AMD 785G + SB710 čipset

Today we get to officially unveil the 785G, the latest in integrated graphics chipsets by AMD for AMD. As the name implies, there is very little separating 785G from its predecessor (780G) and we’re quite ok with that. In fact, the only reason not to get a 780G is addressed by the 785: the new chipset supports 8-channel LPCM audio over HDMI. The lack of TrueHD and DTS-HD audio bit-streaming remains but neither is this feature supported on other chipsets. We also see a jump from HDMI 1.2 to 1.3 standards. The rest of the major improvements are strictly related to video playback duties. We jump from Universal Video Decoder (UVD) 1.0 on the 780G to UVD 2.0 capabilities on the 785G. The video decode engine supports decoding multiple HD streams (useful for picture-in-picture on a Blu-ray movie) and additional post processing effects if you are not a big video purist. Also new is the 785G's ability to perform detail enhancements on the fly.

The graphics side has not really changed that much. The new GPU is based off the RV620 core and is roughly the same size/complexity as the old one. The 785G’s PowerPlay technology is improved with the core constantly adjusting clock speeds based on GPU utilization with a 60MHz target when idling compared to 500MHz at full load. AMD adds DirectX 10.1 support but stream processor count and clock speeds have not changed. Thus gaming performance remains mostly unchanged. The Radeon HD 4200 is where all the action is with this update but the more things change, the more they remain the same. We still have the traditional Northbridge/Southbridge layout with the NB supporting a 2GHz HyperTransport link compatible with the latest Socket AM3 processors. The 22 PCI Express 2.0 lanes are still around along with the four lane PCI Express 1.1 lanes supporting the A-Link Express connection between the two bridges.

The SB710 is essentially an updated SB700 with ACC (Advanced Clock Calibration) support, or looking at it a different way, a cost reduced SB750 without support for RAID 5 arrays. The SB710 has six 300MB/s Serial ATA ports with RAID 0, 1, and 0+1 support plus a single IDE port supporting two drives so JMicron and Marvell are held at bay on these systems. Twelve USB ports and a high-definition audio interface round out the SB710 as native GbE support is still missing. On the ECS board we received this embedded GPU is clocked at 700MHz, and as a Radeon HD 4000-series product, it brings with it support for DirectX 10.1; this ECS board even comes packed with HDMI, DVI and VGA outputs and as such it sounds like an optimal HTPC and office PC chipset. But the biggest change is the integration of that R4200 graphics core.

MSI 785G serija ploča

MSI 785G Series mainboards, aiming at fitting consumers' demand for environmental protection and energy saving, introduced APS(Active Phase Switching).Auto power supply switch depending on system loading leads to more efficient power-using. MSI saves the earth and saves your money. In addition to more emphasis on energy-saving, MSI 785G series mainboards are equipped with exclusive Easy OC Switch. On bios design , all series of MSI 785G mainboards are equipped with state-of-the-art bios upgrade and back-up technology. Besides avoiding from risk of traditional bios upgrade, users can have system recovery through USB with bios content.

MSI 785G mainboard with built-in ATI Radeon HD 4200 GPU makes it convenient for users to connect various audio and video utility. Besides regular DVI video output, MSI provides HDMI for audio and video output. With one single HDMI lane, high definition audio and video outcome can fully satisfy next generation's high definition demand.


Among the new products are the 785GT-E63 ATX and 785GTM-E45 micro-ATX. Both motherboards support the complete range of AM2, AM2+ and AM3 socket processors, with DDR2 memory running at up to 1066 MHz speeds depending on the processor. The 785GT-E63 powers its processor with a 4+1 phase VRM. Four DDR2 DIMM slots are provided. In both motherboards, SidePort memory is absent. The IGP connects to its displays using DVI-D, D-Sub, and HDMI. The 8-channel audio CODEC also provides optical SPDIF output. One of the six SATA II ports the southbridge provides is assigned as eSATA. The 785GTM-E45 has a skimpier layout, with just two DDR2 DIMM slots to go with it. No eSATA here, with all ports internal. The 785GTM-E45 is priced at 69 Euro, with the 785GTM-E45 at a mere 6 Euro less, at 63 Euro.
