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.
