[Haskell-cafe] [Somewhat OT] Speed

Hi guys. This isn't specifically to do with Haskell, but... does anybody have any idea roughly how fast various CPU operations are? For example, is integer arithmetic faster or slower than floating-point? Is addition faster or slower than multiplication? How much slower are the trigonometric functions? etc. Does using 8-bit integers make arithmetic any faster than using wider values? Does anybody have a good resource for this kind of information?
