Final thoughts and rating

AMD's new 785G chipset is an updated version of the popular 780G model that debuted well over a year ago. The graphics portion of the chipset, Radeon HD 4200, has been upgraded by pulling DX10.1 and UVD2.0 features from a discrete Radeon HD 3000-series card, but the core speed, at 500MHz, remain the same. CPU support is present for the very latest AMD Socket AM3 chips, and that means the use of DDR3 modules on most boards. Keeping costs low-ish, we'll see the majority of motherboards pair up the RS785G northbridge with the SB710 RAID5-less southbridge.

The chipset makes sense if building a low-cost PC that's good for (very) casual gaming and multimedia usage, although the lack of surround-sound multi-channel LPCM (audio) will put some potential punters off. We can see folk opting for a machine akin to the system setup used for evaluation, replete with a Phenom II X2 550 BE chip and 4GB of DDR3 memory. Add in a £65 785G board and you'll have decent change from £200.

Looking at it pragmatically, the ASUS M4A785TD-V is a well-specified interpretation of 785G that features a decent layout and a number of added extras - SidePort memory, for example - not found on the most budget boards. Pricing, too, is keen, at £70, but we'd like to see a BIOS-saving option and better onboard audio, as it's likely to be used in an HTPC environment.

AMD's 785G is an incremental upgrade from 780G and we can recommend it to readers looking for a new system that doesn't break the bank. If you can live with integrated graphics and want a no-nonsense, solid system, it's as good as most, yet doesn't tick all the HTPC boxes - a lack of 8-channel LPCM being an obvious omission.

Focusing on the sample motherboard, the ASUS M4A785TD-V is chock-full of features and arrives with an attractive etail price of £70. A few suggested modifications would take it from being good to great.

HEXUS Rating

We consider any product score above '50%' as a safe buy. The higher the score, the higher the recommendation from HEXUS to buy. Simple, straightforward buying advice.

The rating is given in relation to the category the component competes in, therefore the motherboard is evaluated with respect to our 'mid-range components' criteria.

Just to clarify a couple of things: from the look of that block diagram, this will Hybrid Crossfire with any 4000 series GPU up to a 4650? is that right? Also, does the IGP on this support 2 digital outputs at once? Again, the block diagram suggests otherwise (and it would be a first for AMD's IGPs, AFAIK)…

Any chance of some testing to see what kind of performance boosts Hybrid Crossfire can provide to the different GPUs? A 4650 isn't exactly a slouch at low resolutions anyway…
What was the maximum CPU speed the board was able to get to whilst overclocking?

USB performance is dreadful. AMD really need to sort this out for their next range of chipsets.

Perhaps what's more worrying is how badly the USB performance of SB710 is compared to SB700 / SB750. If you look back at the 780G review the SB700 stands up very well next to the G45. I'll be interested to see more 785G reviews to find out if this is a chipset issue or if it's just a problem with the ASUS implementation…
disappointing, the HD4200 should have been a genuine 4xxx series GPU sporting 80 shaders.

this does not bode well for the AMD Tigris mobile platform due next month.

That block diagram shows AMD-recommended pairings with the board. However, looking at like-for-like architectures, it is best paired up with Radeon HD 3450.

Yup, it support dual digital outputs.
