Benchmark Results: Audio And Video Encoding
The G51J’s improved-efficiency mobile Core i7 nearly matches the D900F’s desktop processor in iTunes encoding. A low clock speed hampers the Core 2 Quad-powered GT725.
The G51J falls further behind in Lame, but significantly outpaces the GT725’s older technology.
Intel Turbo Boost and DivX aren’t happy together--the G51J’s maximum four-core active clock of 1.73 GHz falls behind the 2.0 GHz clock of the GT725 in this eight-thread application.
The G51J looks a little better in MainConcept, but there’s no perfect substitute for the D900F’s desktop-based prowess.
