The Alpha 21264 is much faster than an Intel 400 MHz if you compare
non-optimized C code (FORTRAN like code with big arrays of global data). But
if you compare a well-written C code on the Alpha (who write in assembler on
this chip ?) with a code in assembler on the PII/400, the Alpha is faster
(not much). If you take into account the number of PII that you can buy for
the price of one Alpha 21264, a set of PII is faster if the computation can
be distributed.
The MIPS R10000 is an "old" processor and is not fast today. I have some at
office and tested my FFT-multiplication on it. A R10000/250 is about as fast
as a PII/333. The R5000 is about 2 times slower.

It is based on a R3000. It should not be faster than a 486 or a Pentium 75.
