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. Probably means the s... hot risc inside the K6 loops real fast compared to the cisc Pentium. 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 registers. I do not know how the K6 is constructed. I must find out. --David David Teague, [EMAIL PROTECTED] Debian GNU/Linux Because software support is free, timely, useful, technically accurate, and friendly. (Thanks guys!)

I get the same number with my P5 166s. Is your 225 a P-Pro? They changed something (I can't remember off hand, I want to say bus size) and that could account for the difference.

Re: What are the Bogomips for a P166?
Pedro, You should really ignore the BogoMIPS rating. It doesn't make any sense. On my dual 90MHz Pentium, I get 72 BogoMIPS. On my notebook computer running a 200MHz MMX Pentium, I get 399 BogoMIPS. And on my 300 MHz Pentium II, I get 307 BogoMIPS. It makes no sense whatsoever. Furthermore, there is virtually no speed difference between my 200 MHz Pentium MMX notebook and my dual 90MHz workstation. Allen -- Linux: If you're not careful, you might actually learn something.
