Calxeda touts ARM-based web server with 15x better performance/Watt than Intel X

Posted on Friday, June 22 2012 @ 16:14:49 CEST by

Server startup Calxeda introduced the EnergyCore ECX-1000, a new ARM-based web server that it claims offers fifteen times better performance/Watt than a system with Intel's Xeon E3-1240 processor. Full details at X-bit Labs.
Calxeda used similarly configured systems with Ubuntu Server v12.04 (3.2 kernel) and Apache Server v2.4.2 to run ApacheBench v2.3 (16KB request size). Calxeda web server was based on EnergyCore ECX-1000 (four Cortex-A9 cores at 1.1GHz) and featured 4GB DDR3L at 1066MHz, 1Gb Ethernet port and one 250GB 7200rpm Serial ATA hard drive. Intel web-server sported Xeon E3-1240 (four cores with HT at 3.30GHz, 80W TDP) microprocessor, Intel C216 core-logic and 16GB of DDR3 memory.

Power measurements were obtained at a 2-second sampling rate and averaged across the duration of the benchmark run. Power supply overhead and hard drive power consumption were not included in these measurements, however the entire Calxeda EnergyCore ECX-1000 SoC and DDR3 memory are included together.
