Appleseed is a rendering engine with three workloads taking almost 100% of the CPU
Overall topdown shows backend stalls dominating but each workload with slightly different profiles particularly the amount of frontend/backend stalls.
AMD metrics grouped together summary shows floating point code with moderate number of branches.
