Ubuntu 12.04 LTS ARMv7 Linux Performance Gains

[Alejandro Nova]

A comparison between GCC and LLVM/Clang is meaningless for us. A better bet could be a comparison between ARMv7 and Atom performance, considering the performance improvements introduced with Ubuntu 12.04. The last time such a comparison was made, Atom won by a small margin. Maybe these performance improvements turn the table...

Phoronix: 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. In this article is a comparison of the Ubuntu 11.10 and Ubuntu 12.04 ARM performance.
