The AMD 785G chipset is manufactured at TSMC on their 55nanometer process, the same as used on the majority of ATI's video cards. ATI calls the integrated graphics on this chipset the Radeon HD 4200. In terms of features on the integrated graphics it has 40 Stream Processors (the lowest end HD 4350 discrete cards have 80), 4 ROPs, 8 Texture Filtering and Address Units and a clock speed of 500MHz. If you remember the Radeon HD 3300 had similar features with a higher clock speed.
The board is an AM3 board meaning that it will not be able to run with AM2+ CPUs as there are two missing pins on the AM3 CPU not present on the AM2. The board uses a 4-phase Power design with another Power Phase dedicated to the chipset. The board supports 140W CPUs including the 955 that was just released by AMD. As the memory controller is on the CPU, the board supports DDR3-1333MHz with 1800+MHz supported through overclocking.
For those expecting better integrated graphics performance out of the 785G you will most likely be very disappointed as this chipset is more akin to what happened when ATI went from the HD 2900XT to the HD 3870, adding support for DirectX 10.1, and UVD without increasing the clock speed or other specifics of the integrated chipset. DirectX 10.1 mainly speeds up performance and improves image quality in games that support it (3 so far on the market.)
One thing I have to take Gigabyte to task on is the 3000 3DMark06 score on the box. The integrated graphics have to be overclocked to 1100MHz from the 500MHz default clock speed. With similar specifications to the HD 3200 I would imagine the performance of the integrated graphics at default clock speed to top out in the 1500s. The average user will probably not reach the high clock speed of 1100MHz for the graphics core. The integrated graphics core has 128MB of HyperMemory increasing performance when enabled. Ultra Durable 3 is GIGABYTE's answer to the challenge of high quality and innovative motherboard design. These boards have 2 ounces of copper for both the Power and Ground layers of the motherboard delivering lower system temperatures improved energy efficiency and enhanced stability for overclocking. GIGABYTE uses Japanese Solid Capacitors with a 60000 Hour life time. Lower RDS (on) MOSFETs reduce power consumption and heat generation.
