FLAC and MP3 audio encoding performance was faster with the Clang-compiled binaries in place of the GCC binaries.

Clang still has some work ahead with the HINT performance compared to GCC.

Overall, the LLVM/Clang vs. GCC performance was quite fierce and with this Athlon 5350 is the most competitive we have seen Clang against the Free Software Foundation's compiler. In many benchmarks, Clang was matching GCC's performance while in other tests it had a strong advantage. Of course, Clang held its ground well in blowing past GCC for compile times. GCC's advantages come down to the OpenMP support and in select workloads where it still produces better optimized code over Clang.
