Has anyone run the BYTE benchmarks on a 68020 based system with UNIX
System V yet?? (Motorola guys, are you listening?)

I have a benchmark paper from the Intel literature group which
claims a 6Mhz 80286 is 1.38 a 10Mhz 68010. The 286 machines
were the Intel 286/310 and IBM PC/AT.  The 68010 machines were
a Sun 2/120 and a Masscomp workstation.

Next they determined that a 10Mhz 80286 (0 wait states) is 2.85
times the same 10Mhz 68010 machines. Note these times are all measured
on real machines (as opposed to paper calculations).  The 10Mhz
80286 is also rated as equal to the 16Mhz 68020. The 68020
assumptions were zero wait states and that a 16Mhz 68020 was 2.84
times a 10Mhz 68010 (i.e. no real 020 system).

They finally extrapolate that a 12.5Mhz 80286 (0 wait states)
is 1.27 times a 16Mhz 68020 (0 wait states).

Without arguing the merits of benchmarks, has anyone run any of 
the "common" benchmarks a 16Mhz (or 12.5Mhz) 68020 system?

(For those who haven't seen it, Intel had a two page color
ad about the results mentioned above.  It was is Electronic News,
I believe May 6, 1985. The report I mention  is called "iAPX 286 
High Performance Benchmark Study Report" and is dated April 1985.)
