PiFast

A good indicator of CPU/Motherboard performance is PiFast version 4.2, by Xavier Gourdon. We used a computation of 10000000 digits of Pi, Chudnovsky method, 1024 K FFT, and no disk memory. Note that lower scores are better, and times are in seconds.

The K7N2's superior memory performance over the AN7 edges it out in front in this test, although once again the difference is minimal.

VirtualDub Audio Extraction

We ripped the audio of at 44,100Hz, no compression using VirtualDub 1.5.8 (Build 18068). Times are in seconds, and lower is better.

The numbers are as expected here, as this kind of test is dependent on many factors, from your hard drive to CPU speed as well as memory. Using the same hardware across the board the AN7 shows itself to be more than capable of keeping up with the rest.

TMPGEnc 2.521

We will encode a 150mb AVI file to MPEG2 (a somewhat realistic chore as DVD's are MPEG-2). For the AVI to MPEG-2 I used a bitrate of 5000k/Sec, as this is the midrange for a DVD, which is typically between 1000k/Sec to 10,000k/Sec. I used a frame size of 720x480 (DVD Std) and 16:9 NTSC. Note that lower scores are better.

Once again the extra memory performance from the allows the K7N2 to gain the upper hand by a few seconds, quite a few in fact.

Gaming Tests

UT2K3 is a real system killer and can bring many systems to its knees. We used the [H]ardocp UT2003 Benchmarking utility version 2.1, which are excellent tools in testing various resolutions and detail levels. We selected the CPU test, which uses the dm-inferno map. We also used our own in house CPU tests for Call of Duty and Quake III Arena, which use the game's low detail and low resolution defaults.

For gaming the AN7 can keep up with the rest of the crowd without issue, putting out the numbers we expect it to as well as a healthy boost from the overclocking.
