The laboratory continues the series of materials dedicated to the GeForce GTX 1080. We have examined several versions from different manufacturers.
Line EVGA SC Gaming involves the use of a reference PCB and reference cooling system, which ultimately provides a balanced graphics card. Models in this series offer high quality, optimized performance and additional opportunities for corporate improvements. So EVGA GeForce GTX 1080 SC Gaming is a great solution for gamers.
It should be noted that from me personally this is the last material on the test methodology. Besides the fact that it will be substantially revised and expanded, the new tests and benchmarks. And in the future, the transition to the new test stand with which to buy more equipment and certain optimization settings. This is done to improve the quality of the output material and the growth of positive ratings.
Full name: EVGA GeForce GTX 1080 SC Gaming ACX 3.0, manufacturer code: 08G-P4-6183-KR.
The EVGA model comes in a small shiny package, protected with a plastic coating. On the front side emphasized large inscription declared overclock (and also the name of the line) and specify the amount of RAM (8 GB standard GDDR5X). In addition, mention the model name and supported technologies, including VR Ready.
On the back there is typical for this manufacturer transparent window through which is visible a portion of the fee and “backplate” with an identifying sticker with the serial number. Quick description decorated in the form of a list of supported functions in five different languages.
The graphics card is placed in the form of bottle of plastic filled with loose items supplied. The company EVGA is a special moment.
Bundle accessories includes CD with drivers, user manual, brochure, couple of stickers, a power adapter 2 x 6 pin -> 8 pin.
Gamers will care about the big poster on the wall. Cartoon knight grips the sword from the ACX cooler and ready to fight.
EVGA GeForce GTX 1080 SC Gaming got the interesting design of the casing, which transformed coloring. White-black casing of system of cooling together with the metal inserts, lattice coverings and emblems identifies a product from other manufacturers in a dark wash.
The front panel comes with two fans with a diameter of 90 mm with an interesting curved shape of the blades. They practically cover the entire radiator height, which has a positive impact on the efficiency of the cooler. This approach is advantageous of the three decks of a smaller size.
Modification “08G-P4-6183” has “backplate”, which strengthens the structure and protects it from bending. Besides, it protects the PCB from foreign objects. On its surface are provided slots for hot air outlet located in the hot zones of the graphics card.
The rear panel is exactly the same as the reference version of Nvidia, and here we can mention five outputs:
The following resolutions are supported:
Supplementary feeding is implemented by a single eight-pin connector. It covers all the expenses of graphics and features, along with PCI-Express package TDP of 225 watts, which is quite enough for overclocking. For convenience, the casing of the cooling system took a little to the side, opening access to the latch.
We add that the novelty has received the illuminated logo of the manufacturer and the name of the GeForce GTX 1080.
Length EVGA GeForce GTX 1080 SC Gaming comparable to the reference model and is 267 mm, but the width due to side panels with illumination equal to 112 mm. In the PC video card will block two expansion slots.
Cooling system ACX 3.0 made in traditional design and is fixed with four screws in the field of graphic processor. Two short wiring from fans and lighting complicate the disassembly.
The thermal interface used grey paste, which caused more abundantly. The base is treated with small circular cutter, felt the roughness of the surface, polishing is missing.
The test line showed no deformation of the reason that can be attributed to the pluses.
Instead of a separate radiator is used massive plate, somewhat reminiscent of the “backplate”. It is devoid of the fins, which reduces the effective area of dispersion, however, covers all the elements and is in contact with them via thermal pads.
For active part responsible for two fans, which are hidden by a plastic casing with metal inserts. Underneath reveals the four boards responsible for area lighting.
The fans are manufactured by Power Logic, model PLA09215B12H. Features – 12 V and 0.55 A. They work in the range 0-3000 rpm while remaining very quiet 1200 rpm and quiet up to 1600 rpm. Excellent performance!
The reverse side is hidden behind the base plate. “Backplate” only comes in contact with the area of the graphic processor: if developers used another thermal pad on the site of the power subsystem, the EVGA GeForce GTX 1080 SC Gaming would be an example for others to follow.
Video card EVGA GeForce GTX 1080 SC Gaming built on the reference PCB GeForce GTX 1080.
Many manufacturers produce models on the reference PCB, thus simplifying the task of producing new products. From the positive side the unification, the ability to install “Polivanov” and third-party systems.
The power subsystem is built according to the scheme “5+1”, where five phases are assigned to the GPU and one for memory. On the PCB there is a place for one more phase, but its developers to unsolder did not.
As the PWM controller chip is used uP9511P production uPI Semiconductor.
The heart of a hero review is the GPU GP104-400-A1, produced on 16 nm process technology at the 16th week of 2016. It includes 2560 shaders, 64 ROPS and 160 texture units.
