Gigabyte GA-MA785GMT-UD2H: Specifications

Gigabyte also has several different 785G-based motherboards ready for the launch today. We have two of them in our labs, the ATX Gigabyte GA-MA785G-UD3H and the mATX Gigabyte GA-MA785GMT-UD2H. The two boards are similar overall but differ in a few key areas. First, let's take a closer look at the mATX GA-MA785GMT-UD2H.

The Gigabyte GA-MA785GMT-UD2H, the smaller of the two Gigabyte boards we have, is actually most similar to the ASUS M4A785TD-V EVO we just checked out in the previous pages. Just like the ASUS, the GA-MA785GMT-UD2H is packed with features including support for Hybrid CrossFire, DDR3 support and integrated 128MB SidePort memory. The most obvious difference between the two boards is the form factor, where the Gigabyte is a compact mATX board.

Taking a look at the specification sheet, you'll notice that the GA-MA785GMT-UD2H is nearly functionally identical to the ASUS, except that its smaller mATX frame means it has less expansion slots and is most noticeably missing the second PCI-E slot. While the Gigabyte and ASUS use different audio codecs and Ethernet LAN chips, they are functionally identical with essentially the same features. The one area where the two boards diverge in feature sets, other than their obvious size and expansion differences, is the Gigabyte's addition of an iTE IT8718 chip which allows for floppy disk drive support via a single FDD connector. This isn't exactly a killer feature, but some users might find it handy.

In terms of features, the Gigabyte GA-MA785GMT-UD2H is equally well equipped as the ASUS M4A785TD-V EVO. It also comes with a a fairly typical bundle including a IDE connector and two SATA connectors.
