Based on AMD's well known Hawaii GPU (now called Grenada) with 2816 Stream Processors, which is pretty much the GPU that was behind theRadeon R9 290X, the new Powercolor Devil R9 390X also packs 8GB of GDDR5 memory paired up with a 512-bit memory interface and comes with a fully custom desing with 8-phase VRM, custom cooling and high factory-overclock.
The Powercolor Devil R9 390X works at 1100MHz for the GPU while 8GB of GDDR5 memory ended up clocked at 1525MHz (6100MHz effective).
The new Powercolor Devil R9 390X is also the only Radeon R9 390X graphics card that packs the Hybrid Cooling System, or a combination of a dual-slot air cooler and liquid cooling system. The Smart Air Cooling system, as Powercolor calls it, cools the VRM part of the graphics card while the liquid cooling system is probably taking care of the GPU and RAM.
According to our sources, the Powercolor Devil R9 390X should be priced at around €479 in Europe, which is a small price premium over the standard R9 390X. Unfortunately, we still do not know when it will hit retail/e-tail shelves.
