SAPPHIRE RADEON HD 7970

"The Sapphire Radeon HD 7970 review also features the Sapphire Radeon HD 6970. The Sapphire Radeon HD 7970 uses the Tahiti GPU at 925Mhz and has 3GB GDDR5 memory running at 5500Mhz. The Sapphire Radeon HD 7970 has a 364Bit Memory Interface, 2048 Shader Processors and DirectX 11. We will be testing the Sapphire Radeon HD 7970 and Sapphire Radeon HD 6970 using Battlefield 3, Crysis 2, Dirt 3, Dragon Age II, Hard Reset, Modern Warfare 3, Elder Scrolls V and the Witcher 2 games for benchmarking. The powerful CPU we will be using is the advanced Intel Core i5 2500K."

Sapphire Radeon HD 7970

"The Sapphire Radeon HD 7970 is the first graphics card in the world to incorporate the latest generation of GPU's from AMD built in a new 28nm process and featuring the new GCN optimised graphics processing architecture. The HD 7970 is the most powerful single chip GPU ever built. It has a new internal structure with 32 compute units and a total of 2048 Stream processors. It ships with a core clock speed of 925MHz, and AMD Powertune technology allows enthusiasts to increase performance by overclocking. A new 384-bit high speed memory interface with over 264GB/sec memory bandwidth connects to a large 3GB array of the latest DDR5 memory."

SAPPHIRE RADEON HD 7970 FEATURES

8nm GCN (Graphic Core Next) Architecture

"The new and 28nm GCN Architecture with more efficient process technology puts more transistors in less space, enabling a dramatic increase in Processing Power. Crank the settings, devastate your enemies and bear witness to absurdly high frame rates with Sapphire Radeon HD 7970 graphics card-DirectX 11 has never looked this good. Maximum setting and crazy performance shouldn't be a compromise. The Sapphire Radeon HD 7970 with the new 28 nm GCN Architecture assures that it's not."

AMD HD3D Technology

"Enjoy the most immersive experience possible with full support for High Definition Stereoscopic 3D, a technique that presents 2D images (movies, games, photos) in a format that creates the illusion of three-dimensional depth when using compatible 3D displays / glasses / software."

PCI Express 3.0

"PCI-Express 3.0 delivers double the bandwidth per lane of PCIe Gen 2 for faster GPU (GPU communication-up to 16GB/sec in each direction), maximizing the performance from your GPU when paired with the latest platforms."

AMD Eyefinity 2.0

"The next generation of AMD Eyefinity technology is here, featuring all-new support for stereo 3D, universal bezel compensation and brand new display configurations. Face it: the best just got better: The enhancements for AMD Radeon HD7000 series include: Stereo 3D-multi-display stereoscopic 3D support via DisplayPort 16K X 16K maximum display group resolution-output up to 268 megapixels per GPU."

Efficient AMD CrossFire Technology

"Triple or quadruple gaming power with AMD CrossFireX Multi-GPU technology. Increase your gaming performance up to 2x with AMD CrossFire technology, 2.75x for TriFire configurations, or with QuadFire configurations. With AMD ZeroCore Power Technology, the graphics card in slave modes will be switched off in idle to maximize the power saving."

Discrete Digital Multi-Point Audio

"The Sapphire Radeon HD 7970 is the first GPU that can simultaneously output multiple and discrete audio streams via HDMI and DisplayPort Output."

Microsoft DirectX 11

"Get intense gaming performance and unrivalled image quality with stunning 3D visual effects, realistic lighting and lifelike imagery with SAPPHIRE graphics cards supporting DirectX11. New features in DirectX11 such as Hardware Tesselation, HDR Texture Compression, Multi-threading support and DirectCompute bring lifelike gaming and an experience never possible on a PC before."

Shader Model 5.0

"Supports the latest Shader Model 5.0 feature set including VTF (Vertex Texture Fetch) which is a key feature used extensively in many of the games that ship today. Without support for this feature the game will fall back to a lesser shader path resulting in the loss of cool, lifelike effects made possible by Shader Model 5.0."

OpenGL 4.2

"OpenGL 4.2 improves the GPU efficiency by improving the shader process operation and capturing GPU tessellated geometry. The process of modifying an arbitrary subset of compress texture is also simplified. The memory management in handling shaders is more efficient as well."

Best Microsoft DirectX11 Support

"The tessellation performance with the Sapphire Radeon HD 7970 is up to 2X faster than the previous generation, and DirectCompute performance is also faster to accelerate advanced post-processing, filtering, and anti-aliasing techniques. Direct X11 games has never looked this good."

AMD PowerTune Technology

"AMD PowerTune is a breakthrough technology that sets an entirely new direction for maximum performance at TDP. It allows the GPU to be designed with higher engine clock speeds which can be applied on the broad set of applications that have thermal headroom."
