3D CAD modeler program. There are five different workloads. From the profile, these look to be single-threaded with something extra running during the first workload. The relative times also stand out with first workload taking almost as much time as the other four combined.
Topdown profile shows a high retirement rate and mix of backend and frontend stalls.
AMD metrics reflect a low on-core percentage, ~1/5 instructions are branches and very little floating point.
