XMPEG and Lame - Audio and Video Encoding



A strong suit of the P4 has always been media encoding, ripping audio files to MP3 and encoding or converting digital video.  In that vein we have our Lame MP3 and XMPEG - DiVX encoding tests, which should bode well for the Asus P5AD2-E.

Benchmarks with XMPEG / DivX v5.2.1
Video Encoding Performance


Here the highest clock speed P4 3.6GHz systems take the lead again and the Athlon 64 is left in the dust.  Interestingly enough, the Intel i925XE motherboard just slipped by the P5AD2-E in flat out photo finish.

LAME MP3 Encoding Tests: Single & Multi-Tasking
Converting a Large WAV To MP3

In our custom Lame MP3 tests, we convert a largo audio file to the MP3 format, which is a very popular scenario that many end users work with on a regular basis.  In this test, we chose a large 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format. Processing times are recorded below. Shorter times equate to better performance.

The P5AD2-E is right in line with the reference Intel board when configured with the same 3.6GHz P4.  However, when we plugged the 3.46GHz EE P4 into the socket and set it up with a 1066MHz FSB, we picked up a full 9 seconds in processing time, most likely due the P4 EE's larger 2MB L3 cache and higher FSB.
