Radeon HD7970 is based on a brand-new GCN graphics architecture, with a transistor scale of more than 4.3 billion, and its total computing resources have increased to 2048 ALUs, while the Texture Fetch Load/Store Unit has increased to 512, and the Texture Filter Unit has increased from 96 in Cayman to 128, but at the same time, the ROP forming the back end remains the same as that in Cayman, with 32. HD7970 has a newly designed MC structure, and six dual-channel video memory controllers are combined to form a brand-new video memory control unit.
The features of HD7970 are composed of six main parts:
1. The new 28nm process of TSMC based on HKMG.
2. Front-end ACE( Asynchronous Compute Engine) including geometry engine, rasterization engine and first-level thread management mechanism.
3. There are 32 CU(Compute Unit) clusters that are responsible for processing computing tasks and Pixel Shader, including Texture Array that is responsible for processing materials and special computing tasks such as convolution and fast Fourier transform, secondary thread management mechanism and their corresponding shared+unified cache buffer systems.
4. ROP array, memory controller MC and PCI-Express3.0 bus transmission control terminal, which are responsible for completing the fillrate process and outputting the final picture.
5. UVD3.0 unit responsible for video playback and processing, and a brand-new VCE responsible for video coding.
6. Eyefinity 2.0 engine.

HD7970 locates the single-core flagship graphics card, and its arrival as scheduled once again makes AMD hold on to its traditional weapon-starting architecture. HD7970 not only has made great progress in DirectX 11 performance, small core area, but also has many new features including DirectX 11.1. Officially based on this feature, the performance of Radeon HD7970 graphics card completely exceeds that of HD6970/, and directly hits the dual-core product HD6990/GTX590.
The tough performance makes Radeon HD7970 graphics card become the benchmark product of a new generation of flagship installed products. How to install Radeon HD7970? The following is an analysis for you.
