Benchmarks II
Next we'll turn our attention to MP3 encoding. We're benchmarking by encoding a 638MB custom WAV file (Moby's Play album, incidentally) into 192kb/s MP3 using the LAME 3.92 encoder and Razor-Lame 1.15 front-end.
WAV encoding, no lover of bandwidth on offer, simply takes to the processor with the fastest FPU. The 1.73GHz Athlon XP is able to oust the Pentium 4 2.26GHz again.
Another media-related task that many of us indulge in is DVD - DivX encoding, I certainly have been doing a great deal of late. Once again, I've changed my benchmark suite to something I feel better reflects true performance.
I'm now using a quality-driven approach. 2-pass encoding via VirtualDub. Three Kings is the DVD of choice, resized to 720x304, precise bilinear and black borders cropped. YUV2 spacing is used and the bit rate is set to 1700 kbps. I encode a 15-minute section and calculate the average fps from there. DivX 4.12 is still my benchmarking CODEC of choice.
More of the same here.
