GCC 6.2 vs. Clang 3.9 Compiler Performance On Clear Linux With Intel Kaby Lake

As some fresh compiler comparison numbers are tests of GCC 6.2.0 and LLVM Clang 3.9.0 as currently shipped by default on Intel’s high performance Clear Linux distribution. All other system settings/packages were maintained the same during the testing process as was the same CFLAGS/CXXFLAGS. The MSI Cubi 2 ships with a Core i5 7200U “Kaby Lake” processor.
