The NVIDIA GeForce GT 620 graphic card was introduced into the market on May 2012. This video card is powered by 96 cores each running at a clock speed of 700 MHz. The GeForce GT 620 comes with 1024 MB of DDR3 memory. This video card has a memory bandwidth of 14.4 GB/s.
Performance And Power
The GeForce GT 620 graphic card can deliver a single precision computing power of 268.8 GFLOPS. Furthermore, this video card can achieve a pixel fill rate of 2.8 Gigapixels/s and a texture fill rate of 11.2 Gigatexels/s. The maximum power consumption of the GeForce GT 620graphic card is 49 W.
The GeForce GT 620 video card is compatible with motherboards with PCI-E 2.0 x 16 support. Furthermore, this video card can support up to Up to 2 displays monitors and the display port supported by this video card are: "Dual Link DVI-I, HDMI, VGA". 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 11.1, 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.
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 NVIDIA Fast Approximate Anti-Aliasing Technology (FXAA) is a technology that enhance the image sharpness and quality with great performance efficiency. The NVIDIA FXAA is a great performance technology for eliminating flickering and maintaining the game or video sharpness. It is very easy to integrate into the single pixel shaders.
The NVIDIA PhysX Technology is a powerful Physics engine that harness the power of GPU to deliver incredible effects and physical dynamics to games, with a high level of realism.
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.
