Hi,

 

I have posted a question on Stackoverflow and I thought I would share it here as well:

 

https://stackoverflow.com/questions/70668229/same-compute-intensive-function-running-on-two-different-cores-resulting-in-diff

 

What could be the root cause for this confusing behavior on different microarchitectures?

 

Thanks
