Hand in hand with its launch of AMD 7000 series of graphics cards, XFX introduced the Ghost cooler. It comes in two flavors – single and double fan versions. The latter is called Double Dissipation (DD) and is the one used on our sample. The version with two fans is quieter and offers more headroom for overclocking. All the coolers used by XFX on HD 7900/7800/7700 series are two slots wide, regardless of whether they have a single fan or two fans.

The Black DD R7790's cooler comes with a nice aluminum frame and the two fans will ensure stable operation of the overclocked GPU. The card uses an IP5X Dust Free fan and XFX Bracket Design.

The PCB is in-house designed and built and features quality Duratec professional grade power components.

The cooler uses a large copper plate which is connected to the heatsink, although the memory is cooled only by air. XFX used GDDR5 chips made by Hynix (model number H5GQ2H24AFR R0C). These chips are specified to run at 1500 MHz (6000 MHz GDDR5 effective), but XFX factory overclocked them to 6400MHz. On the back side are four of eight memory ICs.
