I have no idea how you reached this conclusion, given that the numbers you have provided are in total contradiction.

A ~400+ MHz processor today is definitely NOT desktop-class for 1993 when the average was a 486DX. I mean, I was there. You are a decade off, if you want to include all the architectural improvements that even a cheap CPU today has.

Okay:

So it's definitely better than desktop-class for 1993.
