PyPerformance is the reference Python performance benchmark suite. It takes approximately 20x longer to run than pybench benchmark.It is however still single threaded. There are 13 subtests below with slightly different profiles and a few that are interrupt driven.
Topdown profile shows slight differences among the 13 workloads with most having high retirement rates but then some backend stalls and frontend stalls.
AMD metrics are a composite. This is still a workload with little floating point.
