The AMD Radeon R9 280 graphic card was released on March 2014. This video card features a graphic processing unit stacked with 1792 stream processors running at a clock speed of 827 MHz. The Radeon R9 280 comes with 3072 MB of GDDR5 memory. This video card has a memory bandwidth of 240 GB/s.
Performance And Power
The Radeon R9 280 graphic card can deliver a single precision computing power of 3343.87 GFLOPS. Furthermore, this video card can achieve a pixel fill rate of 29.86 Gigapixels/s and a texture fill rate of 104.5 Gigatexels/s. The maximum power consumption of the Radeon R9 280graphic card is 200 W.
The Radeon R9 280 graphic card can be plugged to a motherboard through the support of a PCI-E 3.0 x 16 bus. Furthermore, the AMD Radeon R9 280 can support up to Up to 6 displays monitors and supports the following display connectors: "2 x Mini-DP, Dual-Link DVI-D, Dual-Link DVI-I, HDMI". The maximum resolution supported is 2560 x 1600 using the DVI connector
As per the software support, it can support the following programming interfaces and libraries: " DirectX 11.2, 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 enables the combination of multiple graphic cards on a single Motherboard. The Radeon R9 280 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 R9 280 supports the following anti-aliasing techniques: 24 x MSAA, 24 x SSAA, Adaptive AA, EQAA, 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.
