    Thank you, I love these types of articles!

    Page 45 of that article has a great speed comparison. It is a program that prints out the squares and cubes for numbers 1-100. It’s a so-so comparison because it depends so heavily on the text output. I remember my Apple II would run this faster than a Mac because the Mac was so busy drawing the proportional characters on the screen, while the Apple II had hardware to draw simpler characters.

    The times were:

    PC-1 3:50 (3 minutes, 50 seconds)
    PC-2 0:44
    Model III: 0:14

    For fun, I ran it on my laptop:
    0.000u 0.000s 0:00.00 0.0% 0+0k 0+0io 0pf+0w
    … too fast!!

    Measuring it with more precision, I got 54061 nanoseconds:
    i7 from 2011: 0:0.000054

    That is about 800,000x faster than the PC2. Or 70 clock cycles of the PC2 – About the time to add 10 bytes.
