This test looks like a variation of the stream benchmark with copy/scale/triad and average. It uses floating point and integer data types. It looks to be mostly one or two threads.
Topdown profile shows a backend bound program
AMD metrics confirm this as memory bound with high rate of L2 access. Despite moving floating point, there are almost no floating point intructions.
