It seems to me the MIPS 55 MIPS (@ 60 MHz?) ECL system (chip set?)
is the "classical" approach for RISC designs to get higher through-
put. They do it by upping the clock-rate.

Intel has gone the SuperScalar route. Their i960CA is said to be
66 MIPS @ 33 MHz. They have put the cleverness into multiple
execution units.

Here is the $64,000 question:

   Which part is easier to integrate into a real system? 

Please note that we have concrete real examples here. Theoratical
discussion is nice, but real data-points are more interesting.

Other interesting question:

   Which system has a larger "domain" over which it actually
   achives quoted figures?

   What other systems/chips/... are claiming over 50 MIPS?

   How do these systems compare in terms of cost (design and per unit)?
