Introduction

The previously reviewed Gigabyte cards G1 Gaming GTX 980 and 980 Ti made a good impression the same way Zotac did. Both cards used an effective cooling system. At the time, Gigabyte maintained its card within the two-slot form factor and also used an all-copper plate for the core and VRAMs. The Gigabyte G1 Gaming GTX 1080 uses the brand new GP104 Pascal architecture with the custom cooling and PCB design, along with factory overclock profiles. As you will expect, all of Nvidia AIC partners have okay-to-good-to-best designed cards.

Keep in mind that Gigabyte and MSI mention its boost clock first and then its base clock.

Gigabyte G1 Gaming GTX 1080 has two profiles- the by-default enabled gaming profile that provides an additional 86MHz and OC profile with 115MHz bump over the reference’s base clock. The card is a dual slot card with triple fan cooling setup. For those who are interested, you can read up on the Nvidia GeForce GTX 1080 Founders Edition review.

Packaging

Gigabyte’s G1 Gaming packaging is pretty standard which advertises three of its selling points- the Windforce cooling, GPU Gauntlet and the RGB spectrum colour lighting. While Gigabyte did point out its output options, they haven’t mentioned its clock speed on the box. But there is a QR code so people who are making the last minute no research purchase can get their hands on basic information. G1 Gaming’s accessory box is big, but it comes with a manual and a disc.

No case badge. no added accessories. This accessory box is a troll.

Profile presets

The difference is that Zotac typically sets a single out-of-the-box factory overclock. Gigabyte and MSI include two profiles- gaming and OC mode. The only way to select the product is to use its proprietary software. During the Asus/MSI clock gate controversy, people asked why couldn’t companies have the highest overclocked profiles enabled by default for everyone. It’s a valid question as switching between the profiles knowing that OC profiles provide a higher factory clocks seems redundant.

When I asked if using the OC profile all the time would affect the longevity of the core. They replied:

No, this was not our consideration when we offered 2 modes. It’s purely to offer a good user experience.

The following is the difference between the overclocked profiles:

Reference Zotac AMP! EXT. Gigabyte G1 (Gaming) Gigabyte G1 (OC)
Base 1607 1696 (+89) 1722 (+115)
Boost 1734 1835 (+101) 1860 (+126)

Gigabyte should consider a single factory overclocked profile with the maximum possible setting. The VGA maker brags about its GPU gauntlet which means they use the best ASIC quality chip for this series. That’s all the more reason they can have the highest factory overclock out-of-the-box.

Let’s check out the performance this card offers, and its cooling + manual overclocking potential!

G1 Gaming GTX 1080 Design

The first impression- this card is incredibly light. It makes an impression that it is lighter than the Founders Edition, its GTX 980 and GTX 980Ti G1 Gaming cards. Gigabyte reduced the weight by having copper base reserved only for its GPU core and reducing from six to three 6mm copper heat pipes. The only LED on this graphic card is the logo and its fan stop indicator. The GPU shroud is a bit longer than its PCB, which shows three copper heat pipes.

The Gigabyte G1 Gaming GTX 1080 takes additional power from an 8 pin PCIe connector. The card also has an LED indicator which lights up solid if the PCIe power cable is disconnected and blinks if there is any abnormal power flow. If its all good, it will be off.

The GPU shroud is plastic while its backplate is metal. The only design is the orange highlights on its shroud. The design doesn’t really stand out like MSI and Zotac’s variant. Some people may light the limited LED presence with a down-to-Earth design. Some may not. This is more of a preference.

Gigabyte G1 Gaming GTX 1080 uses the same outputs like its Founders Edition. But the key difference is that all of its DisplayPorts are brought in together while its HDMI port is kept towards the end.

Comparison with the Founders Edition

The width of the graphic cards is the same, with a difference in its length. Obviously, the cooling system is the highlight of the G1 Gaming.

I did not take the images of the inner area since I ended up fixing the thermal pads on the chokes. While its VRAMs used thicker thermal pads, the chokes used very thin pads, enough that it was torn and misaligned from the inside at the time it was removed. While the previous G1 Gaming units had contact between the VRMs and the main heatsink’s surface, it was all copper. Not in this case. You’ll need to remove all the seven screws over its back plate.


Gigabyte G1 Gaming GTX 1080’s product page included Xtreme Gaming’s OC utility. Apart from its skin, there shouldn’t be any differences in its function. The utility can be used for manual overclocking, saving OC and fan profiles & customizing the lighting options.

Tab options

There are three clock profiles: ‘Eco’ ,’Gaming’ and ‘OC’. As said earlier, Gaming profile is enabled by default. The Eco mode reduces its base clock down to 1607MHz. While its base clock is the same as its Founders Edition, the eco mode’s boost clock is up to 1746MHz. Also, there are three fan profiles with manual setting options and LED settings with six presets.

audio flashing

This is the first time I’ve seen ‘audio flashing’ LED light effect on a graphic card. But to be fair Gigabyte motherboards did have this function.

