Powercolor releases the Devil 13 Dual Core R9 390, a video card equipped with two Grenada GPUs at 1000Mhz. The difference with the Radeon R9 295X2 is that Powercolor cools the Devil 13 with air and provides it with 16GB of memory.
AMD’s last dual GPU card is the Radeon R9 295X2, which was released in April 2014. However, Powercolor is now announcing its own build that resembles the R9 295X in specifications, but does not have water cooling.
The Devil 13 Dual Core R9 390 contains two Grenada GPUs that run at 1000MHz. That is slightly less than the R9 295X and the R9 390X. PowerColor does not specify whether these are Grenada Pro GPUs with 2560 stream processors, or XT GPUs with 2816 stream processors each. The memory speed of the gddr5 memory is 5.4GHz, which is slightly higher than with the 295X2. In addition, there is twice as much memory available; twice 8GB instead of twice 4GB. The memory communicates with the GPU via two 512-bit wide memory interfaces.
Three double blade fans have to keep the GPUs at the right temperature and ten heat pipes dissipate the heat. The card draws power from a 15-phase power supply and must be connected to the power supply with four 8-pin PCI-E plugs. According to Powercolor, a system that can handle the card must have at least a 1000W power supply.
When exactly the Devil 13 will be available and what the video card should cost is not yet known.
