ARM On Ubuntu 12.04 LTS Battling Intel x86?

Linux on ARMIn recent weeks I have shown how Ubuntu 12.04 is ARM-ing up for better performance on the ARMv7 architecture by enabling hard-float builds and how the TI OMAP4 support has come together resulting in significant performance gains. Nevertheless, how is modern ARM hardware now comparing to the low-end Intel x86 competition? In this article are some results from Ubuntu 12.04 comparing the ARM performance to some Intel Core, Pentium, and Atom hardware.

Late last year I delivered the first ARM Cortex-A9 dual-core benchmarks of a PandaBoard ES with the Texas Instruments OMAP4460 SoC. Those initial results were okay in comparing to various low-end Intel CPUs, especially considering the lower power consumption of the ARM hardware. However, now the Ubuntu ARM performance is much faster thanks to hard-float and then for the OMAP4 series there is the proper cpufreq / power management support so the OMAP4460 can scale to its full dual-core 1.2GHz speeds. As a result, here's a fresh set of ARM and Intel benchmarks from an Ubuntu 12.04 development snapshot with the Linux 3.2 kernel.
