GCC vs. LLVM/Clang On The AMD Richland APU

The FLAC audio encoding performance was close as was MP3 encoding.

Overall, the performance between the GCC 4.8.1 and LLVM/Clang 3.3 compilers on the AMD A10-6800K "Richland" APU were close. In some tests GCC 4.8.1 was the obvious winner while in other workloads LLVM/Clang provided a steady lead over the Free Software Foundation's longstanding compiler. Via the Phoronix Test Suite you can easily reproduce these benchmarks or by running phoronix-test-suite benchmark 1306306-SO-RICHLANDG80 you can simply see how your system performs to this 4.7GHz-clocked APU running Ubuntu Linux.
