Abit KN9 SLI

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 Xvid encoding test produces a very fast time on the Abit KN9 SLI - it was faster than every other socket AM2 board tested, but was slower than the Intel reference board, as a result of Intel's rather speedy Core 2 Extreme processor. Enabling SLI only resulted in a two second increase in encoding time.

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 and decoding is generally faster and is one of the fastest boards we've tested. Decoding is weighted to hard disk write speed moreso than CPU and memory capabilities, but a faster CPU does help somewhat.
