Gene,
Actually some operations will run at even more than double the
speed, but many operations will not so the average increase, as indicated
by Jez San's speed program masks areas of big difference. I have a
Hurricane H2000 with a 14 Mhz 68020 and a 20 Mhz 68881. Speed indicates a
1.32 increase over a stock 68000. However, various other benchmarks
indicate increases from as little as 10% to as much as 1000%! Imtronics'
benchmark indicates an increase of 1.9 over a stock 68000, while floating
math operations may be 10 to 15 times as fast. If I turn the cache off,
then the benchmarks show anywhere from a 10% decrease to a 20% increase
over the stock 68000. Be careful of claims!!! Remember that the CSA
midget (I think that's what you were looking at) still runs at 7 Mhz, so
you get mainly the benefit of the faster internal processing and that's
about it.
