Branchless Quicksort Outperforms Standard C++ Sorting Methods

Sorting remains a critical computational task where CPU-level optimization is increasingly important. This research demonstrates that a branchless implementation of Quicksort can measurably outperform widely-used C++ standard library algorithms like std::sort and pdqsort. The findings underscore the value of low-level optimization techniques in achieving significant performance gains, particularly for applications where sorting is a performance bottleneck.
