While comparing compiler performance of different Linux code compilers on different software stacks and hardware configurations is nothing new at all to Phoronix, usually it's done on x86 hardware. However, with ARM hardware becoming increasingly common and much more powerful, here's a comparison of the GCC and LLVM/Clang compilers on a dual-core ARM development board.
This latest ARMv7 Linux benchmarking builds upon the Ubuntu 12.04 ARM benchmarks shared on Monday of the PandaBoard ES with its OMAP4460 dual-core Cortex-A9 SoC. The Texas Instruments hardware was running with 1GB of RAM and 16GB SDHC storage. The results today are using Ubuntu 12.04 with its ARMv7 Linux 3.2 kernel and comparing the performance of GCC 4.6 and LLVM/Clang 3.0 as found in the Ubuntu 12.04 Precise repository.