With other GPU overclocking utilities, they have a separate function for “apply” and saving/loading the profiles. But the Xtreme Gaming utility overwrites the currently selected profile once a new manual setting is applied. This is not a good idea as you one may lose the previous stable overclocking setting while experimenting with more overclocks. The only workaround is to load another profile and then overclock further. Gigabyte should have the manual profile save button and not let the utility overwrite the new and untested overclock settings.

ASIC Quality

ASIC

This review unit reflects 92.8% ASIC quality, the highest I’ve seen till date. Higher the ASIC quality, lower its power consumption and better overclocking potential. It’s OC profile provides 115MHz over its FE spec’s base clock.

Overclock attempts

The first attempt was a +135MHz increase and 19% increase in its GPU voltage. The only time this setting crashed was with Fire Strike Ultra’s GPU Test 2 run. It did generate GPU Test 2 score. I’ve reduced it down to +120MHz with +35% GPU voltage and it worked.

Reference Gigabyte G1 (Gaming) Gigabyte G1 (OC) Gigabyte G1 (Manual OC)
Base 1607 1696 (+89) 1722 (+115) 1816 (+209)
Boost 1734 1835 (+101) 1860 (+126) 1955 (+221)

Compared to Founders’ Edition base clock, that’s a 209MHz. This chip allowed 94MHz bump in base clock over the OC profile’s base clock. That’s pretty good seeing that its OC profile already provides a +115MHz increase compared to FE’s base clock. The manual overclock’s boost goes up to 1955 MHz.

With Fire Strike Ultra running in its background and fan manually set on auto:

Manual OC GPUZ LOAD

Within 50% fan speed, the overclocked card manages to stay cool at 68 degrees Celsius. Even with the reduced material and heatpipe count, the cooling system is doing a good job with the additional 94 MHz increase over the overclock preset profile.

With the same settings, the following performance boost is achieved.

Test Setup

Hardware BBQ gets very minimum support from hardware manufacturers since we have a no-strings-attached policy and ended up blacklisting even tier 1 brands for improper misconduct. But thanks to a handful of companies who value the importance and benefits of providing components for the test bench, we do what we’re good at with the resources at hand. I would like to thank:

  • Gigabyte India for providing Gigabyte Z97X-Gaming GT Rev 1.0 motherboard
  • WD India for providing 4x WD Red 3TB NAS drives
  • Coolermaster India for providing Coolermaster GX450 RS-450-ACAA-D3 Power Supply
Test Setup for: Gigabyte G1 Gaming GTX 1080
CPU+ CPU Cooler Intel i7 4790K + Noctua NH-U12S
Motherboard Gigabyte Z97X-Gaming GT Motherboard
Memory Kingston 8GB 1600MHz DDRIII
Primary OS drive SanDisk Extreme 240GB SSD + WD Red 3TB WD30EFRX
Power Supply Corsair TX750

LuxMark

LuxMark is a OpenCL cross-platform benchmark tool. The idea for the program was conceived in 2009 by Jean-Francois ‘Jromang’ Romang. It was intended as a promotional tool for LuxRender (to quote original Jromang’s words: “LuxRender propaganda with OpenCL”). The idea was quite simple, wrap SLG inside an easy to use graphical user interface and use it as a benchmark for OpenCL.

In the end…

I was concerned that this lightweight card would mean lesser cooling effectiveness. Its good to see that this isn’t the case with the G1 Gaming GTX 1080 card. The only part that I would wish Gigabyte to correct is to start having a single (and highest) factory overclock out-of-the-box cards. I also do wish that its XG utility does not override the selected profile once newer manual overclocks are selected.

The only LED function this graphic card has is its logo. Not a dealbreaker unless you are looking to match your components with a particular colour combination or they just want RGB disco in their system. The main issue is that while Gigabyte G1 Gaming GTX 1080 isn’t a bad card, but other variants including its own Xtreme Gaming lineup would overshadow this card easily.

The fans do not generate an audible sound in a closed case setup up to 75% fan speed, assuming you will require that much fan speed. Having a thin thermal pad on the chokes isn’t the good idea. If a user needs to change the thermal paste on the core in the distant future, that will tear easily and probably make it unusable.

Investing in a Gigabyte G1 Gaming GTX 1080 over its founder’s edition could be a pricey affair. This depends on which country you’re in and/or the dealer’s price gouging factor (if present).

But if you look at other company’s offerings, Zotac offers its 1771 MHz base clock AMP! Extreme card for $869.99 and 1708 base clock (OC Profile) MSI Gaming X for $829.94. Gigabyte’s OC profile’s base clock is 1721 MHz (OC preset). Gigabyte is providing a pretty good deal on this card for the moment in the US. Keeping all this in mind, this card provides a good value.

  • Effective cooling system
  • Minimum LED bling
  • GPU Gauntlet
  • Light Weight
  • Minimum LED bling
  • Thin thermal pad on the VRMs
  • XG OC Utility overwrites selected profile when clock/fan speed is increased
