Comparing Raspberry PI, BeagleBone, Mirabox and Wandboard

Came across this post about using the Unix command-line calculator as a quick way to do a CPU benchmark. So I ran it to calculate Pi to 500 digits on various devices I had lying around the house. Take the results with several grains of salt, this was a one-off, and not very scientific at all; I just wanted to get the ballpark. Also note, this is just a math-intensive CPU test, it does not test I/O and most other interesting things.

Machine Processor Time to completion
MacBook Pro Retina (2012) 2.7GHz Intel Core i7 20.0 sec
Raspberry PI Model B Broadcom BCM2835 SoC with 700MHz ARM1176JZF-S 262 sec
BeagleBone
(as part of a NinjaBlocks system)
AM335x 720MHz ARM Cortex-A8 246 sec
BeagleBone Black AM335x 1GHz ARM Cortex-A8 132 sec
Mirabox 1.2GHz Marvell Armada 370 ARM v7 107 sec
Wandboard Quad
(note: this test only uses one CPU)
1 GHz Freescale i.MX6 Quad 115 sec

Updated August 9: added Wandboard. August 13: added BeagleBone Black.
