ATI HD4200 graphics card driver introduction
Radeon HD 4200 integrated graphics card will be launched with AMD's upcoming new PISCES desktop platform, Radeon HD The core of 4200 integrated graphics is equivalent to desktop level RV620 Radeon HD 3450 level, supporting DX10.1 and Shader Model 4.1, it will effectively improve the HDR light efficiency and anti -aliasing computing capacity, and reduce the restrictions on AA support, and provide a smoother real -time shadow effect. Add Tessellation technical support. The game uses this technology to reduce the amount of Shader operations and reduce the pair of pairs GPU operation load.
Radeon HD 4200 new integrated graphics card hardware decoding engine is replaced by the second-generation UVD2, which can not only solve the whole process of H.264, VC-1, MPEG-2 videos, but also add a number of improved technologies, such as DVD UPSCaling To HD can increase the 720 × 480 resolution film to 1920 × 1200, and reduce the video blur. In addition, join Dynamic Contrast (dynamic light and dark contrast adjustment) technology, the principle is like Photoshop contrast the picture in dark, optimizing the light and dark position of the image, Corel Windvd9, Cyberlink PowerDVD8 and Microsoft Windows Media
ATI HD4200 graphics card drive product characteristics
Basic characteristics
Equivalent to desktop level RV620 Radeon HD 3450 level
Support DX10.1 and Shader Model 4.1
Effectively improve HDR light efficiency and anti -aliasing computing capabilities
Reduce restrictions on AA support
Provide a smoother real -time shadow effect
Added Tesseellation technical support (the game uses this technology to reduce the amount of Shader computing and reduce the computing load for the GPU.)
You can solve the whole process H.264, VC-1, MPEG-2 video
Improvement characteristics
HD4200 is a characteristic improvement version of HD3200, which has not improved performance. The official frequency is still 600MHz, but compared to the previous as previously added, multiple improved techniques have been added:
1.DVD UPSCALING TO HD.
2.Dynamic Contrast
3.uvd2 (Corel Windvd9, Cyberlink PowerDVD8 and Microsoft Windows Media Player has fully supported UVD2, while Roxio, Nero and Arcsoft will launch related playback software that supports UVD2 in the short term. Cure
4.Accelerated Video Transcoding (AVT) technology (provides 1080P image coding capabilities that are faster than the actual video playback time, support H.264 and MPEG-2 formats. The software can pass the image data through the AVT interface to the Compute of GPGPU. Abstraction layer (CAL), pass the AMD driver to GPU as an image coding work. Currently Cyberlink has officially supported AVT technology, and the new PowerDirector 7 can use AMD The GPU is accelerated by image encoding, and more software will be added in the future to support AVT technology. It will also provide accelerated video transcoding (AVT) technology, and use the driver to achieve the GPU acceleration, so that H.264/MPEG-2 1080p video transcoding speed faster than playback. Cure
ATI HD4200 graphics card drive product parameters
Graphics Category: Integrated graphics card
Chipset: AMD785G (affiliated to the PISCES platform)
Core code: RS880
Process process: 55nm
Number of flow processors: 40

However, the core frequency will be higher and continue to support hybrid fires, so this integrated graphics card 3D performance will be further strengthened.
The specific frequency of the graphics card depends on the setting of the motherboard manufacturer. Generally, between 400-500MHz, most motherboards can manually adjust the core frequency in BIOS.
