The R600 core processes vertex, geometry, and pixel shaders as outlined by the Direct3D 10.0 specification for Shader Model 4.0 in addition to full OpenGL 3.0 support. [8] The new unified shader functionality is based upon a very long instruction word (VLIW) architecture in which the core executes operations in parallel. [9]
The Phong reflection model was developed by Bui Tuong Phong at the University of Utah, who published it in his 1975 Ph.D. dissertation. [1] [2] It was published in conjunction with a method for interpolating the calculation for each individual pixel that is rasterized from a polygonal surface model; the interpolation technique is known as Phong shading, even when it is used with a reflection ...
Fragment (pixel) shader Shader processing individual pixels or fragments (values that may potentially become pixels). Frustum culling A stage in a rendering pipeline, filtering out 3D models whose bounding volumes fail an intersection test with the view frustum, allowing trivial rejection. Fresnel
In recent GPU generations, the pixel shaders now are able to function as MIMD processors (now able to independently branch) utilizing up to 1 GB of texture memory with floating point formats. With such power, virtually any algorithm with steps that can be performed in parallel, such as volume ray casting or tomographic reconstruction , can be ...
The Mobility Radeon HD 2300 is a budget product which includes UVD in silica but lacks unified shader architecture and DirectX 10.0/SM 4.0 support, limiting support to DirectX 9.0c/SM 3.0 using the more traditional architecture of the previous generation. A high-end variant, the Mobility Radeon HD 2700, with higher core and memory frequencies ...
The Radeon R700 is the engineering codename for a graphics processing unit series developed by Advanced Micro Devices under the ATI brand name. The foundation chip, codenamed RV770, was announced and demonstrated on June 16, 2008 as part of the FireStream 9250 and Cinema 2.0 initiative launch media event, [5] with official release of the Radeon HD 4800 series on June 25, 2008.
The game engine provides most of the features necessary for creating classic 2D graphical adventure games.Although originally built as a 2D graphics engine, with a built-in script interpreter for implementing game logic, the Wintermute Engine provides support for the combination of real-time 3D characters and 2D backgrounds, a combination sometimes known as "2.5D", that has become the de facto ...
AMD PowerTune is a series of dynamic frequency scaling technologies built into some AMD GPUs and APUs that allow the clock speed of the processor to be dynamically changed (to different P-states) by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw, heat ...
