GCC vs. LLVM Clang Is Mixed On The Ivy Bridge Extreme
LLVM Clang continues to maintain striking leads over GCC when it comes to the speed of compiling C/C++ code.
GCC 4.8.1 is faster than GCC 4.7.2 for C-Ray, which now makes it noticeably faster than the current stable release of Clang on the twelve-thread Core i7 4960X Extreme Edition.
LLVM Clang is close to landing full OpenMP support, but in the meantime, the GCC performance is obviously much faster on multi-core systems.
