The following audio- and video-oriented transcoding benchmarks are tied to processor performance. There are definitely differences in how they utilize CPUs with multiple cores, though. Our iTunes and LAME tests employ a single thread, giving us a good look at the per-core performance of each CPU. Meanwhile, TotalCode Studio and HandBrake leverage as many cores as they can get.
With identical CPUs at identical stock clocks, we didn't expect to see any changes here, and we didn't.
HandBrake and TotalCode Studio are highly responsive to a jump up to four cores, and then the addition of Hyper-Threading support. Regardless, there's not much of a difference between these two systems.
