Which is more expensive ?

I have the following code snippet's. Which one among these would be more expensive ?

Code:

#1
        for (int fd = 0; fd <= 1024; ++fd)
            close(fd);

Code:

#2
        for (int fd = 0; fd <= 1024; fd += 8)
        {
            close(fd);
            close(fd+1);
            close(fd+2);
            close(fd+3);
            close(fd+4);
            close(fd+5);
            close(fd+6);
            close(fd+7);
        }
