GCC 16.1 released at the end of April as the latest major, annual feature release to the GNU Compiler Collection. Early benchmarks showed some nice leads for GCC 16 over GCC 15. Continued testing of the new GCC 16 compiler has continued to show overall better performance of the resulting binaries than using GCC 15 on the same hardware and same compiler flags. That led many to wonder about the GCC 16 performance up against the latest LLVM/Clang open-source compiler, which is the focus of today's benchmarking showdown.
