AMD 785G chipset (codenamed RS880), released on August 4, 2009, is the successor to AMD 780G chipset that has been used widely since its release on March 2008. The main difference is a new IGP called Radeon HD 4200 (codenamed RV620, clocked at 500MHz, but the number of stream processors is 40, the same as HD 3200, RV610). Southbridge is SB710, a minor revision of SB700. Improvements over 780G are:
Integrated Graphics HD 4200
That's it! The other articles neglected this aspect, as expected usually.
GIGABYTE 785G Chipset Motherboards
Here are brief descrptions of the available models and their differences.
MicroATX, DDR2 SDRAM
Basically the drivers are common to all the above models.

Southbridge is SB710, a minor revision of SB700. Improvements over 780G are:
Integrated Graphics HD 4200
- DirectX 10.1 support
- 2nd generation Unified Video Decoder (UVD 2)
- Full hardware decode acceleration of H.264/VC-1/MPEG-2 (full hardware decode acceleration of MPEG-2 is not supported in HD 3200?)
- Hardware decode acceleration of a secondary video stream (Picture-in-Picture) (10-20% CPU usage decrease)
- Improved ATI Avivo Video Post Processor
- Enhanced DVD up-conversion to HD
- Automatic dynamic contrast adjustment
- Multichannel LPCM over HDMI (no PAP, no HD audio bitstreaming, of course). Update: Only stereo LPCM in addition to DD/DTS bitstreaming is supported over HDMI
- ACC (Advanced Clock Calibration) support

AMD Chipset Roadmap
VR-Zone - AMD 800 Series Chipsets Launch Schedule (September 4, 2009)
Quote:
VR-Zone has put together a roadmap of the AMD 800 series chipsets line-up slated for release in Q2 next year. AMD 890FX/GX + SB850, part of the "Leo" platform for enthusiasts is slated for launch in April 2010 replacing the current AMD 790FX/GX + SB750 chipset. AMD 880G + SB810, part of the "Dorado" mainstream platform will come along in May 2010 replacing the current AMD 785G + SB710 chipset. AMD 880G comes with enhanced IGP graphics performance which we presume is DX11 capable and sports the next generation ATI Hybrid graphics technology. Overall, the AMD 880G board could be priced cheaper due to the integrated clock generator and integrated Broadcom MAC.
