Branch Prediction - How much does an if cost?

This article uses an analogy of a railroad signalman to explain CPU branch prediction. It details how the cost of an 'if' statement depends on predictability, showing how sorted data leads to faster execution. The content includes a look at generated assembly instructions and discusses factors affecting performance, making it a technical deep dive into low-level optimization.
