that doesn't matter; if you make your cache usage smart and your branches predictable, the CPU will take advantage of that and your program will run faster. It is in the interests of the system and CPU designers to make sure this is the case, and it is.
If you do the things which make your code friendly to the CPU cache and the branch predictor, when it comes time for your code to run on the CPU, it will run faster than it would if you did not do those things.
