you should try running Linpack on them all (you can find the results here mixed in with other machines I own) https://web.eece.maine.edu/~vweaver/group/machines.html

When I did that on Pi3 when it first came out you could crash the system because the thermal throttling wasn't fast enough (the temp sensor was on the GPU not CPU). When I reported the issue on the pi forums the answer was essentially "why would anyone ever want to do that"
