Re: [TCLUG:19571] [OT] How many mult/second?



Actually, there are two ways to measure a flop:

- A mult _or_ an add
- A mult _and_ an add

I believe that the "old" way is the latter and the "new" way is the former, 
though I'd have to check my Numerical Analysis book to make sure.

Intel's chips aren't really capable of many flops in comparison to some of the
other beastly CPUs out there (e.g. DEC (compaq) Alpha - the king of flops, IBM's
Power series cpus, SGI's R10k, etc)
