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.
Here the SD37P2 is only a fraction slower than the 975X/G, despite the memory speed difference. Both are over two minutes faster than the Asus.
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.
Using the Intel compiler of LAME, the SD37P2 performs slightly faster at encoding than both other systems, but sits between them at decoding. The difference is somewhat indistinguishable, however.
