I won't switch to LLVM/Clang even if it's the absolute winner on all benchmarks by a big margin.
And some compilation benchmarks really show a suspecting difference. The compilation on LLVM/Clang is parallelized by default? I know that on GCC that's not true.

Micheal, the compilation times seem to be out if the norm here
I know CLang is fast but this seems to be excessively fast in the compiling tests. This makes me wonder why, is Clang making better use if all of the cores in the machine? Or maybe GCC wasn't using the cores at all. I expect better compiling times but these are a blow out.

Phoronix: Clang Fights GCC On AMD's Athlon AM1 APU With Jaguar Cores
A few days ago I did my latest benchmarks of GCC vs. LLVM/Clang and that was using an Intel Core i7 4770K "Haswell" processor. The tables have now turned and in this article are GCC vs. LLVM Clang benchmarks of the AMD Athlon 5350 APU with four Jaguar CPU cores.
