Benchmark Results: Audio And Video Encoding
Poorly-threaded applications like Apple's iTunes generally respond to CPU frequency more than anything else.
Credit goes to the enormous Prolimatech Megahalems CPU cooler for allowing the overclocked $2000 machine beat its less expensive rivals.
HandBrake stands in stark contrast to iTunes, pushing every available core to 100% of available resources. The $2000 PC picks up it biggest win here, while the $500 triple-core configuration appears to beat the $1000 machine’s four logical (two physical) cores, clock-for-clock.
TMPGEnc falls between iTunes and HandBrake, getting little benefit from added cores and greater benefit from increased CPU frequency.
Professional applications generally use CPU resources most effectively, and MainConcepts benchmark results are a perfect reflection to those of HandBrake. The overclocked $1000 PC barely edges past the overclocked $500 system, while the $2000 machine’s four cores allow much larger performance gains.
