Benchmark Results: Audio And Video
The current machine’s 3.8 GHz Phenom II is unable to compete with June’s little Sandy Bridge-based processor in iTunes and Lame. This is, of course, a result of great per-clock performance from the Intel chip and two benchmarks that simply do not take advantage of multi-core processors. In titles that aren't threaded, Intel is tough to beat.
Meanwhile, the quad-core AMD chip scores easy victories in the well-threaded HandBrake and MainConcept tests, which benefit more from four physical cores than a pair of Hyper-Threaded cores.
