Benchmarking ARM boards on WEP-M+2

[Dirk Broer]

I've started a new chapter in benchmarking: I bought myself a power consumption meter, to be able to have the exact wattage that a system runs on.

So far I had the exact values for runtime, CPU time, and credits and was able to get the exact Per day/proc score. The Credit per KWh however was an estimate based partly on the wattage, which in practice meant the TDP value of the CPU -if known, such as e.g. with ARM boards.
But in the future I will now be able to report the exact wattage of e.g. an ARM system when running Wanless -or any other project/BOINC platform.

The first competition will be between my best 32-bit boards: The Odroid-C1, the Odroid-XU4, and the ASUS Tinkerboard S on one side versus my worst 64-bit boards on the other side: the Raspberry Pi 3B's (both original version, not 3B+). All losers will be retired in favour of additional better performing 64-bit boards. Pretty expensive buggers though: the 8GB nVidia Jetson Orin Nano devkit and the 16GB Radxa Rock 5B are the most likely candidates.

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.
