Benchmarking ARM boards on WEP-M+2

[Dirk Broer]

The somewhat surprising winner of the 32-bit part of this contest is the venerable old Odroid-C1:

Model	SOC	Speed	Credits/day WEP-M+2	Watts needed	Credit per kWH
Odroid-C1	Amlogic-S805 (Quad-core Cortex-A5)	1500 MHz	600	3.8	6,500
ASUS Tinker Board S	Rockchip RK3288 (Quad-core Cortex-A17)	1800 MHz	960	9.3	4,300
Odroid-XU4	Samsung Exynos 5422 (Octa-core Cortex-A15/Cortex-A7)	2000/1400 MHz	1,670	13.3	5,300

And these three were the top-performing 32-bit boards. The C1 really clobbered the Cortex-A7 equipped Raspberry Pi-2's and Banana Pi M2, and also was better than the Cortex-A9 equipped Hummingboard, that need more power to achieve lower scores.
