System Builder Marathon, Q1 2014: Our New Enthusiast PC

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.

Running on a single core, the first two benchmarks fare worse on the new build, despite its higher Turbo Boost clock rate. It's possible that more conservative memory settings are limiting performance in stock form. That hypothesis is backed up by the Q1 machine's slight win in overclocked trim once XMP is enabling, bringing throughput back up to where we want it.

In sharp contrast, HandBrake and TotalCode Studio are highly responsive to Hyper-Threading, giving the new build a significant advantage over the Core i5-4670K we used last time around.
