Let's go into more detail about this.

Please clarify exactly what allows performance gains, if core clock
stays near same order of magnitude?

If cores are currently generally idle then don't we in fact just have
a pipelining/scheduling problem, as opposed to a latency problem?

Yes, the bare metal software environment on the M4 is a bit lame,
but it also does not have a whole lot to do.

What are the actual bottlenecks?
