The Radeon HD 7950 video card was launched on January 2012. This video card uses a graphic processor with 1792 stream processors that run at a speed of 800 MHz. The Radeon HD 7950 is equipped with 3072 MB GDDR5 memory. The memory transfer rate of this video card is 240 GB/s.
Performance And Power
The Radeon HD 7950 video card can deliver a computing power of up to 2867.2 GFLOPS of single precision computations. As per the video rendering performance, this graphic card can reach a pixel fill rate of 25.6 Gigapixels/s and a texture fill rate of 89.6 Gigatexels/s. When operating, the Radeon HD 7950 video card can consume a power of 200 W .
The Radeon HD 7950 uses a PCI-E 3.0 x 16 bus interface. More over, the Radeon HD 7950 supports up to Up to 6 displays monitors and can support the following display ports: "2 x Mini-DisplayPort, Dual-Link DVI, HDMI". The highest resolution supported by this graphic card is 2560 x 1600 using the DVI connector
The Radeon HD 7950 supports the following libraries: " DirectX 11.0, OpenCL 1.2, 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.
The AMD CrossFire technology is a technology developed by AMD, that let you harness the power of multiple GPU cards on the same computer. The Radeon HD 7950 uses a 4-way CrossFire, which let you connect up to four (4) graphic cards on the same computer.
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 7950 supports the following anti-aliasing techniques: 24 x MSAA, 24 x SSAA, Adaptive AA, MLAA 2.0.
AMD PowerTune ensures the processors operate within their limits by explicitly controlling the relationship between the power limit, operating temperature and the clock speeds. PowerTune manages the acceleration and deceleration of the GPU fan to control noise levels for a super quite environment.
AMD ZeroCore Power technology enables dramatic GPU power savings by lowering the power consumptions of all the GPUs in the AMD crossfire technology when the PC is idling. This technology increases the life span of the PC too.
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.
