ARM and Intel have different performance characteristics: a case study

In my previous post, I reviewed a new fast random number generator called wyhash. I commented that I expected it to do well on x64 processors (Intel and AMD), but not so well on ARM processors. Let me reuse my benchmark where I simply sum up 524288 random integers are record how long it takes…

According to my tests, on the x64 processor, wyhash is five times faster than splitmix.
