Yeah, and in the blog post he mentions that he had to transform the data to SoA. If he had done that alone, he might already have seen a speedup from better cache utilization.
Also, I see no mention of alignment in the post. I understand x86/AVX2 likes your load/stores to be aligned, even if it technically allows unaligned access.
