Before presenting AMD800 chipset, AMD AMD785G chipset which brings an improvement from the previous chipset AMD780G. Why AMD is still present 78 variants of the chipset series although there are AMD790GX? AMD’s answer was indeed only knows. Clearly, the improvement of the AMD785G AMD780G is intended for the use of high-definition multimedia with better support than ever before (AMD780G).

This product has advantages that are not owned by the AMD780G chipset, such as the ability to picture-in-picture video acceleration, support for ATI’s Stream technology, support DirectX 10.1, the use of lower power consumption (lower power usage) and has full compatibility with Windows 7.

Featured AMD785G

One of the things that are different in this product, namely the use ATI Radeon HD 4200 chipset for onboard graphics business. The fundamental difference is the full support of DirectX 10.1 and Shader Model 4.1 and well-Hybrid CrossFireX support. But strangely, not on his official site (or not) listed the standalone graphics card support. We assume that this graphics card is the onboard chip ditandem with standalone graphics card Radeon 3400 series.

AMD785G chipset Northbridge competitor is a chipset SB710 southbridge. What improvements have compared SB700? Among other features of OverDrive support for version 3.0. Overdrive 3.0 promising monitoring processor speed settings and a more intelligent according to profile applications running. Also like the SB750 southbridge, this product has also been accompanied by features of Advanced Clock Calibration (ACC), which can improve performance (especially when you tamper with the system through overclocking method). This indeed was introduced simultaneously with AMD790GX chipset which is the tandem of SB750. But still the same with SB700, SB710 also do not support RAID 5, though it supports RAID 0,1, and 10 arrays. RAID 5 is only supported by the SB750 southbridge.

Because of using different graphics chipsets, clearly different features dihadirkannya. Like the AMD 785G chipset, this product also supports Video Details Enhancements called UVD 2.0, where the previous chipset only supports UVD 1.0. Differences and additional features can be seen on the table ranging from DirectX support, engine clock, UVD, shader models, Accelerated Video Transcoding, Scaling and High Quality Video ATI PowerPlay all of which are not owned by the AMD 780G chipset.
