The volume of GDDR5 memory is 3 GB and a bus uses 384-bit. New frequency formula is as follows: 925/5500 MHz (core / memory), but thanks to the good overclocking potential GPU easily able to operate at 1 GHz and higher.
The support for an interface, PCI Express 3.0, as well as proprietary technology AMD ZeroCore Power, by which power the video card at idle is less than 3 watts, while maximum power consumption may reach 210 W.
