I have no qualms recommending this board to our readers for use on their new or upgraded PC
Feature-rich, Good Performance, Stable operation, Hybrid Graphics, Onboard UVD, Independent DVI-D and D-Sub controllers, Good 8-channel audio, HDMI out, Good assortment of I/O ports.
HyperTransport 3.0 works only with Phenoms, Northbridge tends to heat up.
HyperTransport 3.0
As said, the 780G chipset supports HyperTransport 3.0 link when coupled with the new AM2+ processors (read, Phenom CPUs, for now). Earlier chipsets would work with HyperTransport 1.0 that used to run at 1 GHz with a Dual Data Rate (DDR). The HT3, on the other hand, runs at 1.8GHz and has a theoretical throughput of 15GB/s.
This huge amount of bandwidth is essential to the working of the 780G's DX10 graphics core as it has to constantly keep interacting with the memory controller inside the CPU to use the RAM. This explains the huge jump in graphics performance as compared to last generation chipsets.
Radeon HD 3200 and Hybrid Graphics
As I said, the HD 3200 powers the 780G's graphics core and is nearly the same as ATI's Radeon HD 3450 with both of them using 40 stream processors and a 55nm fab process. The only difference between them is that the HD 3200 in the 780G runs at 500MHz while the discrete HD 3450 runs at 600MHz.
Nonetheless, expect a similar performance from the on-board graphics sub-system.
Apart from that, the HD3200 has two indelendent display controllers that allow you to use two monitors at the same time without using any discrete graphics cards. Needless to say, on the motherboards, these will be implemented by using a VGA (D-Sub) and a DVI-D interface, like this board has.
We spoke about Hybrid Graphics being introduced on the 780G chipset and here's how you can benefit from it.
The HD 3200 has enough muscle power to let you play almost all DX10 games at respectable frame rates (at low resolution and low-to-medium graphics). Moreover, when you use an HD 3450/3470/2400 in tandem with the on-board GPU (provided you have Vista OS), what you get is almost double the performance since it works in Hybrid Graphics mode and combines the power of the HD 3200 and the HD 3450 to give you better frame rates and graphics quality dirt cheap. This is a great option for the cost conscious-gamer who, somehow, is always short of cash for better hardware. We'll be publishing a separate article that will shed more light on Hydrid Graphics through some thorough testing across various discrete ATI GPUs.
Hi, I just want to know the price of the motherboard Gigabyte MA78GM-S2H in kolkata. Thanks Abhijit SAha

i have the same config as urs, does ur northbridge heat up a lot too, mine is 82 c at idle and crossed 100 c at load

What software you are using to check the temperature.

i used speedfan, n also amd overdrive the temp3 shows northbridge temp

Mine is showing as 85 at idle.

so im guessing this is normal then, but would definately like to know if there is any way to cool it down

I think a better cooler for NB is required because this chipset preformance is much better than other NB. It should be hot.

any suggestion about chipset coolers?

slight improvement only.There is no appreciable improvement over other chip sets except 3D mark 2005!!!

Sudeep, since this is a mATX motherboard with HDMI and DVI out, it is also targeted at the HTPC market. So why don't you do some benchmarking in the video playback side. Is it capable of doing BluRay 1080p content? If it is then this MB is best suited for HTPC than anything else.

since it has a Trusted Platform Module(TPM) header, does that mean we can expect hacked versions of the mac TPM chip and install OS X legally??

why does the 3DMark 2006 (Onboad) look like 3DMark Vantage? or is it really Vantage?

does it have side-port display memory cache? This feature will improve performance of onboard graphics and hybrid crossfire graphics (if any attached)

The Effect of Side-Port Memory, Core Clock and Phenom Processor on 3D Performance -------------------------------------------------------------------------------- 3DMark06 score at 1284x1024: - Athlon 64 X2 5000+, no side-port memory, 500MHz core: 686 - Athlon 64 X2 3800+, no side-port memory, 900MHz core: 1354 - Athlon 64 X2 5000+, 64MB side-port memory, 500MHz core: 1168 - Athlon 64 X2 3800+, 64MB side-port memory, 1023MHz core: 1670 - Phenom 9500, no side-port memory, 500MHz core: 1444 - Phenom 9600, no side-port memory, 900MHz core: 1908 - Phenom 9600, no side-port memory, 1023MHz core: 1988 - Phenom 9600, 64MB side-port memory, 1023MHz core: 2034 As expected, core clock affects 3D performance almost linearly (?), but processor clock does not affect it much. When a dual-core processor is used, side-port memory increases 3D performance greatly. A notable fact is that when a Phenom (quad-core) processor is used, 3D performance increases greatly (1444 vs. 686 at 500MHz core!), but in this case side-port memory has little effect.

If a GPU 9300GT XFX(1 gb) is added in Pci slot, will hybrid graphics technology will work or not? Does hybrid graphics means support only to Ati cards or also nvidia cards?
