ARM Cortex-A15 Exynos5 Compiler Benchmarks

Due to there being much interest in the ARM Cortex A15 benchmarks on Linux, namely with the Samsung Chromebook and its Samsung Exynos 5 Dual, here's a weekend special providing some GCC compiler benchmarks of this new ARM chip.

The benchmarks in this article are of Ubuntu 12.04 LTS loaded up on the Samsung Chromebook with the Linux 3.4 kernel. The GCC 4.6.3 compiler was compared to GCC 4.7.2 with a number of C, C++, and Fortran benchmarks. The same compiler flags were maintained within the test profiles during the benchmarking process. In a future article will be LLVM/Clang compiler benchmarks as well as performance results from the Cortex-A15 compiler tuning.

All benchmarking was handled in a fully-streamlined and reproducible manner using the automated Phoronix Test Suite benchmarking software.
