The LINPACK performance table can be obtained by sending to netlib@ornl.org
a message saying:
send performance from benchmark

Here is what I found:
CDC Cyber 2000V 32 Mflops
CDC Cyber 205(4-pipe) 17 Mflops
CDC Cyber 205(2-pipe) 17 Mflops
CDC Cyber 990E 12 Mflops
CDC Cyber 4680 9.4 Mflops
CDC Cyber 875 4.8 Mflops
CDC Cyber 176 4.6 Mflops
CDC Cyber 760 2.6 Mflops
CDC Cyber 175 2.1 Mflops
CDC Cyber 180-860 2.1 Mflops

The first 486 listed is
Compaq Deskpro 486/331-120w/487  1.4 Mflops

You can get the benchmarking program and run it on your machine.
