Benchmark Results: Audio And Video Encoding
Apple iTunes is almost exclusively limited to what a single core can achieve per clock cycle, and it usually reflects that limitation in our benchmark chart.
Lame’s similarity to iTunes in today’s tests is most likely due to the use of the same Intel Core technology in all three builds. We’ve seen evidence of at least some optimizations when comparing other, more diverse hardware.
In comparison, HandBrake and MainConcept are multi-threaded, rewarding the $1000 and $2000 machines for their quad-core technologies.
