Hardkernel have released a $US70 4GB single board computer based on the Amlogic S922x CPU called the Odroid N2. The S922x CPU contains a quad-core Cortex-A73 as well as a dual-core Cortex-A53. So the cpu can run frugally on the Cortex-A53 cores when demands are low. Reducing power consumption to an incredibly low 2.3 watts from the wall, when the desktop is idling.
With a power consumption of only 2-8 watts I really wasn’t expecting much in the way of desktop performance, but was pleasently surprized. The Mali-G52 MP4 GPU isn’t as fast as say a Intel HD Graphics 4000 (Mali-G52 MP4 GPU benchmarks some 50% slower than HD Graphics 4000 in 3DMark Ice Storm Unlimited), but it doesn’t do a bad job at running the MATE desktop in Ubuntu Linux.
The Odroid N2 arrived with Ubuntu installed on an eMMC module so I was easily able to install NGnix to do some performance tests. The arms in the little N2 certainly have legs. It was able to complete 965 req/s to point where my gigabyte lan became the bottleneck. In running the test, the power consumption of Odroid N2 increased from 2.3 watts to 2.9 watts.
The Odroid N2 makes a perfect light web server. Especially if you only need to serve static web pages to the public. The Odroid N2 is a fanless low consumption device that can easily double as a NAS or media centre. The sbc also comes in handy if you want to compile directly on the arm architecture. Lazarus Pascal and FPC happily run on the Odroid N2.
The web server for this site is currently running on an Odroid N2.
