They Asia region based Expreview did some simple and quick testing with a GeForce GTX 1070. By itself not news, but this one is the single slot version GALAX GTX 1070.
The card is just funky to look at, however single slot solutions often do not have the capacity to cool down the card sufficiently, and when they do they are often very loud. The product is tagged under Katana, katana is characterized by its distinctive appearance: a curved, single-edged blade with a circular or squared guard and long grip to accommodate two hands.
Expreview conveniently did not mention noise levels but they even tweaked the card a little and reached 1519 MHz on the base clock frequency.
