This is actually quite close.  I can't speak to floating point
performance, but a 486-50DX EISA machine with a 256k memory cache will
usually hit right around 21 MIPS.  This might actually outperform a
SPARC 2, which has a similar MIPS rating but is a RISC processor
(hence MIPS don't quite compare to MIPS on a CISC processor like the
i486).  The only place I would expect a SPARCStation 2 to radically
outperform it is for graphics.

[By the way, a SPARCStation 2 is a Sun 4 (as is a SPARCStation 1+,
which is what the IPC is).  That's why I changed the subject.]

I thought their tests were somewhat biased beforehand, since they
weren't measuring anything like the same thing on each machine.  It
amounted to "how fast can I run PC-type applications on this machine".
