For interests sake, I benchmarked a S-100 machine with an 8 Mhz 8086 using
the Harmonic series benchmark proposed a few articles ago. Using Microsoft
C Version 3.00, I got:

          9.787613 using float and it took 13 seconds
          9.787606 using double and it took 14 seconds

I took out the CPU board, lowered the clock rate to 5 Mhz and plugged in the
8087 floating point processor and reran the benchmarks.  It gave the same
results and took less than 1 second in each case.  Although these times
(even the software floating point) are faster than the Mac with a 8 Mhz
68000 (Using C), it doesn't mean that for the same clock speed that the 8086
is faster than the 68000 but rather that Microsoft did a better job in
implementing the floating point on their C compiler.
