<<The website you posted shows P-II's FPU being twice as fast as K6-2 in addition/subtraction.>>

For addition and subtraction you want to use integer unit instead of FPU. Integer is much faster than FPU.

<<As far as any processors doing a precision square root function in 10 clock cycles, you are very gullible if you do believe that.>>

I have seen a few published results with similar conclusion. It is the ability to make division and square root faster is what make the K6-2 outperform the PII in 3D geometry transformation.

<<P-II still has a pipelined FPU.>>

The advantage of pipeline FPU has been negated by SIMD FPU. SIMD outperforms pipeline FPU.
