Dual-Core ARM Cortex-A15 Linux Benchmarks Continue: After having a few more days to run and benchmark the Samsung Chromebook, it continues to be a very interesting notebook computer. For $250 USD this notebook packs a Samsung Exynos 5 Dual SoC, which bears a dual-core 1.7GHz ARMv7 Cortex-A15 processor and delivers rather good performance results.
GCC 4.6/4.7/4.8 ARMv7 Compiler Benchmarks: As some more benchmarks from the Calxeda EnergyCore ECX-100 ARM Server -- a.k.a. the "5-Watt Linux Server" -- to share this weekend, here is a ARMv7 Cortex-A9 GCC compiler performance comparison.
Ubuntu 12.04 LTS ARMv7 Linux Performance Gains: Earlier in the Ubuntu 12.04 LTS "Precise Pangolin" development cycle I noted some performance improvements happening on the ARM side, particularly for Texas Instruments OMAP4. Namely, Ubuntu 12.04 was ARMing up for better performance with ARM hard-float support and the performance becoming more compelling for the PandaBoard ES hardware with proper cpufreq support.
LLVM/Clang On The ARMv7 PandaBoard ES: Here's a quick look at running the LLVM/Clang compiler on the OMAP4460-based PandaBoard ES compared to the default GCC compiler.
