It is a huge card that takes up a whopping four PCI slots. The GTX 1080 Kudan uses a custom-PCB with dual 8-pin PCie power connectors and the front features large heatsinks that are cooled by three large fans. The backplate consists of plexi waterblock, which may be detachable.
The cooler itself is equipped with three fans surrounded by gold cog-shaped rings. The I/O bracket has special OC-button to switch between the BIOSes (quite possibly for air and water-cooling).The card has a 1936MHz Boost clock, on par with the ASUS STRIX and Gigabyte Xtreme models, but slower than the 1961MHz GALAX HOF model. Availability is slated for December or January, but as mentioned above this is primarily for the Chinese market.
