Without branch prediction and speculative execution, performance would always be as bad as with a misprediction. So every correct prediction is a win, and that’s why it’s being done. > My broad takeaway of the whole ordeal is that I'm basically avoiding if-statements these days. That seems like an overreaction. For most applications, cache locality and using the right algorithms is more important, if performance is an issue at all. |
