AMD 785G: The Venerable 780G, Evolved

[JohnnyLucky]

Interesting article because yesterday I was looking at AM3 micro-atx motherboards at a local electronics store. I was thinking of building an energy efficient pc suitable for a home theater pc and some general purpose uses. I saw a mobo with the 785 chipset and I wasn't familiar with it. There were other AM3 boards on display but inventories were very low and most of the 790 chipset micro-atx boards were not in stock.

amd 785G with intergrated HD4200 + discrete HD5870x2 + Phenom II x4 965 perfect matched

Looks like Intel and Nvidia are doomed in the integrated graphics market. Nvidia said they wouldn't be making any new chipsets and LGA 775 is a EOL socket. Looks like AMD/ATI will be the only reasonable integrated solution from now on.

I don't see the need to make it capable of gaming, gamers will buy a dedicated card. IGP should be designed to handle the needs of general pc users and HTPC enthusiasts.

at the end of the article it states that the ATI HD4350 is far better than any of these IGPUs, how much better? is there a review around?

what's the risk of overclocking the 785g igp? would it run on high temp and possibly damage the gpu? Coz when i overclock, it is constantly running at 800mhz. But by default, speed goes down to 200mhz and automatically raised to 500-600mhz with heavy graphix.

the best thing in this board is AAC in bios comming from SB710, i buy a phenom x2 545 set AAC to four cores and unlocked the phenom to X4 945 so i turn a cpu of $90 in to one of $145

You shouldn't have any problems as long as the northbridge has good ariflow with a decent heatsink. If you can monitor the temperature I would go as high as the temps would allow. IF it was to overheat it would shut down then you should have to reduce the clockspeeds, no real harm done.

tnx man, nice to hear that. but are you pointing a decent heatsink for the northbridge or processor?

There does seem to be some slight confusion with AMD's naming conventions. However, the reason I went with AMD is because in my opinion this slight marketing ploy (785g vs. 780g), is nothing on par with the tricks nVidia pulls. I've been stung with discrete cards, i.e. Geforce 4200 Ti to 5600 FX, as well as chipsets..6100 vs. 7025/7050. In both cases I wasn't overly improved with the performance increase and the trend seems to be continuing. I do like NVIDIA's driver stability and CUDA support but not so much these misleading names.

If you have an AMD 690g chipset you can be rest assured that the 780g will offer a nice boost in performance..and that the 785g will offer some cool CPU tweaks, as well as stream processing. Lets also not forget the huge overclocking potential of the 700 series chipsets.

I could have gone with Geforce 8200 onboard but I thought no..this time AMD gets the limelight for the reasons mentioned above. Having installed the 785g hardware and tinkered with some CPU+GPU overclocking, I am thoroughly impressed by the performance, features and stability of the product especially considering it's price. On the Intel side there is only Geforce 9200 IGP that would interest me, but why do that when Phenom II offers similar or better performance than Core 2 and in some cases, even core i3/i5/i7? There is not a big enough draw from Intel and if I want fast gaming I'd just get a discrete graphics card.

I have the Gigabyte ga-785gmt-usb3 mother board with a small AMD Athlon2 x2 250 and 1333 kingston hyperx 1333 memory and with tis combo work great for mid gaming. The family likes to play WOW and my new MOBO with the 785 outdoes my wifes and dedicated video. She runs a geforce 9500gt. Using the faster 1333 memory ups the memory speed for the video card onboard. I do have it OC to 600 on the core and 1400 on the memory. Love it for the price.
