GIGABYTE has outed their GeForce GTX 1080 Mini ITX 8G, the newest entrant in the high-performing small form factor graphics space. At only 169mm (6.7in) long, the company’s diminutive offering is now the second mITX NVIDIA GeForce GTX 1080 card, with the first being the ZOTAC GTX 1080 Mini, announced last December. While the ZOTAC card was described as “the world’s smallest GeForce GTX 1080,” the GIGABYTE GTX 1080 Mini ITX comes in ~40mm shorter, courtesy of its single-fan configuration.

Just fitting in the 17 x 17cm mITX specifications, the GIGABYTE 1080 Mini ITX features a semi-passive 90mm fan (turning off under certain loads/temperatures), triple heat pipe cooling solution, and 5+2 power phases. Despite the size, the card maintains reference clocks under Gaming Mode, with OC Mode pushing the core clocks by a modest ~2%. Powering it all is an 8pin power connector on the top of the card.

The dimensions of the GIGABYTE GTX 1080 Mini ITX actually match GIGABYTE’s previous GTX 1070 Mini ITX and 1060 Mini ITX cards, as well as their OC variants. This is in line with mid-range and high-end mITX cards generally bottoming out at ~170mm lengthwise to match the mITX form factor specification, with the exception of the petite 152mm Radeon R9 Nano, a card made even smaller due to the space-saving nature of HBM. This is a non-trivial distinction, as graphics card dimension measurements often do not include the additional length of the PCIe bracket and sometimes delineate length of the PCB rather than the cooling shroud. In any case, the 211mm long ZOTAC GTX 1080 Mini actually extends over mITX motherboards. For SFF enthusiasts, these millimeters matter.

In the meantime, the GIGABYTE GTX 1080 Mini ITX will be the fastest 169mm long card. For the competition, with the R9 Nano no longer in production, the Vega-based Nano has only been teased at SIGGRAPH 2017 so far.

Details on pricing and availability have not been announced at this time.

    Really interested in the noise levels. Reply

    I have two of the GTX 1070 Mini ITX 8G cards that look just like this. Honestly I don't hear them under an EK Predator 240mm with Vardar fans. They just aren't noisy.

    I came from a watercooled build with 8x gentle typhoon 1850rpm fans at somewhere like 1200rpm.

    Too bad it isn't a blower of some sort. Blowers are basically required in a small ITX case. However, I understand the technical hurdles of making a blower on such a short card. But they could still do it by making the cooling shroud thicker. Reply

    You have a good point. The 1070 cards are blowers. This card seems to have gotten rid of that in favor of the extra DVI port. Reply

    I've always wondered why people say this.

    I've always put normal dual-fan GPUs in my ITX cases and never had any problem with heat. They are quieter than the blower fans too which is why I still choose them.

    You really won't need to care with the 1070 cards, they just never get noisy. Vardar fans are worse. I don't know the noise level of the 1080 versions. Reply

    The Zotac 1080 ti mini has 45 percent minimum fan speeds, and I imagine the Zotac 1080 version is also bad.

    Here's to hoping that the Gigabyte one is actually quite while web browsing.

    "the GIGABYTE 1080 Mini ITX features a semi-passive 90mm fan (turning off under certain loads/temperatures)"

    so it's 0db when browsing

    My RX380 actually stays completely off in just about anything BUT games. It waits to hit 60c before turning on. It takes a semi-heavy, prolonged load to reach 60c even in my tiny case. For example, some games like Warcraft III don't even seem to use 3D (the card temps barely increase from idle) and various other light-weight games like Axiom Verge take about 20 minutes to get the card to wake up the fans.
