I don't think memory is the issue. Hash algorithms are just complicated math. This math is now targeting the CPU architectures themselves.
It's easier to make it faster to write it in assembly were you can hand tune all the instructions when you are already thinking that low level.
Perhaps not a concern for Blake, but timing attacks are real. It you need to make your function operate constant time then your compiler is likely working against you.
