The Tesla K20X video card was launched on November 2012. This video card uses a graphic processor with 2688 cores that run at a speed of 732 MHz. The Tesla K20X integrates a 6144 MB GDDR5 memory. This graphic card memory has a bandwidth of up to 249.6 GB/s.
Performance And Power
As an indicator of computing performance, the Tesla K20X can deliver up to 3935.23 GFLOPS of single precision computing power. Furthermore, the graphic performance of this video card shows a pixel fill rate of 35.14 Gigapixels/s and a texture fill rate of 163.97 Gigatexels/s. The Tesla K20Xgraphic card draws a power of up to 235 W.
The Tesla K20X uses a PCI-E 3.0 x 16 bus interface. .
As per the software support, it can support the following programming interfaces and 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.
