Asus A8R-MVP: Mainstream Rocket

Audio Performance
For audio testing, we used Rightmark 3D Sound CPU utilization test, which is the same benchmark run in our earlier nForce4 SLI and Ultra roundups. This benchmark measures the overhead or CPU utilization required by a codec or hardware audio chip. We tested performance using the latest version 2.1. Since we found that Version 2.1 yields different results from the earlier 1.24, we have only included test results with version 2.1.
It is very important to point out that the 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.
Ethernet Performance
The one area where the Asus A8R-MVP is mildly disappointing is in their choice of an Ethernet controller. Instead of using a PCIe LAN that is capable of providing full 1 Gb bandwidth, Asus used a PCI solution that will be limited in maximum speed by the PCI bus. In practical terms, the PCI bus caps out about 700 Mb/s compared to the 950Mb/s capability of a 1 Gigabit PCIe solution. Since most broadband Ethernet connections barely tax 10Mb/s, this really only matters to those who do sustained high-speed transfer of very large files over a true 1Gb network - probably less than 1% of users. Still, you should be aware that PCIe Gigabit Ethernet is always a better solution.
The Windows 2000 Driver Development Kit (DDK) includes a useful LAN testing utility called NTttcp. We used the NTttcp tool to test Ethernet throughput and the CPU utilization of the various Ethernet Controllers used on the AMD motherboards.
We set up one machine as the server; in this case, an Intel box with an Intel CSA Gigabit LAN connection. Intel CSA has a reputation for providing fast throughput and this seemed to be a reasonable choice to serve our Gigabit LAN clients. At the server side, we used the following Command Line as suggested by the VIA whitepaper on LAN testing:

None of the onboard audio solutions were quite as low in CPU utilization as the hardware Creative SoundBlaster Live! chip, which we have tested on both AMD and Intel top-end boards from MSI. However, ATI's High Definition Audio on the ADI Soundmax used in the Asus produced excellent performance in all the utilization tests. Results were in every case almost as good as the hardware solution. Azalia HD is apparently more demanding of CPU power, but CPU utilization remained below 5% even in 3D audio rendering as tested with RightMark 2.1. While we have not reported 3D + EAX comparative results, we did run this test and found CPU utilization of just 6.11% for this demanding audio test.

Ntttcps -m 4,0,‹client IP› -a 4 -l 256000 -n 30000On the client side (the motherboard under test), we used the following Command Line:
Ntttcpr -m 4,0,‹server IP› -a 4 -l 256000 -n 30000At the conclusion of the test, we captured the throughput and CPU utilization figures from the client screen.
As you can clearly see, PCIe Gigabit LAN is capable of about 35% faster speed than what the PCI Gigabit LAN used on the A8R-MVP. In practical terms, this won't matter to most users, since high-speed internet barely taxes a 10Mb/s connection. The speed difference may be important if you routinely transfer many large files on a full 1 Gigabit network.

thanks for clarifying.:) guess it's best to wait and see other reveiws to get a general consensus though.Calin - Wednesday, November 23, 2005 - link
Maybe the design team had a set of design cues for the board, received from the top (management) - these include cost, performance, reliability, and possibly even other metrics. The ATI chipset might have been too good for those cues, or maybe they worked to optimize the board - and told nothing to management about their substantial successes.Or maybe the board was a lucky one, and maybe 1 in 100 will get near those results, and the rest will be mainstream. Anyway, I think it is a good design, and not a lucky board

Hi Wes, Did you run into any coldboot problems ?Wesley Fink - Wednesday, November 23, 2005 - link
No Coldboot problems at working overclocks. We did find, however, that failed overclocks at very high frequencies usually required the system be turned off (power switched off) for the board to recover from the failed OC. This is common to many motherboards, but it is always easier if the board recovers on a warm boot.Diasper - Wednesday, November 23, 2005 - link
Just wondering why there weren't any game benchmark comparisons against the Asus A8N32 given the article set out by comparing them and given the numerous benchmarks with it including Aquamark, how come it was excluded from the rest of the game benchmarks?? It would be pretty nice/important if you included them.nvidia4ever - Wednesday, November 23, 2005 - link
I was wondering the same. Either the results are not favorable for ATI or there are results coming that were not posted yet. Either way it looks like a great board.Wesley Fink - Wednesday, November 23, 2005 - link
The original benchmarks with the A8N32-SLI Deluxe were run at 1600x1200 with AA/AF on. This is because we were trying to determine if Dual x16 SLI made any difference compared to Dual x8 SLI. When we tested the ATI we reran benchmarks on one of the current top nForce4 boards - the DFI LANParty nForce4 SLI - to provide a comparison with the nForce4 SLI chipset. We did not have the Asus A8N32-SLI available for retesting since another reviewer was using the board for benchmarking. It also didn't seem important to also rerun benches on the A8N32-SLI since its performance was comparable to the DFI nF4 SLI.At any rate, the A8N32-SLI is available again and we will rerun some benches at 1280x1024 and add results to the game graphs. For "Standard Score" benchmarks like 3DMarks and Aquamark 3 the video resolutions are always the same and the A8N32-SLI results are already included in the graphs.

It was pretty obvious a year ago that ATI had created a very impressive chipset for the AMD Mobos. The Southbridge ULi chip resolves perceived deficiencies by those who believe they need faster USB and S-ATA 2, even though in reality this simply isn't true. The fact that the ATI Northbridge chipset O/C's so well is proof of an excellent design and one to build a Helleva reputation on in the Mobo market. The ATI chipset makes it pretty obvious that you don't need to endure high prices and marketing gimmicks of some Mobo mfgs. to promote over-priced "gamers or overclockers" Mobos that don't deliver as much, let alone more PC performance than the ATI chipset Mobos, which include all the practical overclocking BIOS options anyone would possibly need.sunshine - Wednesday, November 23, 2005 - link
RE: "Our first efforts at overclocking the A8R-MVP ran into a road block at just over 260. We have found some Asus boards in the past that did not like overclocks to be immediately set to high values, so we started again at 250. By going up just 5 to 10FSB at a time, we were able to reach 325."What is it exactly that prevents you from setting up the overclocking settings all at once? Why must you increase at only 5 - 10 mhz at a time? Is the Asus Bios boobytrapped to prevent someone from frying their motherboard or CPU???
