Calxeda ECX-1000 Benchmarks vs. Intel Atom, TI OMAP4

2012-Oct-25 | Tags: benchmarkcalxedaintelservertexasubuntuversusx86

Linux on ARMLast week I began delivering benchmarks of the low-power yet massively scalable Calxeda EnergyCore ECX-1000 ARM Server and followed the initial tests with some ARM compiler benchmarks and other benchmarks from this 5-Watt Linux Server.

In this article is what many Phoronix readers have been waiting for: comparing Calxeda's quad-core Cortex-A9 ARMv7 performance against a dual-core Texas Instruments OMAP4460 PandaBoard ES and then an Intel Atom processor.

When all of the systems were running Ubuntu 12.10 with the Linux 3.5 kernel, the 1.1GHz and 1.4GHz Calxeda ECX-1000 EnergyCore nodes were compared to a PandaBoard ES and an Intel Atom NetTop. The PandaBoard ES is the development board for the Texas Instruments OMAP4460 SoC, which has a dual-core ARM Cortex-A9 processor with each core operating at 1.20GHz. The Intel Atom NetTop was the ALUSA Atom Desktop with an Intel Atom D525. The Intel Atom D525 has two physical cores plus Hyper Threading, thus four logical cores, and a 1.8GHz operating frequency. The TDP on the Atom D525 is 13 Watts.
