This can be easily deduced from the performance of Intel's RapidCAD chip which is basically a 486 without the cache and with a 386 pin out. While the RapidCAD offers roughly twice the floating point performance of the Intel 387DX, my benchmarks showed it to be at most 25% faster than the 80386. Typical performance gain for integer applications is more like 15% though. This definitely Hmmm.. a local salesperson told me last May that this RapidCAD would give up to 70 % more performance for both fp and int operations and that the average gain is much less than 50 %. These numbers are agaist a separate 386 & 387 system (with same clock). I have not tested it. maybe he just tried to sell me on over expencive 486 motherboard....... -- Timo "I am logged in, therefore I am" Suhonen "There is no need for the President of the United States to be smart" -HST Opinions(?) are mine (if not stolen), NOT those of Univ. of Jyvaskyla.
