MSI announces its first RD790-based board

MSI today announced its K9A2 Platinum Motherboard based on AMD’s RD790 chipset, officially dubbed the 790FX. The 790FX serves as AMD’s primary single and dual-processor platform and replaces AMD’s antiquated 580X chipset. The new MSI board comes with support for a host of new features, including support for AMD quad-core processors and Crossfire X.

The K9A2 Platinum supports all AM2+ processors, which means it will work with AMD’s upcoming Phenom quad-core, tri-core and dual-core desktop processors. Existing AM2 processors are also supported by the newest board BIOS.

The 790FX also brings 41 PCIe 2.0 lanes to AMD’s AM2+ platform, allowing manufacturers flexibility in the number of PCIe slots integrated on the board. The K9A2 comes with four PCIe 2.0 x16 slots and supports AMD’s Triple-Play Technology. In addition, MSI goes a step further by offering Quad Crossfire capability on the mainboard. 

As of right now, AMD has not officially launched Triple-Play technology. MSI indicates, however, the official debut should take place soon. AMD guidance claims ATI RV670, Phenom and RD790 will simultaneously launch together next month.

It should be noted for clarity that those four x16 slots have x8 signaling.

Yes but these are PCI-E 2.0 slots so they have double the bandwidth of PCI-E 1.1 In effect they are just as fast as 4 x16 slots.

It is a shame they did not link to the new ATI's budget RV670 coming out soon with 55 process and very good clock speed making it very possible that this could be the performance champion if they get the drivers worked out for quad crossfire.

I'm not sure I want a world where we all have to buy 4 overpriced graphics cards to run games properly.

actually, at 55nm and one card slot, they will be far cheaper to produce. Following AMD's current business model, I'd say we will likely see a few are very competitive price points (the new G92 is still on 65 nm, and the G90 is on an 80nm process). I would expect to see a new revision with for more aggressive clocks in the core which could push ATI over the Nvidia hump

4 x $250 is a lot to pay, but compared to buying two 8800 Ultras, it's actually a bargain!

For the rest of us, 1 or 2 RV670s should be enough!

I don't think the world will come to that (needing 4 gfx cards just to play a game). For one thing, studios like id and valve go out of their way to make their games accessible to low end/mid-range gamers.

that is, until power consumption eats up your wallet.

way too few people ever take power consumption into the equation. Looking at the upfront cost is inadequate if they're going to be using the same system for a couple of years. For those who leave their systems running 24/7 this is even more of a problem.

assuming dual crossfire alone idles at 200W+ when paired with a quad core proc, and can break 400W when under stress, a quad-crossfire setup could easily require 300W+ just idling, and shoot past 500-600W under load.

I've never noticed the power consumption of my two computers in my electric bill. It just doesn't make ANY difference in my household. Running the A/C in August or filling the propane tank is what makes my wallet sore.

that's because computers are used year round, and thus are part of the "background" electric consumption. try going one month without turning on the comps and you'll definitely see the difference.

I'd take average computer power consumption = 250w, display included.

You'll need to run it for 4 hours to use 1 kwH. That's like, what, 8¢?

That's $14.4 if run continously over a 30 day month. If you turn off your display when you sleep / not there, it would be less/make up for the higher consumption when gaming.

Only if you use a PCI-E 2.0 graphics card in them.

I didn't say the slots aren't fast, or even that x8 signaling is bad did I? I said it should be noted for clarity that the physical x16 slots use x8 signaling. As someone else pointed out, you only get the PCIe 2.0 speed with a PCIe 2.0 card, of which there aren't any yet.
