I think you're right. I have seen benchmarks (from Intel, of course :-))
where an i486/33 were faster than an R3000... Have they measured nops ?

Anyway, the FPU-version of the R3051/2 called R3081 doesn't have more
cache, so far I know. And I don't think that it's faster than
a R3000/3010 combination with the same clock. The architecture is
exactly the same, only on a single die.
