If you are curious how the various ARM powered boards currently on the market compare to each other then the gang over at Phoronix has a real treat for you.  They have assembled a plethora of systems including the ODROID C1+, Raspberry Pi Zero, Raspberry Pi 2, Orange Pi Plus, Orange Pi PC, Banana Pi M2 as well as the Jetson TK1, and Jetson TX1 for comparison purposes.  Most of the systems use a Cortex A7 though you will also see an A5 as well as an A57.  The tests are varied as it can be difficult to determine what performance should be benchmarked on these systems although some like the OpenSSL test are obvious.  Since part of the reason you would choose a low power ARM system is the price, they wrap up with a performance-per-dollar rating to help you choose the best valued system for what you need it to do.

"For those interested in small, low-power ARM single-board computers, up for your viewing pleasure today are benchmarks of several different boards from the Raspberry Pi Zero to the Banana Pi M2."
