Obviously, a P3 1000 mHz is more than 5 times faster than a pentium 200 mHz. Is there another standard measure of CPU performance which accounts for the difference? For example, if it were called 'x', you could say a CPU's performance was CPU speed times 'x'. I know this would differ based on the type of benchmark (integer math, floating pt math, 3D, etc). Would instructions per clock cycle be something like this?
