The perl benchmark suite. This is a single-threaded test with two subtests listed. The second test is much more interrupt driven than the first.
Topdown profile also shows differences with the first benchmark having a high retirement rate and the second having a high frontend stall rate.
AMD metrics are a composite of two workloads. Overall floating point is low as is L2 access.
