Asus A8R32-MVP Deluxe: First ATI RD580

Audio Performance
For audio testing, we used the latest version 2.2 of the Rightmark 3D Sound CPU utilization test. This benchmark measures the overhead or CPU utilization required by a codec or hardware audio chip. Versions earlier than 2.2 would not work properly on the RD580 chipset based A8R32-MVP.
Realtek has been very consistent in recent months in releasing regular updates to their HD audio drivers, and we suspect that trend will continue, with ATI and Intel both firmly committed to HD and NVIDIA also introducing hew HD solutions. Each new Realtek update has lowered CPU utilization and we also hope that will continue.
ATI chipset motherboards have the necessary hooks to deliver Azalia High Definition audio. Those who have been complaining about the poor AC’97 audio present on most AMD boards should be very pleased to find Azalia HD on the ATI chipset boards. The nForce4 family does not offer the necessary chipset hooks to support HD Azalia audio on their top Athlon 64 chipsets. However, recent introductions by NVIDIA have included the HD audio option and we expect future NVIDIA chipsets to offer this feature.

The High Definition audio codecs have generally shown lower CPU utilization in audio benchmarking than earlier AC’97 audio solutions. The Empty CPU and 2 D audio both showed extremely low utilization scores in the 1 to 3% range. However, 3D audio on the Realtek ALC882 was around 9% - far from the 30 to 40% that we have seen in the past, but still enough to steal a few frames-per-second from games. It is worth mentioning that the even more demanding 3D Audio+EAX test showed a slightly lower 8.82% CPU utilization

This doesn't make sense: "there will never be another Asus product purchased by our company". Why would a business care about overclocking? A business should care about STABILITY.DigitalFreak - Friday, February 17, 2006 - link
They should have moved the only PCI-E 1x slot to the left. They way it is now, you lose that slot when using a dual slot cooler in the PCI-E 16x slot closest to the processor. Hopefully that will be changed on the AM2 version of the board.aguilpa1 - Friday, February 17, 2006 - link
a 7800 and 1900 this way we can better gauge the mean performance of the "board" with identical comparison to other previously tested boards because not everyone is going to run out and get a $600 1900 ATI just for this board.Wesley Fink - Friday, February 17, 2006 - link
We DID test the A8R32-MVP with both the X1900XT and the 7800GTX. If you closely at the standard gaming performance graphs on p.9 you will see the orange bars are the A8R32-MVP test eith the X1900XT and the green bars are the same A8R32-MVP tests with the 7800GTX. The other board results are with the 7800GTX so if you compare the green bar to all the blue bars you are comparing 7800GTX performance on ATI and nVidia. In addition, all the bars are labeled with the test board and test video card to prevent confusion.This is explained in Test Setup on p.6, and in my comment above, "We reported both results so you could compare 7800GTX performance to the previous boards also tested with the 7800GTX. Since the X1900XT is the latest and fastest video card the results were included for Reference only. As someone else pointed out, when testing Dual X16 Video you have to run SLI on nVidia and Crossfire on ATI (or Intel)."

never mind, I see someone asked the same question, but were not given a reasonable answer anywaysBPB - Friday, February 17, 2006 - link
This is exciting news. But I plan on getting the X1900 AIW, which won't do Crossfire. So, when are we going to see non-Crossfire (Xpress 200-type) versions of this chipset? In the end I may get this board, but I'm hoping I can save a few bucks by getting one without the added cost of Crossfire.Wesley Fink - Wednesday, March 1, 2006 - link
RD580 is only available as the dual x16 version. With both x16 lanes off the north bridge you can't really leave out a chip, as you can in the nVidia version right now, and lower the price. The single X16 slot and dual x8 Crossfire will be provided by RD480.n7 - Friday, February 17, 2006 - link
Looks like a superb motherboard for the price!Zebo - Friday, February 17, 2006 - link
Look perfect to me. Black, high clocker, built like a tank and relativly inexpensive. I wish they had this two months ago - U seen my DFI chipset mod what a PITA to get silent chipset sitting right under card.:( Not only is ATI chispet seemingly cooler leaving us with passive solutions they clock at least as well if not better.Zebo - Friday, February 17, 2006 - link
Also the gap between PCIe cards is perfect to run water blocks too and well as nV/ATI silencers w/o touching or being cramped..
