The soon to launch AMD 785 chipset has better DirectX 10.1 based graphics and this will be the main difference compared to current integrated AMD 780G mainstream / value chipset.

AMD 780G has a DirectX 10 based IGP core and its GPU is branded as Radeon HD 3200, while AMD 785G will get a Radeon HD 4200 brand which definitely confirms DirectX 10.1 capable graphics from the HD 4000 generation.

We believe that the IGP is based on some sort of RV710 version clocked at 500MHz, but probably crippled to meet the 15W TDP requirement of this chipset segment. The chipset interconnects with SB710 and comes in early Q3 2009.
