Benchmark Results: Audio and Video Encoding

System Builder Marathon: Performance & Value

Apple iTunes doesn’t appear to be optimized for any particular processor (specifically, anything more than dual-core processing), so its performance is based almost entirely on clock speed.

The results for Lame MP3, the only other audio encoding benchmark in our suite, also reflect clock speed more than any other factor.

TMPGEnc has favored faster memory throughput for as long as most of us can remember, but when it comes to specific codecs, DivX appears better-optimized for quad-core processing than Xvid.

Mainconcept takes full advantage of the Core i7 architecture in this month’s $1,250 and $2,500 machines.
