Re: "For code that isn't memory bound, we have the 3dnow execution upto 4x the non-3dnow code. The problem is Seti is always memory bound."

I run the program on 2 Celeron systems. The first is an overclocked 450/100 and the second is a 433/66. At first glance one would expect little difference yet the 450/100 is ~25% faster showing an application where bus speed is very significant!

Is this often the case, in your experience?

What about some proper data alignment? I've heard that most compilers produce pretty bad alignment.
