A few more links for low level CPU benchmarking

2 - https://reflexive.space/zen2-ibs/ how to capture per micro op data on AMD >= Zen 1 CPUs

I agree on "it depends". And usually not only on your actual code and data, but also how you arrange it over cache lines, what other code on the same core/complex/system is doing to your view of the cache and some other internal CPU features like prefetchers or branch predictors.
