I believe that the standard Intel answer is that the 486(TM) is about 1.5 to 2x faster than a 386(TM) at the same clock rate, depending on code and system blah blah blah. The math tends to run about 4x of a 387(TM). Intel has SPECs, but I've never seen them. The best thing to do is to bench your own code on the machines that you would use. That's about the only useful benchmark that I've ever seen. Greetings from the rocking metropolis. Jimf
