AMD 785G Chipset Launch: ASUS and Gigabyte
IGP Multimedia Performance
The 785G is equipped with an integrated Radeon HD 4200, a boost up from its predacessor the 780G, which was equipped with a HD 3200. Besides the obvious improvements like the integration of the newer HD 4000 series GPU engine, the HD 4200 also receives AMD's UVD 2 feature set which offers decode acceleration for MPEG2, H.264 and VC1. The UVD feature set also includes support for post processing effects such as de-interlacing, de-noise and pull down detection. Version 2 of UVD adds support for dynamic contrast, bicubic scaling, picture-in-picture acceleration as well as image quality enhancements like color vibrance and flesh tone enhancement.

Overall, the Radeon HD 4200 provides a significant amount of video playback acceleration, certainly enough to handle general multimedia and HTPC playback duties with ease without the need for a discrete graphics card. This is makes the 785G a good choice for use in HTPCs where you won't necessarily have a discrete graphics card. The ability to handle HD video playback with the IGP means you can use the money saved on the graphics card for a DVR / TV tuner card, in the case of a HTPC.
