Rewrote it with help from AlexExtreme, my Athlon XP 3200+ 2.2GHz gets 986487165 floating point calculations done in 10 seconds and took 73 seconds to calculate pi to 20000 digits

Ok, here's a benchmark specifically targeted at floating point AMD vs. Intel:

Pi...


This is a step in the right direction.  Ok, this is actually fun.  Havn't checked the pi algorithm yet, but it looks like real math.

Celeron 460 MHz with 128 KB of cache takes 328 seconds to calculate Pi .  Using level 2 optimization on GCC cuts this to 182 seconds.  
 
My advice:  just drop the looping (it really is meaningless), and add some more real life problems.  I'd love to see the performance comparisons between people boxes, both with no optimization and -O2 flags.

I'll do my Athlon64 X2 4400+ system when I get home. :)

Hmmm ... how do I compile it ? (I know it's a stupid question, but unless it's got a makefile, I have no clue)
