AMD's New 780G Chipset

With today's introduction of its new 780G chipset, AMD is finally enabling users to build an HTPC or multimedia computer for HDTV, HD-DVD or Blu-ray playback that doesn't require an add-in graphics card. (AMD already included HDCP support and an HDMI interface in its predecessor chipset, the 690G.) The northbridge chip of the new 780G chipset also features an integrated Radeon HD3200 graphics unit that can decode any current high-definition video codec. As a result, CPU load is decreased to such a degree that even a humble AMD Sempron 3200+ is sufficient for HD video playback. Also, while Intel's chipsets get more power-hungry with every generation, AMD's newest design was designed with the goal of reducing power consumption. (Compare Prices on Radeon Video Cards)

The Gigabyte GA-MA78GM-SH2 formed the basis for the review platform.

The older 690G chipset was originally designed by ATI, and was essentially just rebranded with the AMD logo after the two companies merged. The new 780V and 780G chipsets unveiled today are the first chips to be designed since AMD's acquisition of ATI, and can thus be considered "real" AMD chips.

AMD has every reason to be proud of its design, which is one of the best chipsets we have ever tested. It bests Intel's chipsets in functionality, power consumption and production process. With the move to 55 nm, AMD was able to lower the power consumption of its chipset. Intel, on the other hand, still manufactures its G33 and G35 chipsets at 90 nm, resulting in a much higher thermal dissipation loss. The 780G chipset sets a new record for the lowest power consumption.

I would like to know can i run a video card with this mother board,with all the high demand for great video quality in these new video games such as Crysis, BioShock, Jericho and many others that require a high end video card how am i suppose to play these games without one

You just put in any PCI-E video card in the X-16 slot. With the appropriate processor and beefy enough video card, games are not a problem. The real beauty is that the onboard video is plenty for casual, older games at acceptable rates and also makes for a great low power HD media center computer.

I do not get it, how come 2600XT is more faster than 3450 ? I thought 3450 is newer than 2600XT. Please explain

What about the northbridge overheating issue everyone is talking about? I've bought this board only to find out it has idle temps of 80C at the northbridge. I'm planning on buying an after market cooler to stabilize it.

gerro1977,

What revision is your board? I just received this board and it's the new revision 1.1 which has a bigger heatsink (you can see the pictures from the gigabyte site for both revisions 1.0 and 1.1). I am getting my CPU soon and want to also check the northbridge temperatures. What can I use to measure the temps?

Thanks

I'm cooling my G780 on GA-MA78GM-S2H rev1.0 with additional pentium 3 box coller heatsink (fits perfectly) and radeon 3450 with p3 box fan :) - it works fine

Does anyone know if the radeon HD4850 works on this board with hybrid graphics and crossfire.

Unfortunately, I'm using the rev 1.0 board. I fitted it with an HR05 heatsink from thermalright and its now just warm to the touch not hot. I'm using everest to monitor my temps. Aux now registers at 37 C, though I'm not really sure if its the NB temp. You can also use riva tuner among others.

I have a ASUS M3A78 EHM HDMI and I have a temperature of only 33ºc with my X2 BE-2350... I'm going tu put a HD3450, but i have a doubt... If i'm only in 2D graphics (like the desktop) the board switches to the HD3200? And when I need power does it "switch" to HD3450?
