Both LAME and iTunes are used to convert audio files from one format to another, and neither test is threaded. Consequently, Intel's Core i5-3570K does notably better than AMD's FX-8350 thanks to better performance per clock cycle. Access to unconstrained overclocking propels the Ivy Bridge-based chip even further ahead in both benchmarks.
Unlike the audio transcoding workloads, our video-oriented conversions, HandBrake and TotalCode Studio, are heavily-threaded. These demonstrate an advantage for AMD's module-based architecture at stock clock rates. But Intel's i5-3570K has much more room for overclocking, and manages a slight win in both categories when tweaked.
