For those curious how LLVM/Clang compares against the GCC compiler on low-end x86 hardware, here's some numbers.

In testing the ALUSA Atom Desktop for its upcoming review on Phoronix (the review should be published tomorrow), the Intel Atom D525 was benchmarked with the GCC and LLVM/Clang compiler as one of the many different tests run from this low-power system.

LLVM/Clang 3.0 and GCC 4.7.1 were compared while running Ubuntu 12.10 and obtaining the compilers from the Ubuntu Quantal package repository. Below are the results from the Intel Atom D525 system. Full system details, system logs, and other information is available on OpenBenchmarking.org via the 1209140-RA-INTELATOM04 result file.
