    Eh, as always: It depends.

    For example: memcpy, which is one of their claimed 100x performance tasks, can be IO-bound on systems, where the CPU doesn’t have many memory channels. But with a well optimized architecture, e.g. modern server CPUs with a lot more memory channels available, it’s actually pretty hard to saturate the memory bandwidth completely.
