GALAX is marketing the KATANA as the world's first single-slot GTX 1070 single-slot graphics card with a maximum thickness at just 16 mm, which is an engineering feat in itself. The card leverages a "legendary turbo radiator" (it's funny how the renders show a white warning sign next to the cooling fan with a "CAUTION Hot Surface" warning, though that's probably needed there to avoid any lawsuits from burns resulting from touching the card while gaming.)

The card features a RazorX cooling technique, with copper fins and a vapor chamber that "maintain cooling performance even in thermally challenging scenario(s)". The GALAX GTX 1070 KATANA uses a single 8-pin connector, and video output is taken care of by 1x DisplayPort 1.4, 1x HDMI 2.0b, and a single DL-DVI-D connector. Clocks on the card are reported at 1518 MHz base, and 1708 MHz boost clocks. I wince at the noise and heat this baby must put out, and wonder how much it's going to be thermally throttled, but I guess those are necessary drawbacks for what is otherwise an interesting single-slot design.