Video card is equipped with eight gigabytes of memory, which recruited eight Micron chips production standard GDDR5X. Clock frequency of the memory chips amounts to 1251 MHz (effective frequency – 010 10 MHz).
Testing EVGA GeForce GTX 1080 SC Gaming took place in the following configurations:
For overclocking graphics cards, as well as monitoring temperatures and fan speed were used proprietary utility MSI Afterburner v4.3.0 Beta 14.
Check the stability of the accelerators in the process of dispersal was carried out by 3.5 utility MSI Kombustor (GPU Burn-in, 1920 x 1080). The received frequency was further tested by the runs test Heaven Benchmark 4.0 c v extreme levels of tessellation and GPU tests from the packages 3DMark 2013, 3DMark 11 and 3DMark Vantage.
To check the temperature of GPU in conditions close to daily, I used Heaven BenchMark v4.0 (quality: ultra, tessellation: extreme, AA8x, 1920 x 1080).
The noise level was measured using a digital sound level meter TM-102 with a measurement error no more than 0.5 dBA. The measurements were carried out with a distance of 0.3 m. the Level of background noise in the room – no more than 28 dBA. All system fans including installed in the power supply was turned off. On the charts of the conventional low noise for the system is defined at the level of 30.5 dBA, the conventional comfort – 37 dBA. The temperature of the air in the room was 25 degrees Celsius.
Additionally starred readings of power consumption using the power meter Robiton PM-2 and the temperature of the PCB infrared thermometer Fluke 59 MAX
EVGA GeForce GTX 1080 SC Gaming is different from the reference version is not only cooling, but with increased clock frequencies. The developers raised the bar for the performance of their models by a few points. The core frequency is now 1709 MHz, in Boost mode – 1848 MHz in games that dynamically rises to 2000 MHz at 1.062 V. Memory operates at a reference value.
Cooling system ACX for the second series left a good impression, but her older version is not inferior in anything. In idle mode the fans stop and the video card is completely silent: spurious sounds from the power subsystem is not marked. The temperature is kept at around 35-36°C.
In the test, Heaven Benchmark 4.0 the following can be observed: the frequency of the graphics core immediately up to 2000 MHz and is retained on this bar to achieve a temperature of 46°C, followed by step-by-step decline until 1911 MHz at a voltage 1.031 V and the fan speed only 1068 rpm.
The balance in favor of low noise impact on the GPU temperature, which rises to 75°C. But to avoid third-party sounds fails: chokes emit spurious sounds. In a closed PC almost do not notice them, but on the open stand has to be tolerated.
EVGA GeForce GTX 1080 SC Gaming trapped in the framework of energy consumption, which reflects the stress test. Activation of protective mechanisms impact on the General background novelty: the core frequency drops to 1695 MHz at 0.875 V. by the Way, great architecture, allows you to run the GPU at such voltage and frequency.
Cooling system being left on her own and worked full-time, temperature GPU barely reached 74°C.
The crackdown was conducted with the fan speed is 100% (3000 rpm). Even increased to 120% Power Limit is not allowed to overcome the bar frequency in 1789 MHz 1401 MHz for core and memory respectively. In games, the GPU frequency is dynamically increased to 2114 MHz.
Here is a graph of the temperature of the graphics core and system power and fan speed of the cooling system. This card is devoid of sensors in the field of power supply circuits, therefore, the results of the power section were obtained using a pyrometer.
The main purpose of the cooling system ACX 3.0 – comfort. One can understand the producer, because how many people care about the temperature of the power phases? My recommendations would be as follows: to raise the rotation speed of at least 1400 rpm and provide a cooler, productive and grateful graphics card .
Graph the power consumption of the whole stand depending on the frequencies of video cards and operating voltage of the GPU.
Power consumption in 2D was measured at idle (on the desktop). Testing in Heaven BenchMark 4.0 was conducted under the following settings – quality: ultra, tessellation: extreme, AA8x, 1920 x 1080 resolution; MSI Kombustor – 2xMSAA, 1920 x 1080.
In my opinion, EVGA GeForce GTX 1080 SC Gaming is a very balanced solution among all the GeForce GTX 1080. And one reason for this is that the developers have lowered the speed of fan impellers to an optimal minimum, making the card silent. However, this affects the overall temperature.
Among other advantages of the new note factory overclocking, advanced package and three-year warranty. Let the first is no surprise (especially on Nvidia models), but the console Superclocked here for a reason – a guaranteed performance increase provided.
The manufacturer have positioned their model as the optimal solution for gamers, which is the top in the line of SC Gaming. Want something more? Then you need a graphics card from the family of FTW – For The Win!
