What Intel loved more was hiring Chuck Moore to teach hardware
design classes to their engineering staff and to license some
of this patents to make their chips perform better. I don't
think Intel competes in the $.10 processor market or cares
much about it.

Well sure.  But to be fair and not do too much watermelon
to grape comparisons one should pick a 100KHz four-bit CMOS
chip for comparison to a c18 or about 300,000 c18 to compare
to a big Intel chip.  Plus c18, like Forth itself, shines
best on integer math not floating point and was not designed
for floating point.

The biggest differences beside thousands of times difference
in cost and power usage in your comparison would be on
real-time and embedded application where the deep pipelines
and multi-level caches make the big chips lose terribly
on performance when interrupts or context switches take
unpredictable amounts of time that may vary by hundreds
of times in speed.

The important thing with the freight train is that they
can haul a lot at high speed for their cost even it they
take an hour to get up to speed or slow down for curves.
The important things with the small stuff is low cost
and low power and the agility and ease of programming
that comes from being small and simple.

If you think a multi-thousand dollar multi-watt chip
would be good for low cost, low power agile applications
you don't understand them.  If you think a tiny chip
with minimal cost and power usage would be good for
hauling a hundred freightcars of coal you don't
understand them either.  The biggest conceptual
problem for understanding embedded processing is
people with only exposure to desktop computing
methods.

P.P.S and that's also why big CPUs have cost as much as $3000 each
in lots of 5000. Many chips today to use multiply step instructions
rather than full one-cycle multiply circuits that might be much larger
than the rest of the chip.

And Forth has a forty year history of showing how floating
point was not needed in many of the places where other
programmers assumed that floating point was needed.  I have
used floating point outside of Forth.  In my twenty-five
years of professional Forth programming I have never needed
to use floating point for anything.  Chuck has not had to
use floating point for anything in the last twenty-five
years.

Best Wishes
