Asus P5B Deluxe WiFi-AP Edition

Xvid Encoding:

We tested video encoding performance using VirtualDub-MPEG version 1.6.15 and a multithreaded version of the Xvid codec, along with the LAME MT MP3 encoder for encoding audio. We did a two-pass encode of a 15-minute 276MB digital TV recording with a target file size of 100MB.


The Asus out performs the Intel board by several seconds here, probably due to the slight extra memory bandwidth. As expected the two boards equipped with the Core 2 Extreme X6800 trounce the three AM2 boards, despite the Athlon 64 FX-62's far larger memory bandwidth.

MP3 Encoding:

We used LAME MT for our audio encoding test - it's the multithreaded version of the popular LAME MP3 encoder. We ran tests with both Intel's and Microsoft's compilers - naturally, the Intel compiler resulted in some performance increases on Intel's processors. We converted all 18 tracks from Moby's popular Play album to a 192kbps variable bit-rate MP3.


MP3 encoding on the P5B Deluxe board seems to lose out to the Intel D975XBX Bad Axe mobo by a whisker in both tests.


Decoding is a different story with the P5B Deluxe WiFi-AP Edition coming out as the fastest of all boards tested by at least a few seconds.
