The AMD Radeon HD 6870 graphic card was introduced into the market on October 2011. This video card is powered by 1120 processors each running at a clock speed of 900 MHz. The Radeon HD 6870 has a memory capacity of 1024 MB GDDR5. This graphic card memory has a bandwidth of up to 134.4 GB/s.
Performance And Power
The Radeon HD 6870 can produce a total computing power of 2016 GFLOPS. In addition, this graphic can reach a pixel fill rate of 28.8 Gigapixels/s and a texture fill rate of 50.4 Gigatexels/s. The Radeon HD 6870 graphic card consumes up to 151 W of power.
The Radeon HD 6870 video card is compatible with motherboards with PCI-E 2.1 x 16 support. In addition, this video card can support up to Up to 6 displays monitors and the display port supported by this video card are: "DisplayPort 1.2, Dual-Link DVI, HDMI, VGA".
The Radeon HD 6870 supports the following libraries: " DirectX 11.0, OpenCL 1.1, Shader Model 5.0 ". OpenGL is a cross language and multi-platform application programming interface for rendering 2D and 3D vector graphics. OpenGL is used to interact with a GPU to harness Hardware-accelerated rendering and eliminates the need to recompile shaders making it an efficient and performance oriented standard. Microsoft DirectX is an Application programming Interface for the Windows operating systems which Integrates well with AMD and NVIDIA GPUs. The Microsoft DirectX 10 is a significant step in 3D graphics. It features a highly optimized runtime, powerfull geometry sharders, and many other features. The Microsoft DirectX 11, introduced with Windows 7, brings numerous improvement over its precedessor DirectX 10. It is designed to be more efficient, supports sophisticated shading and texturing techniques and levearage the use of multi processors, resulting in smoother 3D animations. The open computing language (OpenCL) is programming interface used for general purpose programming across CPUs and GPUs and other processors. The standard gives developers the portability and efficiency of heterogeneous processing platforms.
With the AMD CrossFire technology technology it's possible to combine the computing power of multiple graphic cards on the same motherboard. The Radeon HD 6870 uses 2-way CrossFire, which let you connect up to two (2) graphic cards on the same motherboard.
Aliasing is a problem that can be observer in digital media such as image, videos, video games, and audio recording, In Video games, Aliasing can be observer through visual effects such flickering and as pixelated object edges. The Aliasing effects could be improved or suppressed by the use of Anti-Aliasing techniques. The Radeon HD 6870 supports the following anti-aliasing techniques: 24 x MSAA, 24 x SSAA, Adaptive AA, MLAA.
AMD HD3D technology
The AMD High Definition 3D technology enables 3D support for games, videos and movies in personal computers, and it provides a wide choice of solutions and support for hardware and software solutions. The AMD HD3D technology supports any type of screen however a frame ratio of 120Hz or more is recommended.
High Dynamic Range (HDR) Support
The high dynamic range (HDR) is used in imaging and photography to reproduce the great dynamic range of luminosity. HDR compensates for the loss of detail by taking multiple photographs at different exposure levels and then joining them producing a high total range photo or video.
HDCP, High Brandwidth Digital Content Protection
The NVIDIA high bandwidth digital content protection is designed to protect audio and video content being transferred from the NVIDIA GPU over DVI and HDMI cable to a display device. Both sending and receiving devices must be HDCP compliant.
