The RTX-2000 was an of shoot of the NC4000. Even at 10MHz, they could
out compute a 40MHz 80386.
One execution per clock cycle plus possibly using 3 16 bit busses in a single
cycle.
A 4MHz NC4000 could sort 1K 16 bit values in 19.7 milliseconds.

I hadn't even heard of that chip :/

I never had much run in with these kinds of boards as they were geared
toward very specific markets. However, the Intel i860 and i960 did make it
into some consumer level boards. I have a MCA SCSI RAID Controller somewhere
that uses an i960 for coprocessing... Of course that may be a bit too new
for CCtalk....
