Krazy: prefix vs. postfix ++ and -- operators

Krazy says:

"You should use ++ and -- as prefix whenever possible as these are more 
efficient than postfix operators. Prefix increments first and then uses the 
variable, postfix uses the actual; the variable is incremented as well. 
Because of this, the prefix operators are inherently more efficient."

Considering that today's CPUs have multiple pipelines, using a value directly 
seems faster to me than waiting for it to be incremented or decremented.

Is this krazy warning still correct?
