I think the point of the article is that > memory latency Is actually a hierarchy of its own, and non-linear depending on access patterns. Instruction fetch latency, branch mis-predict latency, cache hit/miss latency (L1 through L3), cache pressure, register pressure, TLB hit/miss, VM pressure, etc. all become significant at scale. Just knowing big-O/big-Ω characteristics aren't enough.
