The answer depends [obviously] on how much flaoting point math is really
performed.  As a point of comparison I offer the following --

	25MHz 80386DX - NO coproc runs *my* WHETSONE benchmark (8086 code)
	  in 19 seconds.

	10MHz 8088 - WITH 8087 (both @ 10MHz) runs same code in 6.7 seconds.

Hope this has helped.....
