Hi Colin

There is a formula for bogomips for most chips,
the documetnation witht he bogomips package will
give that.

For the K6 series is is approximately 2*clock speed.
My K6-2-350 give s a bogomips of about 700. 
The Pentium gives a muchslower number, about =
the clock rate. At least that is true for the 
Pentium 266 I'm on right now. Bogomips = 267.

Believe it or not: The Pentium is a risc processor so 
far as the small instructions. The internal architecture is
exactly RISC. The multicycle instructions are, as you suggest,
CISC. There is an array of hidden registers in the chip that 
are used in exactlty the same way a RISC programmer uses 

I do not know how the K6 is constructed. I  must find out.
