If you think so it can only be because you've never run a 486 based machine!!!!
Although 14 MIPS may be a bit over(11 seems to be more like it with a 128Kb
external cache!) The 486 IS A SCREAMER!!!

The reason being that most instructions execute in fewer clockcycles than the
386.

Go have a look.... You'll be impressed.
