XFX Teases Radeon HD 7990 Triple Dissipation Graphics Card
XFX has introduced its own version of Radeon HD 7990 — a top-tier graphics adapter from AMD. As distinct from the other companies that incorporated only some inconspicuous changes into their products, XFX has approached to the card’s modification with a violent zeal. As a result, today everyone has a chance of examining its Radeon HD 7990 Triple Dissipation card that employs two Tahiti XT GPUs, elaborated on Graphics Core next architecture.
Each Tahiti XT chip comes with 2048 stream processors and 3 GB of GDDR5 memory. This implies that the total memory capacity makes up 6 GB. GPUs run at 950 MHz clock frequency, but have the potential of achieving 1000 MHz frequency on overclocking. As for the memory, it employs 384-bit bus and runs at an efficient 6 GHz frequency.
To continue, all the components of Radeon HD 7990 Triple Dissipation are housed on an original PCB, designed by XFX. Connection with the PSU is realized via a pair of 8-contact power sockets. The rear facet accommodates four mini-DisplayPort sockets and a single DVI port. The reverse side of the PCB is peculiar by the availability of a supplementary cooling fin.
The most unusual thing about this adapter is the implementation of an offbeat air-cooling system, called Triple Dissipation. It consists of an aluminum heatsink, eight copper heat-pipes and three large-scale fans that efficiently remove the heat.
The guarantee of the card’s functionality and performance is the support of a wide range of advanced technologies. Therefore, this model is compatible with DirectX 11.1 and ZeroCore Power, HD3D, Eyefinity, App Acceleration, PowerPlay, PowerTune, CrossFire from AMD.
