386 performance vs 486It also helped that a fast 386 could keep pace with the slowest 486s. The 40 MHz version of the Am386 enjoyed an especially long shelf life as a value CPU. The 486 was more efficient than the 386 but it wasn’t twice as efficient, so a 40 MHz 386 was faster than a 20 MHz Intel 486SX, and roughly comparable to a 25 MHz 486SX. It also held the additional advantage of taking an external math coprocessor. Part of the point of the 486 was the integrated math coprocessor improved performance, but an external math coprocessor was faster than none. So while a 40 MHz 386 plus a 40 MHz 387 wasn’t as fast as a full 486DX at 25 MHz, depending on whose FPU you used, you could get 75-90 percent of the performance at less than 75 percent of the price.
