Encode-wavpack is one of several quick-running encode benchmarks. These are quick-running high-IPC programs with just a few threads. In this case, single-threaded code with just two in the run queue.
Topdown overview shows a high retirement rate though slightly lower than encode-{flac,mp3,opus with more backend stalls than these other workloads.
AMD metrics shows low on-cpu and this is integer code not floating point. It shows
