Overview
Radeon HD 7970 GHz Edition is a High-End Graphics Card based on the First Revision of the Graphics Core Next (GCN) Architecture.

Architecture
The GCN 1.1 revision of the Graphics Core Next Architecture adds new important technologies and is largely oriented for energy efficiency. New technologies such as PowerTune and TrueAudio are the biggest additions as well as DirectX 11.2 support.

GPU
It equips a GPU Codenamed Tahiti XT2 which has 32 Compute Units activated and thus offers 2048 Shader Processing Units, 128 TMUs and 32 ROPs. The Central Unit is clocked at 1000MHz and goes up to 1050MHz, in Turbo Mode.

Memory
The GPU accesses a 3GB frame buffer of fast GDDR5, through a 384-bit memory interface. The size of the frame buffer is exaggerated and in no way benefits the GPU. The Memory Clock Operates at 1500MHz.

Power Consumption
With a rated board TDP of 275W, it requires at least a 600W PSU with one available 6-pin and one available 8-pin connectors.

Performance
Radeon HD 7970 GHz Edition competes with GeForce GTX 680 and is essentially a Higher Clocked Radeon HD 7970 with the addition of The Boost Clock.
It proves to be faster than GeForce GTX 680 at resolutions up to 1920x1080 but takes further lead beyond that.

System Suggestions
Radeon HD 7970 GHz Edition is best suited for resolutions up to and including 1920x1080. We recommend a Very Strong Processor (Intel Core i7 Quad Core/AMD FX Eight Core) and 8GB of RAM for Optimal Performance.
