GCC vs. LLVM/Clang On AMD's FX-8350 Vishera

LLVM/Clang is still known very well for its faster build times.

GCC 4.7.3 is faster than LLVM/Clang 3.3 SVN for the AMD FX-8350 system at the C-Ray multi-threaded ray-tracer.

Without OpenMP support, Smallpt is much faster on GCC.

The performance of LLVM/Clang 3.3 for most tests is at least comparable to GCC when ignoring the OpenMP-based application results. In a few benchmarks LLVM/Clang is faster, particularly when it comes to build times. Overall GCC is still generally faster with the generated application binary performance on the AMD FX-8350 "Bulldozer 2" setup running Ubuntu Linux.
