CPU Benchmark - Raspberry PI vs Banana PI - single core speed test with Fibonacci Sequence

In this short article, I would like to show the results of a simple CPU test made on Raspberry PI and Banana PI using Fibonacci Sequence, run on a single core.

Test result:

Note: smaller calculations time means the pc is faster
(e.g. Banana PI M3 is 1.65 times faster than Raspberry PI 2 B+ on single core computation)

Note: below tests were compiled with GCC (with disabled optimization).

Used test (program.cpp file):

//CPU test

#include <iostream>
#include <time.h>

int main()
{
    unsigned long tmp, a = 0, b = 1;

    //std::cout << a << std::endl;
    //std::cout << b << std::endl;

    std::cout << "Started!" << std::endl;

    time_t t1 = time(NULL);

    for (unsigned long i = 0uL; i < 10000uL; ++i)
    {
        for (unsigned long j = 0uL; j < 1000000uL; ++j)
        {
            tmp = b;
            b = a + b;
            a = tmp;

            //std::cout << b << std::endl;
        }
    }

    time_t t2 = time(NULL);
    time_t dt = t2 - t1;

    std::cout << "Finished!" << std::endl;

    std::cout << "Result: " << b << std::endl;
    std::cout << "Time: " << dt << "s" << std::endl;

    return 0;
}

Compilation:

g++ -o program program.cpp

# or:

gcc -o program program.cpp

Running

chmod a+x ./program
./program
