It is not my understanding that Intel hardware generally beats ARM in these categories. Not the person you replied to, but this could have a couple interpretations where Intel wins. Here's one option: If you take two CPUs with similar core counts, clock speed, and transister counts then which one will have higher throughput, lower latency, ... for typical operations? This is open to interpretation of course (e.g. if you didn't need floating point throughput then AMD bulldozer architectures were competitive when released), but it's not unreasonable to evaluate CPUs based on your personal workloads.
