Rather (Pres. of Forth Inc.)is reported by Electronics magazine as: Rather says the results are surprising because, until the tests were completed, "we all thought the 68020 was faster." : Every benchmark I have read in print has either been : tampered with by the introduction of bugs in one or the other side to : favor one particular view, or depends entirely on the quality of : whatever compiler/interpreter is being used in the benchmark test. : : In this case, I would guess that a close look at the Polyforth : implementations on both machines would disclose certain inefficiencies : that work out to favor the 386. From such a comparison we can deduce : very little about the performance of either machine; only of the : Polyforth implementations. : Are we supposed to take seriously the suggestion the Forth would not optimize the most critical part of their system for each processor? Remember that Forth lets you get down to specifying the actual machine instructions for critical code as was probably done here so these results presumably give a better measure of the chip performance than the typical C or Fortran program which is dominated by compiler quality.
