Remarks:

* Whetstone/Dhrystone are 32-bit DOS results
+ SPEC ratios recomputed from SPEC timings (computed wrong in report)
& note huge increase in SPEC floating point performance over previous results
  due to new experimental FORTRAN compiler
# machine with AMD 386-40/Cyrix 83D87-40/128 kB cache is estimated by me at:
  7.7 SPECint, 4.5 SPECfp, 5.8 SPECmark,
  5000 double prec. Whetstones, 23000 Dhrystones,
  0.6 Linpack double prec. MFlops
  These estimates based on my own measurements and data from:
  FasMath 83D87 Benchmark Report, Cyrix 1990

  AMD 1991
