The twin chips are clocked at 1000 MHz, and PowerColor gives each of the pixel-pushers 8GB of RAM running at 1350 MT/s. Since one R9 390 is toasty enough on its own, it's clear that more extreme measures would be needed to make a dual-GPU setup work. To that end, PowerColor uses three "double blade" fans, sitting atop a grand total of ten heat pipes and heaven knows how many cooling fins.
Feeding the kind of raw power those chips need isn't easy, either, so builders will need four 8-pin PCIe power connectors. Perhaps there's finally a use for that 1 kW power supply in the parts closet, eh? The card distributes all those electrons through 15 power phases, and the Devil 13 logo's LED backlight pulses to let you know it's watching. As an extra temptation, PowerColor offers a Razer Ouroboros mouse in the box.
There's no word on a release date or a price, but given the dual-GPU setup and extra goodies, the Devil 13 seems likely to sink your credit card lower than the seventh circle.
