you can save a profile, where all the points on the graph will be marked.
The frequency of the graphics processor could increase by up to 215 MHz, which is the final version was 1721 MHz. However, given the GPU Boost desired value increased to 2100 MHz, which ensures a very substantial increase in productivity.
The memory frequency was increased to 655 MHz, and reached the value 2328 MHz (9.3 GHz QDR), it turned out great gain.
I suggest to get acquainted with the increased performance and Fire Strike Extreme Fire Strike Ultra:
NVIDIA GeForce GTX 1070 Founders Edition turned out successful in all respects. First of all, I note performance that allows you to play many games in 4K resolution, if you are willing to reduce some of the graphics settings. In addition to this, not to mention the relatively low consumption of video, which will help to avoid unnecessary costs in the supply unit. Everything else can be attributed, and a perfectly acceptable level of noise emitted by CO under load. But most of all pleased with the excellent overclocking potential, which ensures additional processing power and a significant increase in FPS games.
Should I buy Founders Edition or wait for the publication of the alternate versions? According to the author, rush to buy should not be. Let’s start with the fact that the options from NVIDIA partners will be provided with a semi-cooling system and will run much quieter. Another advantage in alternative embodiments piggy lower value is the maximum temperature under load and as a result, higher frequency values BOOST mode. Let’s not forget about the factory overclocking, which will have a noticeable impact on performance. Let us also remember about all sorts of design delights, such as RGB lighting, color scheme, and so on. The last argument for buyers may be the price. It is known that some models will be cheaper than the Founders Edition, that for all the previously mentioned advantages makes the purchase’s reference is almost pointless.
