Very cool, thanks for writing this up. Hard-to-predict access in loops is an interesting case, and it makes sense that AoS would beat SoA there.
Yeah, SIMD is a significant point I forgot to mention.
It’s a fair amount of work to switch between SoA and AoS in most cases, which makes benchmarking hard!StructArrays.jl makes this pretty doable in Julia, and Jonathan Blow talks about making it simple to switch between SoA and AoS in his programming language Jai. I would definitely like to see more languages making it easy to just try one and benchmark the results.
