Signal processing blocks for software-defined radio. There is one result but it reports on six subtests. The later ones look single-threaded with earier ones have more multi-threaded aspects.
Topdown profile shows variation amount the subtests with a few backend bound and a few with high retirement rates.
AMD metrics are a composite. This is floating point code with moderate retirement rate.
