This workload tries the BYTE magazine benchmarks. There is one test which reports a “LPS” score and is labeled Dhrystone2. Topdown metrics show this is single-threaded
Topdown profile shows a high retirement rate and low backend stalls.
AMD metrics show little floating point or L2 access. The retirement rate is high and backend stalls are low.
