ASUS, DFI and Gigabyte prepare RD790, RD780 and RX780 motherboards

AMD motherboard partners displayed RD790-based motherboards at Computex 2007. ASUS, DFI and Gigabyte have RD790 motherboards on display. Gigabyte is the only partner to have a live demonstration of RD790, from what we have seen. The Gigabyte GA-M790-DQ6 features four PCIe 2.0 x16 slots capable of dual x16 or quad x8 configurations.

The live demo of the Gigabyte GA-M790-DQ6 did not have two ATI Radeon GPUs operating in CrossFire. Instead, Gigabyte equipped the RD790 demo system with a single ATI Radeon HD 2600 XT.

The Gigabyte GA-M790-DQ6 does not have any PCIe x1 slots. However, the GA-M790-DQ6 features two standard PCI slots. Gigabyte also equips the GA-M790-DQ6 with a Realtek ALC889 high-definition audio codec capable of 106dB signal-to-noise ratios.

ASUS had the M3A32-MVP Deluxe on display. The upcoming ASUS M3A32-MVP Deluxe supports Socket AM2+ processors with HyperTransport 3.0, or HT3. The board features dual PCIe 2.0 x16, three PCI and one PCIe x1 slots. The ASUS M3A32-MVP Deluxe will also support DDR2-1066 memory.

ASUS equips the M3A32-MVP Deluxe with an elaborate heat-pipe cooling setup. The heat-pipe cools the RD790, SB600 and accompanying system memory.

DFI had the LANPartyUT RD790-M2R on display. The LANPartyUT RD790-M2R features four PCIe 2.0 x16, two PCI and one PCIe x1 slots. DFI only claims HyperTransport 1.0 support with the LANPartyUT RD790-M2R. Nevertheless, the LANPartyUT RD790-M2R features a six-phase Vcore and one-phase digital PWM. Additionally, the DFI LANPartyUT features dual Gigabit Ethernet ports with teaming technology and DFI Bernstein eight-channel audio.

ASUS had additional AMD 7-series motherboards on display – the M3A-MVP and M3A. The ASUS M3A-MVP features the mainstream RD780 chipset with a cut-down PCIe lane configuration. ASUS equips the M3A-MVP with two physical PCIe 2.0 x16 slots. The PCIe 2.0 x16 slots default to dual eight-lane configurations when both slots are occupied.

The ASUS M3A-MVP also features three PCIe x1 and two PCI slots for expansion. The vanilla M3A-MVP does not receive the elaborate heat-pipe setup as its deluxe brethren.

Lastly is the value-level ASUS M3A. The ASUS M3A features the AMD RX780 chipset paired with the SB600. The AMD RX780 does not support CrossFire. The ASUS M3A features one PCIe 2.0 x16, three PCIe x1 and three PCI slots.

Expect AMD RD790, RD780 and RX780 motherboards later this year.

PCIE 2.0 but no DDR3 Support?

Just an observation, but it's odd that all these boards support PCIE 2.0 but not DDR3.
Anybody know when AMD is planning to bring DDR3 support to AM2+?

AMD probably won't make the move to DDR3 for quite a while. I assume that they'll make the switch when they move to the "AM3" socket.

I think its code-named AM3 and comes a while after AM2+. The CPUs after Agena/Barcelona (greyhound?) are supposed to have both DDR2 and DDR3 controllers so they can go into AM3 and AM2 boards.

Don't expect DDR3 support until after DDR3 is faster and cheaper than DDR2, in the same way that AM2 didn't happen until DDR2 was cheaper and faster than DDR. AMD likes letting Intel pay the early adopter fees ;)

Well, the performance differance is still small, and I'm currently still on DDR, and DDR2 is cheaper than DDR, and certainly a lot cheaper than DDR3, so for a while, you'll be better of with DDR2, it just more for your money that way.

I think its sometime Q4'2007 or Q1'2008 not sure. I thought i saw that in an article when they were interviewing someone from AMD.

I found the article and here it is.

We asked AMD's Phil Hester when he expects to see DDR3 make sense for the desktop, and he gave us an unusually candid answer. According to Hester, it won't be until late 2008 or early 2009 that DDR3 will make economic sense to move to. Given that Phenom will be DDR2 from the start, it looks like AMD's transition to DDR3 will be much like its transition to DDR2: it will complete well after Intel has made the move.

Current Athlon X2s don't support DDR3. And while I don't remember if K10 does, if it does, they'll release motherboards for it with DDR3 slots.

LOWER LATENCY is usually greater/better than MEMORY SPEED.

Anandtech already had a posting comparing top end DDR2 to recently released DDR3 and the DDR2 system was faster because of the latency of the DDR2 ram.

DDR2 should also make the cost lower to build a machine around. Generally when you buy a CPU you get the equivilent MOBO and RAM to go with the machine.

CPU + MOBO + RAM = New rig guts cost. If you can use readily available DDR2 then the cost would be lower for most to build a machine around that.
