While a lot of the limelight has been pushed on Intel and Core i7 based boards, AMD still has managed to make a good dent in the market with Phenom II processors. These have to be the most versatile processor with 64-bit instructions, native 3 and 4 core designs as well as support for DDR2 or DDR3 memory through the on-die memory controller, something Intel has no intention of doing. Phenom II is definitely the big processor to have for a small budget.

While the processors keep coming, chipsets to support it are still making their way from AMD's fabs. And since AMD has taken over ATI's graphics and chipset departments, their 7 series chipsets have been anything but disappointing, especially with regard to the integrated graphics.

To that end, we have the latest instalment from AMD's chipset division. Fresh from NDA today we have the 785G chipset. Based around the 790GX chipset, this puppy is aimed at the budget users. However, it does get one major upgrade, DX10.1 IGP, something the 790GX doesn't.

Unfortunately, due to the early release there is no Newegg price on this board.

The Box and What's Inside

Package and Contents

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

Starting off as we normally do, we check out the package and contents. The board is packed in a small box, so right off the bat we know that this board uses the Micro ATX format. The box is coloured in the standard UD3 decorations with only the model number different from the other boards.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

On the back there is just marketing hype about UD3 and the 2 ounce PCB. There are no pictures of the board on the back.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

For a small board, GIGABYTE packs in three user manuals; one for the board and two multi language quick start manuals. The drivers are provided on a DVD for both XP, Vista and early Windows 7 support.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

For the accessories bundle there are only two SATA data cables and a single IDE cable. Very small, but enough to get you started.

The Motherboard

The Board

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

Now we start on the board itself. With reference to the small box, we were right on the form factor. Unless the box is like a TARDIS there are no surprises on the board size.

GIGABYTE uses its familiar blue PCB. The layout is extremely clean, even for a Micro ATX board. The 24-pin power connector, FDD and IDE connector are all located behind the four DDR2 memory slots. That's right; this board makes use of DDR2. The 4/8 pin power connector is located at the top left, behind the USB/PS/2 combo port.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

The board's power regulation system is a 5 phase voltage system for the CPU using all solid state components. There are no heatsinks or heatpipes to cool the Mosfets, however, the 785G Northbridge and SB750 are both passively cooled.

The new AMD 785G chipset boasts the same features as the 790GX with one major upgrade; that's a new IGP capable of DX10.1 graphics. Included from the 790GX brother is support for Sideband memory which puts a 512MB DDR3 memory chip clocked at 400MHz on the board as cache memory for the IGP. However, you can also use system memory for extra capacity, though it is slower to access.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

On the right hand edge of the board GIGABYTE places five of the six SATA ports. The sixth SATA port is routed to the rear I/O panel for convenient eSATA port use.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

Moving to the rear I/O, we get to see what GIGABYTE has in store for this board. In all, a very good setup. There are a total of three video output slots; a CRT D-SUB, DVI-I and HDMI outputs. Digital audio is handled through a Toslink S/PDIF port and a single eSATA port is included for high speed mass storage connections.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

Lastly on the board front we have the expansion slots. There is a single PCIe x16 slot for a discrete GPU if you don't want to use the onboard graphics. Or if you want to combine a discrete ATI graphics card with the onboard graphics to help bolster performance, you can also do this. A single PCIe x1 slot and two PCI legacy slots make up the rest of the expansion possibilities of this board.

BIOS and Overclocking


GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

Moving along to the configuration side of things, we now come to the BIOS setup. GIGABYTE's familiar BIOS setup greets us with the Award 6 Modular setup with all of the overclocking settings located under the Motherboard Intelligent Tweaker (M.I.T) menu.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

Under the M.I.T. menu you can change quite a few settings including FSB, CPU ratio, voltages for various components on the board etc. - If you're using the IGP you can even overclock the IGP core clock and the sideband memory.

Validation Link:

We didn't get a lot of time to overclock the board unfortunately, so we had to stick to stock settings due to time constraints. However, we will revisit this during a later article testing the 790GX vs.785G. We did all our tests at stock speeds.

Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the motherboard. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.

And once again, under real world gaming all three are right on top of each other.

Power Usage and Heat Tests

Power Consumption

We are now able to find out what kind of power is being used by our test system and the associated graphics cards installed. Keep in mind; it tests the complete system (minus LCD monitor, which is plugged directly into an AC wall socket).

There are a few important notes to remember though; while our maximum power is taken in 3DMark06 at the same exact point, we have seen in particular tests the power being drawn as much as 10% more. We test at the exact same stage every time; therefore tests should be very consistent and accurate.

The other thing to remember is that our test system is bare minimum - only a 7,200RPM SATA-II single hard drive is used without CD-ROM or many cooling fans.

So while the system might draw 400 watts in our test system, placing it into your own PC with a number of other items, the draw is going to be higher.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

Power consumption between the 790GX and 785G chipsets is almost identical.

Heat Generation

As a new measure, we are now monitoring the heat generation from the key components on the motherboards, this being the Northbridge, Southbridge (if it contains one) as well as the Mosfets around the CPU. The results are recorded at idle and load during the power consumption tests.

GIGABYTE MA785GPM-UD2H 785G AM3 Motherboard

Both the new 785G and older 790GX chipsets keep similarly cool with the 785G having the edge, while the 790FX runs noticeably warmer.

Final Thoughts

AMD's chipset lineup has no intention of stopping. In fact, it's proven they are willing to keep things going. AMD's 7 series chipsets have been extremely impressive and the 785G chipset is nothing short of this either.

While we have only tested the first board we've been given so far, along with this one being Micro ATX, we don't know the full potential yet. And due to the limited time of testing we didn't get a lot of time to check out the overclocking or onboard graphics. However, we are coming back to a second article later next month with testing of the 785G's IGP vs. the 790GX's, so stay tuned for that one.

On the GIGABYTE implementation of this board, everything is just how we would expect. However, the accessories could perhaps be a bit more in depth to better round off the package.
