EVGA GeForce GTX 1080 SC Gaming ACX 3.0 vs GIGABYTE GeForce GTX 1080 Xtreme Gaming Premium Pack

The EVGA GTX 1080 ACX 3.0 uses its own built-in cooling system which includes two fans. The ACX 3.0 cooler has been used on a lot of high-end graphics cards, and the GTX 1080 by EVGA is no different. In an idle situation, the EVGA GTX 1080 generally reaches temperatures up to 56° Celsius. At a first glance, that's pretty high, but the fans don't start spinning unless a temperature of 60° is reached. During full load, the EVGA GTX 1080 chip heats up to a maximum of 75 degrees Celsius - eight degrees cooler than a reference (Founders Edition) GTX 1080.

The maximum temperature of 75° C also means that throttling doesn't occur with the EVGA GTX 1080 SC Gaming ACX 3.0, something that tends to occur with other GTX 1080 cards with worse coolers. In other words, the graphics card won't slow itself down in order to stay cool: performance will be 100% at all times.

The GTX 1080 SC Gaming ACX 3.0 is a virtually silent card. In a non-gaming idle situation, the two fans of the cooler don't spin up at all - the card stays completely inaudible up to temperatures of 60° Celsius. Even during full load and intensive gaming situations, this edition of the GTX 1080 is remarkably quiet and stays under 40 decibels (when measured two inches above the motherboard in an open environment). For comparison: the reference GTX 1080 produces 45.5 dB of noise. Annoying coil whine sounds are not present in this edition either.

The GTX 1080 SC Gaming ACX 3.0 features a higher clockspeed compared to a reference GTX 1080, which means it has been factory overclocked to reach higher framerates and overall better performance. The base clock speed has been set at 1708 MHz, which is a 6.3% increase compared to the reference 1607 MHz. The boost clock has also received a factory overclock to 1847 MHz compared to the standard 1733 MHz, a difference of 6.5%.

This results in a slightly better performance, although practical performance differences aren't as noticeable. For example: In Rise of the Tomb Raider at 1080p and maximum settings, the SC ACX 3.0 is nearly 5 FPS faster than a regular GTX 1080. In the benchmarking suite 3D Mark Fire Strike Extreme, a GTX 1080 with reference clock speeds achieves a score of 9,387 points while the EVGA Superclocked takes the crown at 9,622 points. Although the performance differences between this overclocked card and a reference GTX 1080 are minimal, the extra power is nice to have nonetheless.

The EVGA offers the most performance for the dollar, and is $100 cheaper than almost any other decent GTX 1080 card. It has a great cooler, and comes with a decent clock speed without compromising the noise the card makes making it a well balanced option.

As it only requires 1 8 pin connector, it draws much less power for those whom may not have a high wattage rating power supply. Making this more eco friendly when it comes to energy usage.

The extensive cooling solution of the Xtreme Gaming GTX 1080 results in a very quiet operation. In idle situations, the cooling fans don't spin up which means the graphics card doesn't produce more noise than any other component in your system. Under full load, a sound production of 38 dBA was measured, which is considered to be very quiet by graphics card standards. For comparison: The reference Founders Edition of the GTX 1080 produces 49.4 decibels (A) under load. Decibels use a logarithmic scale, which means the Xtreme Gaming card is effectively two times as quiet as a reference GTX 1080.

The exterior of the Gigabyte GTX 1080 Xtreme Gaming features a lot of RGB lights and you can adjust the color of these lights via Gigabyte's included software package. This allows you to customize the look of the graphics card, which can be useful if your setup is built with a specific color scheme in mind.

Gigabyte is offering an extended Xtreme Care warranty period of 4 years, which is a major improvement compared to the regular 1-year warranty on graphics card. In the event of a failure within this period, Gigabyte will repair the card or send you a replacement model. Online registration is required.

The GTX 1080 Xtreme Gaming cards are especially suitable for virtual reality headsets such as the Oculus Rift or the HTC Vive, which require two HDMI-ports. Included in the packaging is a 5.25" extension bay, with two USB 3.0 ports and a set of HDMI inputs. With this frontpanel, users are no longer required to route their VR headset through the back of the system. The graphics card itself features two HDMI-ports on the opposite site of the usual ports, which allows a quick pass-through to this frontpanel. When using these two specific HDMI ports, two of the three DisplayPort inputs are disabled.

The GTX 1080 Xtreme Gaming reaches a maximum temperature of 66 degrees Celsius under load with the increased clock and memory speeds. This is a major improvement over the Founders Edition's 82° C and an impressive feat for an air cooler. This not only extends the longevity of the card, but also prevents throttling from happening. Throttling can occur when temperatures reach around 80° C or higher. This is when the graphics card will slow itself down (reduce clock speed) in order to stay cool, effectively sacrificing performance. With the default clock speeds, this should never occur with the Xtreme Gaming card.

The higher clock and memory speeds of GIGABYTE's Xtreme Gaming edition of the GTX 1080 results in better performance. In Battlefield 4 using 1440p resolution and maximum settings, an average framerate of 118 was achieved. For comparison, a GTX 1080 Founders Edition only managed to achieve 110 fps, an almost 7% difference. Similar results can be seen in Far Cry Primal, again with 1440p resolution and maximum settings. The Xtreme Gaming card manages to get 84 frames per second on average, compared to the Founders Edition's 78 FPS. In DOOM, the difference is even more noticeable. With maximum settings and 1440p resolution, an average FPS of 140 was achieved for the Xtreme Gaming card - a 15 FPS improvement over the reference card. When tested in 4K, the Xtreme Gaming managed to achieve 72 average FPS compared to the Founders Edition's 62 frames per second, a difference of almost 14%.
