Ah, I see.  I was mixing up the A7 with the A8.

Not sure I believe that, given memory latencies, but then if the memory
subsystem is better, perhaps it compensates.  (Routing in software is not
a cache-friendly endeavour.)

Still 20 times larger than a PDP-8 ;-)

Thanks for the info, Jonathan.  With the FCC lockdown, we're going to have
to learn all that stuff (and more) if we want hackable hardware.
