The Raspberry Pi and the Rikomagic MK802 might seem poles apart in their design and build – the Pi is a bare board running an ARMv6 processor with Linux operating system; the MK802 a complete mini PC using an ARMv7 chip and Android 4.0.
But you can actually run a simple benchtest on the two that will give you at least a basic idea as to their relative processing power. And that’s to calculate Pi to 3000 decimal places.
Yes, the process relies on you installing Linux onto your MK802, however, that’s a pretty simple process and a temporary one – you can install Linux on a MicroSD card, boot up the MK802 with the card in place and it will run the Linux OS; power down, pull the card out and reboot and the mini PC boots back into Android.
To run the benchtest, simply open up a Terminal prompt and type the following:
Time echo “scale=3000;4*a(1)” | bc –l
The best time we got from the Pi was 56.06seconds, overclocked to 900MHz. The MK802 running the 1GB/720p Lubuntu distro at its stock 1GHz clock rate came back in 43.7seconds. Obviously, faster times are better but it gives you at least a ball-park comparison of the relatively performance difference between the two.
The Raspberry Pi runs a 700MHz Broadcom BCM2835 SoC chip, overclockable to 1GHz while the MK802 features a 1GHz Allwinner A10 ARM Cortex A8 processor.
