It is a technique to perform general-purpose computations in GPU using appropriate framework, an API and a programming model, such as OpenCL, Microsoft's DirectCompute
, and NVIDIA's CUDA.
MediaShow 5 is a fast and easy photo/video organiser, which uses DirectX 11 DirectCompute
acceleration on PCs powered by AMD A-Series APUs and enables accelerated facial recognition up to 1.2X faster3.
AMD was the first company to provide support for both OpenCL and DirectCompute
11 solutions, which are both now leading industry standards.
The Brazos platform also supports the latest DirectCompute
and OpenCL interfaces.
Graphics accelerators with DirectX 10 and later support can utilize DirectCompute
API for general purpose computing too.
The demonstration showed a single Llano APU chip processing three separate CPU and GPU tasks simultaneously on Windows 7, including calculating Pi to 32 million decimal places, Microsoft's nBody DirectCompute
, and decoding HD video from a Blu-ray.
The NVIDIA Quadro 2000 and Quadro 600 are built on industry standards, including OpenGL 4.1, DirectX 11, Shader Model 5.0, DirectCompute
In addition to Microsoft DirectX with DirectCompute
, software developers can also build enhanced applications using OpenCL via the ATI Stream SDK, which further underscores AMD's commitment to industry standards.
ZOTAC International, the world's largest manufacturer graphics cards, mini-ITX motherboards and mini-PCs in the channel, today unveils the world's first IONao Upgrade Kits featuring a ZOTAC small form factor motherboard and ZOTAC IONao graphics card for a combination that delivers phenomenal value with premium graphics and outstanding user experience.AaA ZOTAC IONao graphics card with 16 unified shaders and 512MB of DDR3 memory empowers the ZOTAC IONao Upgrade Kits with high-end features such as NVIDIAA CUDAao and PureVideoao HD technologies, DirectXA 10.1, DirectCompute
, OpenGLA and OpenCL compatibility for a high-performance and feature rich experience.
...The next big evolution in the API world has come with DirectX 11 (DX11), but we believe that's a part of the experience," Hara said, adding that other technologies, including 3D stereo and physics, are also important.<p>DirectX 11 was introduced with the release of Windows 7 and includes several improvements over previous versions of the graphics programming technology, including tessalation for displaying smoother curved surfaces, support for multi-core processors, and DirectCompute
, which allows developers to harness the parallel processing power of graphics chips for other tasks, such as video editing.<p>"To us, being out of sync with the API for a couple of months isn't as important as what we're trying to do in the big scheme of things for the next four or five years.
