HP Tesla K20 Graphic Card - 5 GB GDDR5 - PCI Express 2.0 x16 - PC
The Tesla K20s video card was launched on February 2013. This video card uses a graphic processor with 2496 cores that run at a speed of 706 MHz. The Tesla K20s is equipped with 5120 MB GDDR5 memory. This graphic card memory can achieve a bandwidth of 208 GB/s.
Performance And Power
The Tesla K20s video card can deliver a computing power of up to 3524.35 GFLOPS of single precision computations. As per the video rendering performance, this graphic card can reach a pixel fill rate of 28.24 Gigapixels/s and a texture fill rate of 146.85 Gigatexels/s. When operating, the Tesla K20s video card can consume a power of 225 W .
The Tesla K20s uses a PCI-E 2.0 x 16 bus interface. .
The Tesla K20s 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.
